Abstract
(EN)
The purpose of the present invention is to provide an adhesive composition that is capable of maintaining the transparency of an object to which a surface protective film is bonded even under high temperature high humidity conditions, while maintaining adequate curability even in cases where the film thickness is small. An adhesive composition according to the present invention contains (A) a urethane resin, (B) a curing agent and (C) a phosphorus curing accelerator, and is characterized in that: the urethane resin (A) has an acid group; the curing agent (B) contains an epoxy curing agent that has two or more epoxy groups in each molecule and an isocyanate curing agent that has two or more isocyanate groups in each molecule; and the phosphorus curing accelerator (C) is composed of a phosphonium salt.

La présente invention a pour objet de fournir une composition adhésive qui est apte à maintenir la transparence d'un objet auquel un film de protection de surface est lié même dans des conditions de température élevée et d'humidité élevée, tout en conservant une aptitude au durcissement adéquate même dans les cas où l'épaisseur du film est faible. Une composition adhésive selon la présente invention contient (A) une résine d'uréthane, (B) un agent de durcissement et (C) un accélérateur de durcissement au phosphore, et est caractérisée en ce que : la résine d'uréthane (A) comprend un groupe acide ; l'agent de durcissement (B) contient un agent de durcissement époxyde qui comprend deux groupes époxy ou plus dans chaque molécule et un agent de durcissement isocyanate qui comprend deux groupes isocyanate ou plus dans chaque molécule ; et l'accélérateur de durcissement au phosphore (C) est composé d'un sel de phosphonium.
