    • A coating composition comprising as binder a reaction product of a polyepoxide with more than one 1,2-epoxide group per molecule, wherein its epoxide groups have been reactedA. with 0.01 to 0.5 NH-equivalents, based on one epoxide equivalent, of ammonia or of an aliphatic or cycloaliphatic primary or secondary amine or of an amino carboxylic acid or of a mixture of the aforementioned nitrogen compounds; and subsequentlyB. with 0.40 to 0.90 carboxyl equivalents, based on one epoxide equivalent, of acrylic acid or methacrylic acid or of a mixture of acrylic amd methacrylic acid; and finallyC. with 0.09 to 0.50 carboxyl equivalents, based on one epoxide group, of a saturated aliphatic, a cycloaliphatic or an aromatic carboxylic acid, so that at least 80% of the epoxide groups originally present have been reacted through these three component stages. The binder may be used alone or together with additional monomers by radicals forming compounds or preferably by photopolymerization in the presence of a photoinitiator.
    • 一种涂料组合物,其包含作为粘合剂的每分子具有多于一个1,2-环氧基团的聚环氧化物的反应产物,其中其环氧基团已经与A反应。以0.01至0.5NN当量,基于一个环氧当量的氨 或脂族或脂环族伯胺或仲胺或氨基羧酸或上述氮化合物的混合物; 随后用0.40至0.90羧基等同物,基于一种环氧化物等同物,丙烯酸或甲基丙烯酸或丙烯酸AMD甲基丙烯酸混合物; 和最终C.与0.09至0.50碳羧基等同物,基于一个环氧化物组,饱和脂肪酸,环己醇或芳香羧酸,因此至少80%的环氧化物原料通过这三个组分阶段反应 。 粘合剂可以单独使用或与另外的单体一起通过自由基形成化合物使用,或者优选在光引发剂的存在下通过光聚合使用。
