PRESSURE-SENSITIVE ADHESIVE STRUCTURE

摘要

A pressure-sensitive adhesive structure such as a pressure-sensitive adhesive tape, label or the like having a release agent layer, wherein said release agent layer comprises a cured fluorosilicone composition comprising: (a) a particular organopolysiloxane having in its molecule silicon-bonded alkenyl groups and at least one member selected from the group consisting of silicon-bonded fluorine-containing substituents represented respectively by Formulas (1) to (4): <IMAGE> (1) where n is an integer of 1 to 5. <IMAGE> (2) where n is an integer of 1 to 5. CmF2m+1CH2CH2OCH2CH2CH2-(3) where m is an integer of 3 to 10. CmF2m+1CH2OCH2CH2CH2-(4) where m is an integer of 3 to 10. (b) an organohydrogenpolysiloxane; and (c) a catalyst, in a particular proportion. The release properties of the release agent layer show good and high stability with time, promising practical utilities over a long period of time.
