A dyestuff acceptor for synthetic resins such as polyvinyl chloride comprises as essential components (A) a copolymer of at least one ethylenically unsaturated monomer and an aminoalkyl acrylate compound represented by the general formula, ##STR1## wherein R.sub.I represents hydrogen or methyl group, R.sub.II and R.sub.III represent hydrogen or alkyl groups having 1 to 4 carbon atoms, and n represents an integer from 1 to 4, and (B) a compound of a polyvalent metal selected from silicon, nickel, tin, cobalt, and iron, having at least one functional group selected from the group consisting of carboxyl group, thioalkoxy groups, alkyl groups, phenyl groups, and cyclopentadienyl group, the weight ratio of said component (A) to said component (B) being about 100 : 1 to 1 : 1.
A dyestuff acceptor of synthetic resins, comprising as essential components (A) a copolymer comprising about 20 to 99 mole % of at least one ethylenically unsaturated monomer which is not an aminoalkyl acrylate compound and about 1 to 80 mole % of an aminoalkyl acrylate compound represented by the formula, ##STR4## wherein R.sub.I is hydrogen or methyl, R.sub.II and R.sub.III each are hydrogen or alkyl having 1 to 4 carbon atoms, and n is an integer from 1 to 4, and (B) a compound of a polyvalent element selected from silicon and tin, having at least one functional group selected from the group consisting of carboxyl, thioalkoxy, alkyl, phenyl and cyclopentadienyl, the weight ratio of said component (A) to said component (B) being about 100:1 to 1:1.
