Patent ID: 7005475

Claim:
An aqueous emulsion including a curable composition comprising (A) additives for improved anchorage of pressure sensitive adhesive coatings comprising: (R a SiO (4-a)/2 ) n where n is an integer greater than 3, a is from 1 to 3, R is a silicon-hydride, an alkylenealkoxysilyl containing radical having from one to forty carbon atoms, or a monovalent hydrocarbon or hydrocarbonoxy radicals, with at least one silicon-hydride and one alkylenealkoxysilyl containing radical being present on the molecule and (B) a curable alkenyl silicone having the formula M vi a T b D c M d where M vi =R 1 3-p R 2 p SiO 1/2 , where R 1 is selected from the group consisting of one to forty carbon monovalent hydrocarbon radicals and R 2 is selected from the group consisting of two to forty carbon atom terminal olefinic monovalent hydrocarbon radicals, where p ranges from 1 to 3; T=R 3 SiO 3/2 , where R 3 is selected from the group consisting of R 1 and R 2 ; D=R 4 R 5 SiO 2/2 where R 4 and R 5 are each independently selected from the group consisting of R 1 and R 2 ; and M=R 1 3 SiO 1/2 where each R 1 is as previously defined and is independently selected; wherein a and b have values ranging from 2 to 5, c is an integer ranging from about 50 to about 1,000 and d has a value ranging from 0 to about 0.5.
