Abstract
This invention is directed to dual UV and heat activated compositions comprising (1) a liquid, ethylenically unsaturated monomer, oligomer or prepolymer of the formula: ##STR1## wherein R is H or CH.sub.3, R.sub.1 is an organic moiety and n is 2 to 4, hereinafter referred to as the ethylenically unsaturated compound, (2) a photoinitiator, and (3) a substituted or unsubstituted pinacol The exposure to UV radiation and heat in seriatim or simultaneously results in a cured solid product which can be utilized as coatings, gaskets, sealants, resists and the like.

A dual UV radiation and heat activitable composition consisting essentially of
- (1) a liquid ethylenically unsaturated compound of the formula:
- ##STR6## wherein R is H or CH.sub.3, R.sub.1 is an organic moiety and n is 2 to 4, (2) 0.0005 to 30% by weight of (1) of a photoinitiator, and
- (3) 0.01 to 5% by weight of (1) of a substituted or unsubstituted pinacol of the general formula:
- ##STR7## wherein R.sub.1 and R.sub.3 are members independently selected from the group consisting of substituted and unsubstituted aromatic radicals, R.sub.2 and R.sub.4 are members independently selected from the group consisting of substituted and unsubstituted aliphatic and aromatic radicals and X and Y are members independently selected from the group consisting of hydroxyl, alkoxy and aryloxy.

- (1) a liquid ethylenically unsaturated compound of the formula:
- ##STR8## wherein R is H or CH.sub.3, R.sub.1 is an organic moiety and n is 2 to 4, (2) 0.0005 to 30% by weight of (1) of a photoinitiator,
- (3) 0.01 to 5% by weight of (1) of a substituted or unsubstituted pinacol of the general formula:
