The invention relates to a printing ink or printing the lacquer for food packaging or for contact devices, which can come into contact with food products, comprising a binder substance with a resin component and a component of the solvent.

As a rule, in the packaging of food products distinguish primary packaging and secondary packaging. In immediate packings of a on the outer side of the packaging, usually printed, the food product is in the container, in contact with the inner side of the package opposite the outer side. In the secondary packaging of the food product placed in the additional membrane, which is located in particular in napechatannoe on the outside of the package.

Examples of contact devices, which may be in contact with the products and, in particular, can come into direct contact, are tabs in food packaging or the substrate for food, such as tabs in the trays.

In principle, the components of printing inks and printing varnish can get through the packaging to the product, particularly in immediate packings.

In EP 0 886 671 BI described offset printing ink, which comprises a rosin modified phenolic resin and/or maleic resin and/or modified hydrocarbon resin, and/or the ester of rosin. As solvents for resins/resin this offset printing ink has one or more water-insoluble esters of fatty acids of some polyhydric alcohols with high steric bulk and/or atenolol, and esters have steric size diameter of from 2.0 to 7.0 nm and volume from 1.0 to 21.0 nm3. This offset printing ink is described as paint, low migration and low odor, and swelling.

In the article "Spinach - and only spinach!" Klaus-Peter Nicholas (Klaus-Peter Nicolay) in Druckmarkt 40, February 2006, 30-32 described printing ink with minimum migration marking MGA manufacturer of paints Huber. They are not dry by oxidation and slowly absorbed. Require varnishing "inline" (in-line) with dispersion varnish.

Technical information 10.1.15/11.2006/Verpackungsdruck/Offset-Druck "MGA CORONA® 5045" Huber group similarly described touch the neutral sheet offset inks with a low degree of migration for the manufacture of food packaging. These printing inks contain only components with minimal potential migration to substantially prevent undesirable interaction of the ink with the Packed products. These printing inks do not dry by oxidation and absorbed relatively slowly; it takes varnishing "in line" with the help of di is dispersed varnish. Materials to print with a slight suction abilities require the use of special dispersion coatings. Disclaimer coating in-line entails otmerivanie in the foot and not achieved the necessary resistance to abrasion.

From USA 5178672 known printing ink based on soybean oil.

In USA 2004/0086603 A1 mentioned edible ink for inkjet printer.

From DE 10209013 A1 known offset printing ink, which contains pigments and binder for the pigments and the binder comprises at least one epoxydecane organic component.

The basis of the invention lies task is to provide a printing ink and printing lacquer for food packaging mentioned at the beginning of the form that are used in a simple way.

This problem is solved using the first ink or the specified first printing varnish according to the invention by the fact that component of the solvent of the binder is a one-component or multi-component saturated solvent for the resin, and a solvent or components of the solvent are a food product or an additive to food products.

The binder comprises a resin component (one or more resins and the solvent is to dissolve the resin. In printing inks prepared for the manufacture of printing ink binder for pigments, also referred to as linseed oil.

According to the invention a component of the solvent of the binder is a one-component or multi-component saturated solvent for resins, and solvent (if it is one component or components of the solvent (if solvent multicomponent) is a food product or an additive to food products. Chemical drying and, in particular, oxidative-drying printing inks/printing varnish is prevented through the use of a saturated component, solvent printing ink or printing varnish when/after printing. Not the formation of fission products (by oxidative cleavage of multiple bonds), which can migrate to the packaged product, which is placed in napechatannoe appropriate packaging. Fission products such also, in principle, can go into the gas phase and cause a decrease in the intensity of the odor, and swelling. When the solution according to the invention they are prevented to a great extent.

If a component of the solvent consists of permitted food (one-component or multi-component or single-component or multicomponent permitted food is Oh supplements the migration component of the solvent in the food product is not harmful. If a food product or food additive choose neutral touch, then there is no deterioration in the quality of the food, which is food packaging, napechatannoe corresponding printing ink or relevant printed varnish.

A food product according to §2, para. 2 of the Code of laws on food and feed means (LFGB) is defined as the product in accordance with article 2 of Regulation (EC) No. 178/2002. In accordance with the above Regulations food are all substances or articles which for this purpose or from which it is only common sense to expect that people use in their processed, partially processed or unprocessed form.

According to §2, para. 3 of the Code of laws on food and feed means additives to food are substances with or without nutritional value, which, as a rule, are not used either as itself a food product or as a typical ingredient of the food product, and which add to the product based on the technological basis for the manufacture or processing of, in consequence of which they or their cleavage products, or the products of reaction mediated directly or be or may become an integral part of the food product.

Thanks to the solution according to the invention produce printing inks/printing varnishes, which can be handled simply. Perelechenova is not necessarily required. Not is harmful contamination of food, as he infects the product is a food product or a permitted food additive. So to a certain extent also Pets migration. Consequently, printing ink/printing varnish can dry by absorption.

Printing inks/printing varnishes according to the invention is implemented, for example, offset printing inks/printing varnishes and, in particular, as a sheet of printing ink/print varnishes.

In particular, in the printing ink according to the invention and a printing varnish according to the invention is not binding chemical components. In addition, the solvent and/or resin there is no need to dual relationships, which lead to plenkoobrazovatel. In known printing inks that dry by oxidation, resin and/or oil solvent to form a film on the basis of double bonds in the absorption of oxygen, initiated by metal components such as salts of cobalt and/or manganese salt. As described in DE 10209013 A1, instead of oxidative drying, film formation can be achieved also thanks to the use of, at IU is e, one epoxidizing component, whereby opening, at least one epoxidizing component calls the film formation and, together with the stitching.

In the solution according to the invention, film formation (crosslinking) occurs. Accordingly, should not be used as desiccants metal ions.

