Abstract: Copolymers of 23 to 92% by weight of methyl methacrylate, 5-62% by weight of an acrylic acid ester containing from 1 to 12 carbon atoms in the ester portion or a methacrylic acid ester containing from 2 to 12 carbon atoms in the ester portion and 3 to 15% by weight of unsaturated copolymerizable carboxylic acids are homogeneously mixed with triglycidyl isocyanurate, cellulose acetobutyrates and optionally with pigments and levelling agents. The mixture may be applied by electrostatic powder-spraying or other powder coating processes to suitable surfaces and cured at temperatures of about 130* to 220*C. The backed films of the mixture show outstanding adherence to the substrate and hardness coupled with elasticity, high gloss and weather resistance.
