Radiation curable vinyl/silicone release coating
First Claim
1. A radiation curable release coating composition comprising:
- (a) from about 0.05 to about 25 percent by weight of polymer selected from the group consisting of polymers falling within the general formula;
##STR19## and mixtures thereof, wherein;
X are monovalent moieties having ethylenic unsaturation which can be the same or different;
Y are divalent linking groups which can be the same or different;
D are monovalent moieties which can be the same or different selected from the group consisting of hydrogen, an alkyl group of 1 to about 10 carbon atoms, and aryl;
R are divalent hydrocarbon groups which can be the same or different;
R1 are monovalent moieties which can be the same or different selected from the group consisting of alkyl and aryl;
R2 are monovalent moieties which can be the same or different selected from the group consisting of alkyl and aryl;
R3 are monovalent moieties which can be the same or different selected from the group consisting of alkyl, vinyl, and aryl;
R4 are monovalent moieties which can be the same or different selected from the group consisting of alkyl, vinyl, and aryl; and
n is an integer of about 25 to about 750;
(b) from about 5 to about 60 percent by weight of one or more multi-functional free radically polymerizable vinyl monomers copolymerizable with said polymer; and
(c) from about 25 to about 95 percent by weight of one or more monofunctional free radically polymerizable vinyl monomers copolymerizable with said polymer;
wherein said weight percentages are based upon the total weight of said radiation curable release coating composition.

Abstract
The invention relates to a radiation curable release coating composition comprising:
(a) from about 0.05 to about 25 percent by weight of polymer selected from the group consisting of polymers falling within the general formula: ##STR1## and mixtures thereof, wherein: X are monovalent moieties having ethylenic unsaturation which can be the same or different;
Y are divalent linking groups which can be the same or different;
D are monovalent moieties which can be the same or different selected from the group consisting of hydrogen, an alkyl group of 1 to about 10 carbon atoms, aryl, and substituted aryl;
R are divalent hydrocarbon groups which can be the same or different;
R1 are monovalent moieties which can be the same or different selected from the group consisting of alkyl, substituted alkyl, aryl, and substituted aryl;
R2 are monovalent moieties which can be the same or different selected from the group consisting of alkyl, substituted alkyl, aryl, and substituted aryl;
R3 are monovalent moieties which can be the same or different selected from the group consisting of alkyl, substituted alkyl, vinyl, aryl, and substituted aryl;
R4 are monovalent moieties which can be the same or different selected from the group consisting of alkyl, substituted alkyl, vinyl, aryl, and substituted aryl; and
n is an integer of about 25 to about 750;
(b) from about 5 to about 60 percent by weight of one or more free radically polymerizable multifunctional vinyl monomers copolymerizable with said polymer; and
(c) from about 25 to about 95 percent by weight of one or more free radically polymerizable monofunctional vinyl monomers copolymerizable with said polymer;
wherein said weight percentages are based upon the total weight of the radiation curable release coating composition.
The invention also relates to substrates coated with the release coating.
