Abstract

A binder composition which has a number average molecular weight of from 1000 to 20,000 and which comprises, in copolymerized form, from 5 to 55% by weight of fumaric acid and/or maleic acid bis-glycidyl ester and from 95 to 45% by weight of one or more vinyl and/or vinylidene monomers, esterified to an acid number of from 3 to 30 mg KOH/g with from 18 to 72% by weight, based on copolymer plus fatty acid, of a fatty acid and subsequently reacted with 0 to 3% by weight, based on copolymer plus fatty acid plus dicarboxylic acid anhydride, of a dicarboxylic acid anhydride.
