PRESSURE SENSITIVE ADHESIVE COMPOSITION, PRESSURE SENSITIVE ADHESIVE SHEET, PRESSURE SENSITIVE ADHESIVE FILM, LAMINATE FOR TOUCH PANEL, AND CAPACITIVE TOUCH PANEL

摘要

The present invention provides a pressure sensitive adhesive composition capable of forming a pressure sensitive adhesive sheet which has excellent adhesiveness and a low relative permittivity and causes less change in the relative permittivity according to environmental temperatures, a pressure sensitive adhesive sheet, a pressure sensitive adhesive film, a laminate for a touch panel including the pressure sensitive adhesive sheet, and a capacitive touch panel.;The pressure sensitive adhesive composition of the present invention includes: a component selected from the group consisting of a polymer obtained by polymerizing a monomer component including 5 to 75 mass % of a monomer having a nitrogen atom-containing cyclic structure and 25 to 80 mass % of a (meth)acrylic monomer having an alkyl group with 3 to 22 carbon atoms at an ester end, a product of partial polymerization of the monomer component, and the monomer component; and at least one rubber component selected from the group consisting of polyisoprene, polyisobutylene, and polybutadiene, in which the content of the rubber component is 1 to 50 mass % with respect to a total solid content.
