Abstract: The invention relates to a resin composition that is curable by ultra-violet light, which composition comprises(a) 10 to 99.7 percent by weight of a polyester that contains .alpha., .beta.-ethylenically unsaturated dicarboxylic acid radicals and .beta.,.gamma.-ethylenically unsaturated ether groupings, and(b) 0.3 to 10 percent by weight of a photoinitiator.

Abstract: 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.

Abstract: Unsaturated polyester resins, the polyesters of which contain 0.3 - 0.7 moles, relative to the alcohol component, of units of monohydric alcohols are outstandingly suitable for the production of cured lacquer films which are uniformly matt without matting additives when a barrier agent is used.

Abstract: Polyester moulding and coating compositions based on polyester resins of:A. from 20 to 90% by weight based on the sum of components (A) and (B), of .alpha.,.beta.-ethylenically unsaturated polyesters, andB. from 80 to 10% by weight based on the sum of components (A) and (B) of polymerizable compounds, these polyester compositions containing, in addition to possible further additives,C. from 0.1 to 8.0% by weight based on the sum of components (A) and (B) of polymerization initiators,D. from 0.001 to 0.1% by weight based on the sum of components (A) and (B) of polymerization inhibitors,E. from 0.001 to 0.5% by weight, based on the sum of components (A) and (B), of conventional accelerators,F. from 0.05 to 5.0% by weight based on the sum of components (A) and (B) of additional accelerators, and optionally,G. from 0.01 to 1.
