Abstract
Abstract A new composition of matter particularly useful as a diluent in ultraviolet coating compositions is disclosed, having the formulae : ##STR1## wherein R is --CH 3 or --CH 2 CH 3 , R' is hydrogen, C 1 -C 3 alkyl or C 1 -C 3 halogenated alkyl, R" is hydrogen or methyl, and n is 1-4.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
129 words
An ultraviolet curable coating composition containing, based on total composition weight, between about 40 and 97.5 weight percent of an alpha beta ethylenically unsaturated vinyl polymerizable compound containing at least about two vinyl polymerizable groups per molecule; between about 0 and 57.5 weight percent of an alpha beta ethylenically unsaturated vinyl polymerizable compound containing a single vinyl polymerizable group; an ultraviolet photoinitiator; and between about 2.5 and 60 percent of a comonomer diluent having low viscosity and extremely low volatility and excellent cure response, wherein the said comonomer diluent corresponds to the formula: ##STR12## where R is --CH 3 or --CH 2 CH 3 ; R' is hydrogen, C 1 -C 3 alkyl or C 1 -C 3 halogenated alkyl; R" is hydrogen or methyl; and n is 1-4.
Claim 2
Dependent Claim
129 words