Turned out to be favorable, if the solvent (if a single component or components of the solvent formed of carbon compounds with fatty acids with chains of medium length. For example, oil is used MCT (MCT - middle chain triglyceride is a triglyceride with an average chain length). Consequently, it is possible to provide a solvent which is liquid under normal conditions for printing inks/printing varnishes.

In particular, the carbon chain of the solvent component of the solvent includes from 6 to 12 carbon atoms.

Turned out to be favorable, if the components of the solvent drying oils include monoglycerides (monoacylglycerol) and/or diglycerides (diacylglyceride), and/or triglycerides (triacylglyceride). The relevant substances allowed as food. However, they can onecomponent to form a solvent to form a solvent mixture. The corresponding fatty acid (allowee remains of) these components of the solvent include, in particular, the IRNA acid (allowee residues), which have a carbon chain length from 6 to 12.

Is also possible that the solvent includes, alone or in combination acetylated or esterified monoglycerides and/or acetylated or esterified diglycerides and/or acetylated, or esterified triglycerides. For example, as components of the solvent use appropriate emulsifiers. Possible components of the solvent are, for example, monoglycerides and diglycerides of fatty acids esterified food acids such as ethyl ester acetic acid, (E a), ester of lactic acid (E 472b), ester of citric acid (E s), ester of tartaric acid (E 472d) etc.

From C2up With24-aliphatic, straight chain monocarboxylic acids of natural fats and synthetic origin) and their mono-, di - and triglyceridemia esters according to the EU Directive 2002/72/EC (On the materials and objects made of polymer, which are intended for contact with food products) is allowed as additives without restrictions. Print on food packaging or contact devices of the respective printing ink or relevant printed varnish conforms to the requirements contained in article 3 of Regulation (EC) No. 1935/2004 for food goods of first necessity to the spine.

In the highest degree advantageous is if the component of the solvent of the binder, in fact, does not contain multiple bonds and, in particular, contains no double bonds. Because of this essentially prevents oxidative cleavage products. Thanks again slightly deducted able to migrate the share of printing inks/printing varnish from the fission products. Further as a consequence also receive printing ink and printing lacquer with a slight odor, and swelling. The amount of swelling depends on the size of the molecules of the solvent used.

In particular, the solvent is (if it is a single component or components of the solvent have an iodine number less than 10 and preferably less than 1 to slightly hold the oxidative cleavage products. Particularly preferably iodine number is less than 0.4.

In the future turned out to be more favorable than if the solvent molecules or components of the solvent have a molecular weight less than 1000 daltons. Consequently, an improved printing properties of the corresponding printing inks/ printing varnish.

Can be beneficial, if a component of the solvent of the binder is a mixture of several substances that are food or permitted food d is the additive). Consequently, it is possible to adjust the properties of printing inks/printing varnish by appropriate selection of the components of the mixture.

Turned out to be advantageous if the weight fraction of binder in a printing ink is between 50% and 80%. Thanks to this good printing technical properties with good print result. In print varnish proportion of binder may be higher.

Printing ink includes a pigment. The weight proportion of the pigments can be up to 35%.

May be provided so that printing ink/printing lacquer contains one or more alkyd resins. Through alkyd resins can be wet pigments. This allows them to better distribute across the Board and in the print result receiving high gloss (Here alkyd resin is regarded as separate from the binder component; the corresponding data weight refers to the fact that the binder does not contain alkyd resins. However, the alkyd resin can also be attached to the binder substance).

In particular, the weight proportion of alkyd resins is below 15%. For example, it is below 10%.

May be provided so that printing ink/printing varnish contained additives for printing, such as, for example, the paste for high resistance to abrasion.

Is favorable, if the weight doskonalenia solvent is at most 45%. Component of the solvent, in particular, in the thick ink is less than 45%. For example, it may be less than 40%.

Favorable printing ink/printing lacquer according to the invention dries by absorption, perelechenova is not necessary.

Component of the solvent in particular is a liquid.

Profitable printing ink according to the invention or printing varnish according to the invention does not merge in the network, i.e. also no film formation on the basis of stitching. Consequently, should not be provided by components stitching with double bonds or at least one amoxicillinum component.

In particular, the printing ink according to the invention or printing varnish according to the invention has no epoxydecane components. Epoxydecane components, in principle, could migrate into food. If epoxydecane component is not used, then the receipt can be simplified, as when you receive a binder, cooling is not necessary. In printing inks with epoxydecane components before the adulteration of epoxide may be necessary cooling based on the reactivity of the epoxide.

Printing ink according to the invention or printing varnish according to the invention further are free from metal ions, acting as the wasp is Italy. Metal ions in the ink, known from the prior art, used as a desiccant.

Profitable printing ink according to the invention or printing varnish according to the invention do not contain mineral oils. Mineral oils are undesirable in connection with food products.

Printing ink according to the invention or printing varnish according to the invention can best way to apply for food packaging or contact device, which can be in contact and, in particular, in direct contact with food products.

Printing ink according to the invention or printing varnish according to the invention in particular is an offset printing ink/printing varnish, which can be used for offset printing and, in particular, for sheet offset printing.

In the specific example of the execution of printing ink first, get a binder or the original binder. For this component of the resin dissolved in the solvent by heating. Thus the typical temperature is about 200°C. the Dissolution occurs under stirring. Additionally it may be provided by protective gas atmosphere with an inert gas.

In the obtained binder or the original binder weighed pigments. If necessary, dobavlaut alkyd resin. In the apparatus for dissolving a preliminary dispersion by mechanical action, for example, using disk stirrer. Fine dispersion is additionally, for example, in the rolling mill of the trio.

Then, if necessary, to the original binder substance you can add another solvent to adjust the rheology of the ink. This added solvent can be considered as a component of the binder.
