Abstract

A reaction product of an acrylate resin containing glycidyl groups and secondary mono-amines containing hydroxyl groups, obtained by reacting of said acrylate resin of copolymerized, statistically distributed units of PA1 (A) 3 to 30% by weight of the glycidyl ester of (meth)acrylic acid and/or of vinyl glycidyl ether; PA1 (B) 0 to 20% by weight of at least a hydroxy C.sub.2 -C.sub.4 alkyl ester of (meth)acrylic acid; PA1 (C) 5 to 80% by weight of at least an optionally substituted styrene, methyl methacrylate, (meth)acrylonitrile or any mixture thereof; PA1 (D) 5 to 70% by weight of an acrylic acid C.sub.1 -C.sub.12 -alkyl-or of a methacrylic acid C.sub.2 -C.sub.12 -alkyl ester or any mixture thereof; and PA1 (E) 0 to 10% by weight of an .alpha.,.beta.-mono-olefinically unsaturated monocarboxylic or dicarboxylic acid containing from 3 to 5 carbon atoms or of a maleic acid C.sub.2 -C.sub.14 -mono ester or any mixture thereof, with at least one secondary mono-amine containing at least one secondary hydroxyl group. The reaction products are useful for crosslinking polyisocyanates.
