(57) Abstract:

Purpose: water-based printing ink for paper-based texture imitation of the pores of the wood. The inventive printing ink contains, %: pigment 5-14, the best choice latex (dry substance) 12-15,4, dispersion of polyurethane anionic water (dry substance) of 7.8 to 10.2, lacquer protein (on dry matter) of 1,5-2,3, aqueous paste of ceresin (on dry matter) of 6.0-11,5, aqueous emulsion of oligoetoxichlorsiloxane (on dry matter) of 0.6 to 1.8, ethylene glycol or butylcarbamoyl 1-3 and water - the rest. Paint helps to get prints with high resistance to wet abrasion - 33 progress and to aqueous impregnating composition - 2 points, prevents the formation of water insoluble ink film on the equipment and in storage, is resistant impregnating composition and suitable for obtaining products without subsequent coating. 3 table.

The invention relates to the field of printing, in particular to water-based printing inks for paper-based texture imitation of the pores of the wood used in the manufacture oblivioni films for furniture.

Known printing ink, p is UNT 5-14

The best choice latex 50-65

The disadvantage of this paint is the formation of water insoluble film on the process equipment and the storage of the paint.

When the inevitable stops printing machine related adjustment decoration (color), replacement of the rolls of the paper base, the breakage of the paper web, other technical reasons, is the paint drying on the work items, including on the plate cylinder. The resulting insoluble in water and colorful film leads to clogging of the printing form elements and ultimately weakening effect of steam formation, i.e., to reduce the height of the roughness profile of colorful barcode.

In addition, the formation of water insoluble ink film causes an individual nephropidae and spots, banding squeegee, is hampered by the wash of ink from the printing machine (the use of toxic organic solvents (toluene, white spirit)).

All this reduces the quality of products and proizvoditelnochti them on paper-based texture work prints not resistant to wet abrasion (2-3 turns) and water treatment (5 points).

The purpose of the invention to develop paint, not forming insoluble in water and colorful film on process equipment and storage.

The goal is solved by the fact that the known paint containing the pigment, the best choice latex, lacquer, protein, water paste ceresin, aqueous emulsion of oligoetoxichlorsiloxane, ethylene glycol or butylcarbamoyl further comprises a dispersion of a polyurethane anionic water in the following ratio, wt.

The change in the inventive paint quantitative composition the best choice latex and additional content polyurethane dispersion anionic water was allowed to get a paint that does not form a water-insoluble ink film on the process equipment and the process of storing not less than 6 months is Lenka/.

Such properties of the ink as resistance colourful print to the action of aqueous impregnating solutions, resistance to exposure to light, temperature resistant colorful print, resistance to contact heat, the optical density of colorful prints, adhesion colourful print to the water covering lacquer, paint the claimed composition remained at the level of a prototype.

The dispersion of the polyurethane anionic water /grade POULAN/ is a product obtained by dispersing in water anionic modified polyurethane.

The components were mixed in proportions in accordance with the table. 2.

The content in the paint dispersion of polyurethane anionic water at exorbitant amount on the one hand prevents the formation of water insoluble ink film, and on the other hand does not provide resistance to the action of aqueous impregnating solution.

Printing the claimed composition was performed on the paper-based material facing roll on THE 13-7308001-716-88 (smoothness 15-17) brands of the PPR-1 and PPR-2 and paper-based firm MD (Germany) smoothness of not less than 40 C.

First on the paper-based printed textured picture paint series SG 1.10.1 one or two printing cylinders for gravure printing machine company "albert Frankenthal" Germany, then a separate printing cylinder on the same machine printed at a speed of 80-100 m/min is tava unlike the prototype can be stored for at least 6 months, not forming a water-insoluble film and does not dry on the equipment when necessary technological stops printing process.

Thus, the use of the proposed paint will ensure the quality of printed products, simplify operation of process equipment and increase productivity.
