ABSTRACT OF THE DISCLOSURE A nitrogen-containing acrylic copolymer composition comprising: (i) a linear copolymer comprising about 2 to about 90 % by weight of recurring units of Formula (A), Image (A) wherein R1 and R2, which may be the same or different, each represents a hydrogen atom, a C1-20 alkyl group, a C3-10 cycloalkyl group, a C3-8 alkenyl group, a C1-15 aminoalkyl group, a C6-20 aryl group or a C7-12 arylalkyl group, based on the total weight of the linear copolymer, about 10 to about 98 % by weight of recurring units of formula (B) (B) Image wherein R3 represents a hydrogen atom, a methyl group, a C1-6 alkoxy group, a halogen atom or a -CH2COOR6, group wherein R6 represents a hydrogen atom, a C1-10 alkyl group or a C7-12 arylalkyl group, R4 represents a hydrogen atom, a C1-20 alkyl group. a C3-10 cycloalkyl group, a C3-10 halocycloalkyl group, a C6-20 aryl group, a C6-20 haloaryl group, a C7-12 arylalkyl group, a C1-12 haloalkyl group, a C1-12 hydroxyalkyl group, a C2-12 alkoxyalkyl group, a tetrahydrofurfuryl group, a glycidyl group, a ?CH2-CH2-O ? R7, wherein R7 is a C1-8 alkyl group and m is an integer of 1 to 30, or a C3-20 dialkylaminoalkyl group, and R5 represents a hydrogen atom or a -COOR8 group wherein R8 is a hydrogen atom or a C1-20 alkyl group, based on the total weight of the linear copolymer and 0 to about 88 % by weight of recurring units of at least one of Formulae (C1) ), (C2) and (C3), Image (C1) (C2) Image (C3) wherein V and W each independently is a hydrogen atom, a C1-8 alkyl group, a phenyl group or a halogen atom, based on the total weight of the linear copolymer, (ii) about 0.1 to about 10 % by weight of an amine-modified epoxy compound where all or part of the epoxy group has been replaced by the unit of Formula (I), Image (I) wherein R12 and R13 each independently is a hydrogen atom, a C1-20 alkyl group, a C3-10 cycloalkyl group, a C1-12 hydroxyalkyl group, a C1-15 aminoalkyl group, a H?NH-CH2-CH2? wherein n is an integer of 1 to 8, a C6-15 aryl group or a C7-12 arylalkyl group, based on the weight of the linear copolymer and (iii) about 0.05 to about 12 % by weight of a blocked polyisocyanate where all or part of the isocyanate groups has been replaced by an alcohol and/or an amine, based on the weight of the linear copolymer.
