    摘要: 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.
