Abstract
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: <IMAGE> wherein R is H or CH3, R1 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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
130 words
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 3 , R 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 1 and R 3 are members independently selected from the group consisting of substituted and unsubstituted aromatic radicals, R 2 and R 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.
Claim 2
Dependent Claim
130 words
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 3 , R 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 1 and R 3 are members independently selected from the group consisting of substituted and unsubstituted aromatic radicals, R 2 and R 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.
