FIELD: automotive industry.
SUBSTANCE: invention relates to The composition for the substrate coating in the automotive industry. Disclosed is the organic solvents based pigmented coating composition, comprising from 0.1 to 1.5 wt. % of at least one copolymer (A), having Tg from -25 to 50 °C. Copolymer (A) is obtained by copolymerization of the monomers mixture (a) consisting of (a1) and (a2), where (a1) is from 10 to 60 mol. % of at least one monomer (I) (indicated in the formula), having the vinyl silane group, R1=C1-C4alkoxy, R2=C1-C4alkyl, m = 0–2; (A2) is from 40 to 90 mol. % of at least one additional olefinic unsaturated monomer. Also disclosed is the multi-layer paint coating production method using the said composition and produced by this method multi-layer coatings.
EFFECT: invention enables increase in the multilayer coating adhesion and the coating resistance to the stone impacts.
