Laminate with ultra=violet control of release between pressure-sensitive adhesive and release film

摘要

A laminate of a pressure-sensitive adhesive film (A) in contact with a first release film (R1), in which the adhesive strength between (A) and (R1) increases when the interface between them is exposed to ultraviolet (UV) light. Also claimed are methods of (a) increasing the peel strength between (A) and a silicone film by exposing the interface to UV light; and (b) producing a UV signature.
