    摘要： The present invention relates to a copolymer (A) having a glass transition temperature Tg of at least -30°C, which can be obtained by the copolymerization of a mixture of olefinically unsaturated monomers (a) in at least one organic solvent and in the presence of at least one initiator, wherein the mixture of monomers (a) (a1) to be polymerized comprises 10 to 60 mol % of at least one monomer of the following formula (I) with R
    1 = C
    1 - to C
    4 -alkoxy, R
    2 = C
    1 - to C
    4 -alkyl and m = 0 to 2, and (a2) 40 to 90 mol % of at least one olefinically unsaturated monomer selected from the group formed by monomers of formulas H
    2 C=CH

    摘要： [Problem] To provide a paint composition which forms paint films which are excellent in terms of car-wash scratching resistance, acid resistance and weather resistance, a method of finish painting and painted objects. [Means of Resolution] A paint composition which has as essential components hydroxyl group containing resin (A) which has a hydroxyl group value of from 80 to 220 mgKOH/g, a glass transition temperature of -50°C or above but below 0°C and which contains from 25 to 55 mass% of units of 4-hydroxybutyl (meth)acrylate origin, hydroxyl group containing resin (B) which has a hydroxyl group value of from 80 to 220 mgKOH/g and a glass transition temperature of from 0 to 50°C and crosslinking agent (C) comprising polyisocyanate compound, characterized in that the proportions of hydroxyl group containing resin (A) and hydroxyl group containing resin (B) included are, as a ratio of the solid fraction masses, from 95/5 to 50/50, and the proportion of isocyanate groups which are the functional groups of the crosslinking agent (C) included with respect to the hydroxyl groups in total of the hydroxyl group containing resin (A) and the hydroxyl group containing resin (B), as the NCO/OH mol ratio, is from 0.5 to 1.5.
