Description

four

This invention relates to lacquer materials. The proposed ink can be used to print on the surface of plastics, foils, cellophane, glass and paper.

A printing ink is known which consists of a modified formulphide resin resin, oli and related additives. When the ink dries quickly, the mold cells become clogged on the printing plate (stencil).

To eliminate this drawback, substances selected from the group comprising tetrahydronaphthalene, decahydronaphthalene or methylcyclohexanol are included in the paint formulation.

Example. In a bead mill load 2.8 kg of phenol-formaldehyde resin, modified rosin (brand E-12), dissolved in 1.5 kg of solvent (0.83 kg of toluene, 0.17 kg of ethyl acetate, 0.5 kg of cyclohexanone), 3.0 kg of pentaphthalic drying oil PFL-10-300, 0.5 kg of cobalt naphthenate (desiccant), 1.0 kg of lacquer red lw, 1.0 kg of printed white 825 (filler) and 0.05 kg of tetrahydronaphthalene a. Paint fray to a dispersion of 5-10 microns. The dye is diluted with ethyl acetate to obtain the desired viscosity.

paint characterizes obtained, indicators: the following Time vyyratura, ° C:

18-20 10-15 40-60 60 5-6. 6-7 90 2-3 2-3

Abrasion resistance on the IS-1 device (max. Load) 2600 cycles, 5 elasticity on the MG-1 device 5 days after complete drying of 1 mm, elasticity after irradiation with the PRK-2 lamp for 2 hours at 30-35 ° C varies, gloss is excellent, chemical resistance is excellent.

When printing, the ink does not clog the printing plate cells. The clarity of the print is excellent.

Example 2: 2.4 kg of rosin 5 of a modified phenol-formaldehyde resin grade B-12, dissolved in 1.1 kg of a solvent mixture consisting of 0.75 kg of toluene, 0.23 kg of cyclohexanone and 0.12 kg ethyl acetate, 2.8 kg of glyphthalic drying oil GFL-10-200, 0.56 kg of cobalt naphthenate, 2.1 kg of yellow light-resistant pigment 2 3, 0.7 kg of printed white 825 and 0.08 kg of methylcyclohexanol are mixed and ground to fflJcnepcHocTH 5 -10 microns The dye is diluted with ethyl acetate to obtain the desired viscosity. The paint properties are similar to those of paint prepared in Example 1.

Example 3. 2.8 kg of rosin modified E-12 modified phenol-formaldehyde resin dissolved in a solvent mixture consisting of 0.84 kg of toluene, 0.17 kg 5 of ethyl acetate and 0.52 kg of cyclohexanone, 3.0 kg Polymerized printing linseed linseed oil weakly, 0.58 kg of cobalt naphthenate, 0.92 kg of blue phthalocyanine pigment, 0.85 kg of printed white No. 825, and 0.05 kg of decahydronaphthalene are lured and frayed to a dispersity of 5-10 microns. The dye is diluted with ethyl acetate to obtain the desired viscosity.

five

The paint properties are similar to the paint obtained in examples 1 and 2.
