<p>CROSS-LINKABLE POLYMER RESINS AND USE THEREOF AS BINDERS FOR COATING AGENTS The present invention is directed to crosslinkable, hydroxyl group-containing polymer resins which are obtained by copolymerizing olefinicallyunsaturated monomers and are suitable as binder components for lacquers, the polymer resins having a hydroxyl number of about 20 to 400, an average osmometrically-determined molecular weight of about 500 to 30,000 and a molecular inhomogeneity U of about 0.5 to 15, characterized in that they contain about 0.2 to 80 by weight, preferably about 10 to 70% by weight, based on the total weight of the copolymers, of incorporated monomers selected from olefinically- and acetylenically-unsaturated aliphatic diols having 4 carbon atoms, the ether group-containing alkoxylation products thereof with a hydroxyl number of about 50 to 900, the reaction products of these diols with .epsilon.-caprolactone in a mol ratio of diol: -caprolactone of about 1:0.2 to 1:10 and any mixtures of these components. The present invention is also directed to the use of the above polymer resins as binders for coating compositions.</p> |
