The invention concerns non-aqueous paints containing a polyacrylate resin and a urea-group-containing thixotroping agent. The paints are characterized in that the polyacrylate resin can be prepared by polymerizing (a) 16 to 51 % by wt. of a hydroxy-group-containing ester of acrylic or methacrylic acid or a mixture of these monomers, (b) 32 to 84 % by wt. of an aliphatic or cycloaliphatic ester of acrylic or methacrylic acid, but different from (a), with at least 4 C-atoms in the alcohol group, or a mixture of such monomers, (c) 0 to 2 % by wt. of an ethylenically unsaturated carboxylic acid or a mixture of ethylenically unsaturated carboxylic acids and (d) 0 to 30 % by wt. of an ethylenically unsaturated monomer different from (a), (b), or (c) or a mixture of such monomers. The polyacrylate resin produced has an acid number between 0 and 15, a hydroxy number between 80 and 140 and a mean molecular weight between 1,500 and 10,000, the sum of the proportions of components (a), (b), (c) and (d) always giving 100 % by wt. |
