Reaktionsschritte

To a monomeric mixture of the formulation shown in Table 8 were added 10 g of tert-butyl perbenzoate and 30 g of azobisbutyronitrile. The mixture was then added dropwise over the course of 4 hours to 1,000 ml of toluene heated at 100° C. The reaction was further continued for 10 hours at 100° C, and then the toluene was removed to provide an acrylic copolymer resin having a number average molecular weight of about 20,000 and an oxirane group content of 2,150 g·eq/106 g and a softening point of 110° C. Powder paints were prepared in the same way as in Example 1 except that the polyester and the acrylic resin in the amounts shown in Table 9 were used instead of the polyester A and triglycidyl isocyanurate. The powder paints were coated, and baked at a temperature of 200° C for 30 minutes. The resulting coatings had a film thickness of 60 to 65μ and the properties shown in Table 10.
