Abstract

Poly(meth)acrylate dispersions, comprised of: (A) 50-90 wt. % methacrylic acid esters; (B) 5-30 wt. % acrylic acid alkyl esters, [lit., "acrylic acid acrylic esters"]; (C) 2-10 wt. % of another functionalized monomer; (D) 2-10 wt. % of a radically polymerizable carboxylic acid or a polycarboxylic acid or a partially esterified polycarboxylic acid; and (E) 0-40 wt. % of a monomer which is copolymerizable with components (A) to (D).
