Document Type and Number:
Japanese Patent JP6856394
Kind Code:
B2
Abstract:
The present invention relates to an adhesive composition, an adhesive layer, a surface protective film, and an optical member. The present invention provides an adhesive composition, a pressure-sensitive adhesive layer obtained by crosslinking the pressure-sensitive adhesive composition, a surface protective film obtained by forming a pressure-sensitive adhesive layer on a support, and an optical member protected by a surface protection film. The adhesive composition has a long pot life, a high cross-linking property (degree of crosslinking) after the curing treatment of the adhesive composition and the aging treatment, and a small change in the color tone of the adhesive layer, and can prevent the adhesive strength of the pressure-sensitive adhesive layer from being increased after adhered and stored. The adhesive composition of the present invention is characterized in that , with respect to 100 parts by mass of the polymer (A) having an active hydrogen functional group, the adhesive composition contains an isocyanate-based crosslinking agent (B), 0.001~0.4 by mass of the compound (C) having tin as an active center and 0.001~0.4 parts by mass of the compound (D) having iron as an active center.
