Abstract
Abstract An improved ultraviolet curable coating composition particularly useful with titanium dioxide pigmented systems is disclosed containing about 5 to about 85 percent, by weight, based on the total ultraviolet curable composition, of an alpha beta ethylenically unsaturated vinyl polymerizable compound containing at least about 2 sites of alpha beta ethylenic unsaturation, up to about 50 percent, by weight, of an alpha beta ethylenically unsaturated vinyl polymerizable compound containing a single site of alpha beta ethylenic unsaturation, about 0.05 to about 15 percent, by weight, on the same basis, of an ultraviolet photoinitiator, and about 5 to about 50 percent, by weight, of a polyacrylate or methacrylate ester of a polyhalogenated polyol.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
98 words
In an ultraviolet curable coating composition containing about 5 to about 85 percent, by weight, based upon the total composition, of an alpha beta ethylenically unsaturated vinyl polymerizable compound containing at least 2 sites of alpha beta ethylenic unsaturation, up to about 50 percent, on the same basis, of another alpha beta ethylenically unsaturated vinyl polymerizable monomer containing a single site of alpha beta ethylenic unsaturation, and about 0.05 to about 15 percent, by weight, of an ultraviolet photoinitiator, the improvement of which comprises utilizing as a reactive comonomer a polyacrylate or methacrylate ester of a polyhalogenated polyol.
Claim 2
Dependent Claim
98 words
In an ultraviolet curable coating composition containing about 5 to about 85 percent, by weight, based upon the total composition, of an alpha beta ethylenically unsaturated vinyl polymerizable compound containing at least 2 sites of alpha beta ethylenic unsaturation, up to about 50 percent, on the same basis, of another alpha beta ethylenically unsaturated vinyl polymerizable monomer containing a single site of alpha beta ethylenic unsaturation, and about 0.05 to about 15 percent, by weight, of an ultraviolet photoinitiator, the improvement of which comprises utilizing as a reactive comonomer a polyacrylate or methacrylate ester of a polyhalogenated polyol.
Claim 3
Dependent Claim
14 words

Claim 8
Dependent Claim
12 words
The composition of claim 2 in admixture with a titanium dioxide pigment.
Claim 9
Dependent Claim
