PCT No. PCT/EP88/01097 Sec. 371 Date Nov. 13, 1990 Sec. 102(e) Date Nov. 13, 1990 PCT Filed Dec. 2, 1988 PCT Pub. No. WO89/05314 PCT Pub. Date Jun. 15, 1989.The invention concerns a binder suitable for clear or pigmented coating agents. Binders based on copolymers containing hydroxyl groups have hitherto a high solvent content. The solids content of the new binders is improved without affecting the viscosity; gloss, body, flow and processing properties of coatings containing the new binders are improved. The binders consist essentially of a copolymer containing hydroxyl groups, made from specific quantities of styrol, tertbutacrylate, isobutyl methacrylate, 2-ethylhexyl methacrylate, 2-hydroxypropyl methacrylate, butanediol-1, 4-monoacrylate, acrylic acid and glycidyl esters of alpha -alkylalkane monocarboxylic acids and/or alpha , alpha -dialkylalkane monocarboxylic acids.
