(57) Abstract:

Purpose: paints for high or offset printing relate to the production of printing inks designed for printing high or offset methods on different types of paper books and magazines, and graphic products. The inventive paint contains pigment, rosin-maleinate resin or phenol resin, a modified rosin, pentaftalevyh resin, a modified vegetable oil, a mixture of three oil fractions, characterized by different physico-chemical properties, polyethylene wax, desiccant, diludid - 2,6 - dimethyl - 3,5 - dietoksikarbonil - 1,4 - dihydropyridines. Paint for high and offset printing has a high speed of consolidation (a low degree of otmerivanija) and high stability technological properties in the ink system with a minimum content of vegetable oil. table 2.

The invention relates to the printing industry, namely to paint for high or offset printing on paper.

Known ink for offset or letterpress, containing in its composition the pigment, solid and liquid resins, vegetable and mineral oils, org is S="ptx2">

The drawback of such paints is the low stability of the printing technical properties for printing machines (drying on the shafts), high viscosity and stickiness.

These deficiencies significantly impacts the performance of printing machines, degrade the quality of printed products, increase waste printing ink during storage, do not allow you to print them on various kinds of paper.

Known offset ink for four-color printing (2), containing 18-20 wt. pigment, 27-33 wt. phenol-formaldehyde resin, modified rosin, 4-9% alkyd resin (ortho), 27-33% linseed oil, 13-22% of high-boiling petroleum solvents, 1-3% of plastic paste, 1-2% naphthenate-cobalt drier.

The paint is satisfactory rheological properties (viscosity, stickiness and durability of prints to abrasion. However, this paint is characterized by low stability printing technical properties on the shafts of the printing machine dries after 6 h, it is not possible to print on various kinds of paper.

Low stability leads to frequent products of the inking units, i.e. unproductive working time and increase the cost of hybrid washing agent operation m is redients and achieved a positive effect closest to the declared paint is paint for high or offset printing (3), containing as alkyd resins resin-based ortho - or isophthalic acid, pentaerythritol, sunflower or linseed oil and waste poly (ethylene terephthalate) at a ratio 2:1:8:2 1,5:1:8:2,5 and advanced pentaerythrityl ether malaysiaand rosin in a mixture of linseed and transformer oils with a ratio of their respective 1:1:2 and phenol-formaldehyde resin in linseed oil at the ratio of their respective 1:1 with the following content, wt.h.

As polyethylene waxes used wax PV-200, PV-300 (TU 6-05-1516-77), zerdusht 3620 (firm "Hoechst"), AF-30 (firm BASF) Germany.

In accordance with the invention, low viscosity and stickiness of the paint, the high speed of its fastening on the paper are provided by the set ratio called oil fractions.

High stability of the working properties of the ink in the ink system of the printing machine provides an introduction to its composition of Dyudina.

The offered paint is used for offset printing and high ways on coated and uncoated papers.

The invention is illustrated in the examples presented in table.1.

The paint on the table.1 the examples are made in three stages.

Under vigorous stirring in a mixture of petroleum solvents dissolve the solid resin followed by addition of a solution of an alkyd resin. Cooled to room temperature, the solution (binder), pigment, drier, polyethylene wax, diludid load in the ratio indicated in the capacity of the kneader equipment and PE is its equipment (three-roll machine or ball mill), where is the dispersion until the pigment particle size not more than 10 μm on the "wedge".
