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. Such solvent-based adhesive agent may exhibit a high constant load shear peeling force and maintain good appearance for an adhesive article to which it has been applied.

Abstract: A film is described comprising a (meth)acrylic polymer and a polyvinyl acetal (e.g. butyral) resin. In some embodiments, the film has a glass transition temperature (i.e. Tg) ranging from 30° C. to 60° C. In some embodiments, the film has a gel content of at least 20% or greater. In some embodiments, the film has an elongation at break of at least 175%. The film typically comprises photoinitiator as a result of the method by which the film was made. The film may be a monolithic film or a layer of a multilayer film.
