Abstract

Baking finishes having a high solids content contain, as the binder, a copolymer of one or more mono-acrylate or monomethacrylate of an alkanediol, an ester of acrylic or methacrylic acid whose homopolymer has a glass transition temperature of below -40.degree. C., an ester of acrylic acid or methacrylic acid whose homopolymer has a glass transition temperature of above 35.degree. C. and acrylic acid or methacrylic acid, which copolymer has a Fikentscher K value of from 13 to 17 and may or may not be used in combination with conventional aminoplast precondensates having a crosslinking action. These baking finishes are particularly useful as binders for automotive finishes.
