Title:
PRESSURE-SENSITIVE ADHESIVE COMPOSITION AND PRESSURE-SENSITIVE ADHESIVE SHEET MAKING USE OF THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/097365
Kind Code:
A1
Abstract:
A pressure-sensitive adhesive layer of pressure-sensitive adhesive sheet
is prepared by the use of a pressure-sensitive adhesive composition comprising
(A) polyrotaxane having a linear-chain molecule passing through opening portions
of at least two cyclic molecules, the cyclic molecules having reactive groups,
the linear-chain molecule at its both ends having block groups, and (B) adhesive
polymer having two or more functional groups capable of reacting with the reactive
groups, or a pressure-sensitive adhesive composition (A) polyrotaxane having
a linear-chain molecule passing through opening portions of at least two cyclic
molecules, the cyclic molecules having reactive groups, the linear-chain molecule
at its both ends having block groups, (B’) adhesive polymer having two
or more reactive groups and (C) compound having two or more functional groups
capable of reacting with the reactive groups of the polyrotaxane (A) and the reactive
groups of the polymer (B’). Thus, there can be provided a pressure-sensitive
adhesive sheet having a pressure-sensitive adhesive layer that excels in flexibility
and exhibits high gel ratio and durability; and provided a pressure-sensitive
adhesive composition for preparing of the pressure-sensitive adhesive layer.
