To provide a pressure-sensitive adhesive optical film in which an adhesive layer is stacked on an optical film, and which has durability and can suppress irregular display in a peripheral part of a display screen particularly in storing at high temperature.
In the adhesive optical film in which the adhesive layer is stacked on an optical film, the adhesive layer contains a polyurethane polymer (A), as a base polymer, obtained by allowing a polyol compound (a-1) having a weight average molecular weight of 500-4,000, an isocyanate compound (a-2), a polyamino compound (a-3) having no hydroxyl group as a chain extender, and a polyol compound (a-4) having two or more radical polymerizable C=C bonds in one molecule to react with each other, and the pressure-sensitive adhesive layer contains 0.01-0.5 part by weight of a silane coupling agent (B) based on 100 parts by weight of the urethane polymer (A).
