Document Type and Number:
Japanese Patent JP7014880
Kind Code:
B2
Abstract:
To provide an adhesive film in which an adhesive layer excellent in a balance of adhesive force at a low-speed peeling rate and at a high-speed peeling rate, having stain resistance and excellent adhesive performance, usable for a surface substrate each comprising TAC, PMMA and PET and having excellent antistatic performance without degradation with time can be formed from the same adhesive composition.SOLUTION: An adhesive layer is produced by crosslinking an adhesive composition containing: a first acrylic polymer having an acid number of 0.1 to 1.0 which is produced by copolymerizing without containing a polyalkylene glycol chain-containing mono(meth)acrylic acid ester monomer; a second acrylic polymer which is produced by copolymerizing a polyalkylene glycol chain-containing mono(meth)acrylic acid ester monomer; (D) a tri- or higher functional isocyanate compound; (G) an ionic compound having an anion having the number of fluorine atoms of F7 or more and having a melting point of 25 to 50°C; (E) a crosslinking retarder; and (F) a crosslinking catalyst other than a tin compound as a crosslinking catalyst.SELECTED DRAWING: None
