FIELD: paint industry.
SUBSTANCE: invention relates to compositions of a pigmented coating based on organic solvents. Composition of the pigmented coating is proposed containing an organic solvent and, based on the total amount of the coating composition, from 0.02 to 0.75 % wgt of at least one copolymer (A), where the copolymer (A) is obtained by copolymerization of a mixture of olefinic unsaturated monomers (a) in at least one organic solvent, while the mixture of monomers (a), which is subjected to copolymerization, consists of (a1) 10–60 mol. % at least one monomer of formula (I), where R1=C1-C4 alkoxy, R2=C1-C4 alkyl and m=0, and (a2) 40–90 mol. % at least one additional olefinic unsaturated monomer, where at least 80 mol. %, preferably 100 mol. % of monomers (a2) are selected from the group consisting of monomers H2C=CH-C(=O)-ORx, H2C=C(CH3)-C(=O)-ORx and H2C=CH-OC(=O)-Rx, where Rx is an alkyl radical containing 1–20, preferably 1–10 carbon atoms, and the copolymer (A) has a glass transition temperature Tg at least -30 °C. A method for producing a multi-layer ink system using a coating composition and a multi-layer ink system are also proposed.
.
EFFECT: technical result is the provision of excellent performance properties of a multilayer paint system, obtained on the basis of the claimed composition, which does not contain non-ecological melamine resins.
