Abstract
A water-reducible mixture of (meth)acrylic copolymers having a hydroxyl number of from 40 mg/g to 250 mg/g, an acid number of from 15 mg/g to 80 mg/g, a weight average molar mass Mfrom 9 kg/mol to 40 kg/mol and a glass transition temperature Tfrom −40° C. to 80° C., based on polymerised monomers comprising at least one alkyl ester A of an olefinically un-saturated carboxylic acid having from 1 to 8 carbon atoms in the alkyl group, at least one hydroxy functional alkyl ester B of an olefinically unsaturated carboxylic acid, at least one aliphatic compound C that has both hydroxy and carboxyl functionalities, or which is a lactone or a cyclic lactone, at least one vinyl monomer D which does not comprise a moiety derived from an olefinically unsaturated carboxylic acid, at least one olefinically unsaturated carboxylic acid E, a process for its preparation, and a method of use thereof in the preparation of paints.
