Abstract:
1. A non-aqueous, dual-cure composition comprising: a) from about 5 to about 85% by weight of a blocked (cyclo)aliphatic polyisocyanate prepared by b) from about 5 to about 85% by weight of a hydroxy-functional polymer having an OH number of from about 10 to about 250 and an acid number of from about 0.1 to about 50, with the equivalent ratio of blocked isocyanate groups to hydroxy groups being from about 0.8:1 to about 1.2:1, said hydroxy-functional polymer being selected from the group consisting of saturated polyesters, unsaturated polyesters, and mixtures thereof, c) from 0 to about 65% of an ethylenically unsaturated compound selected from the group consisting of ethylenically unsaturated monomers, polymers containing ethylenic unsaturation (other than unsaturated polyesters), and mixtures thereof and d) from about 0.1 to about 7.0% by weight of a UV initiator for free-radical polymerization,  said percentages by weight totaling 100%, and with the proviso that if ingredient b) is a saturated polyester, ingredient c) is present in an amount of from about 20 to about 65% by weight.
