Japanese Patent JP7416599
Kind Code:
B2
Abstract:
A transparent solvent-based acrylic pressure-sensitive adhesive agent is described. Such agent contains: an adhesive (meth)acrylic polymer having a weight average molecular weight of 350000 or less; a high Tg (meth)acrylic polymer having a glass transition temperature of 40° C. or higher; a covalent bonding crosslinking agent that can form a covalent bond with the adhesive (meth)acrylic polymer; and at least one type of non-covalent bonding crosslinking agent selected from the group consisting of a benzotriazole compound, a piperidyl compound having at least two piperidyl groups, and an aluminum chelate compounds.
