ABSTRACT:
The present invention provides a radiation curable vinyl-silicone pressure-sensitive adhesive composition which combines the advantages of silicone and acrylate pressure-sensitive adhesives and which does not experience gross phase separation problems. The composition comprises at least about 20 weight percent of a certain telechelic silicone polymer, about 0.5 to about 80 weight percent of monofunctional free-radically polymerizable vinyl monomer copolymerizable with the silicone polymer, and a sufficient amount of a silicate MQ tackifying resin to impart a degree of adhesive tack to the cured composition at the use temperature, wherein the weight percentages of the silicone polymer and the monomer are based upon the total weight of the silicone polymer and monomer.
