Abstract: A silicone pressure sensitive adhesive composition is curable to form a silicone pressure sensitive adhesive. The silicone pressure sensitive adhesive composition can be coated on a substrate and cured to form a protective film. The protective film can be adhered to an anti-fingerprint coating on display glass, such as cover glass for a smartphone.

Abstract: A water-based hybrid pressure sensitive adhesive composition and a method of producing the same. The composition comprises: (A) 100 parts by mass of a siliconepressure sensitive adhesive; (B) 5 to 80 parts by mass of an acrylic pressure sensitive adhesive; (C) water in a sufficient amount to emulsify or disperse components (A) and (B) in component (C); and (D) 0.1 to 10 parts by mass of an amino-functional alkoxysilane compound, a hydrolysate thereof, or a hydrolyzed condensate thereof, wherein components (A) and (B) are emulsified or dispersed in component (C). The composition can be cured to form a pressure sensitive adhesive exhibiting good peel adhesion and low silicone migration.
