Abstract
The present invention provides a silicone/acrylic based pressure-sensitive adhesive composition, adhesive, and adhesive tapes prepared therefrom. The adhesive composition comprises: PA1 (a) from about 5 parts to about 95 parts by weight of acrylic monomer wherein the acrylic monomer comprises: PA2 (i) from about 50 to about 100 parts by weight of alkyl acrylate monomer, the alkyl groups of which have an average of 4 to 12 carbon atoms; and PA2 (ii) correspondingly from about 50 parts to about 0 parts by weight of a monoethylenically unsaturated copolymerizable modifier monomer; PA1 wherein the amounts of (i) and (ii) are selected such that the total amount of (i) plus (ii) equals 100 parts by weight of the acrylic monomer; PA1 (b) correspondingly from about 95 parts to about 5 parts by weight of silicone pressure-sensitive adhesive wherein the amounts of (a) and (b) are selected such that the total amount of (a) plus (b) equals 100 parts by weight; PA1 (c) about 0 part to about 5 parts by weight of a photoinitiator based upon 100 parts by weight of the acrylic monomer; and PA1 (d) about 0 to about 5 part by weight of a crosslinker based upon 100 parts by weight of (a) plus (b).
