1. An assembly comprising:
- a first substrate;
a second substrate; and
a stretch releasing pressure sensitive adhesive disposed between the first substrate and the second substrate wherein the stretch releasing pressure sensitive adhesive comprising;
a silicone pressure sensitive adhesive composition; and
a tacky tab consisting of the silicone pressure sensitive adhesive composition and is capable of being grasped and pulled, and wherein the silicone pressure sensitive adhesive composition is optically clear and comprises an elastomeric silicone polymer selected from the group consisting of urea-based silicone copolymers, oxamide-based silicone copolymers, amide-based silicone copolymers, urethane-based silicone copolymers, and mixtures thereof.

Abstract
Optically clear stretch releasing pressure sensitive adhesive films containing a silicone pressure sensitive adhesive composition and a tacky tab are provided. The pressure sensitive adhesive compositions are formed from elastomeric silicone polymer selected from the group consisting of urea-based silicone copolymers, oxamide-based silicone copolymers, amide-based silicone copolymers, urethane-based silicone copolymers, polydiorganosiloxane polymers, or mixtures of these copolymers. The pressure sensitive adhesive compositions may also contain an MQ tackifying resin. The pressure sensitive adhesive compositions may be used to form adhesive articles.
