粘着フィルム
Document Type and Number:
Japanese Patent JP7006920
Kind Code:
B2
Abstract:
To provide an adhesive film having excellent peelability, fuel oil resistance, and heat shrinkage resistance.SOLUTION: The adhesive film comprises a substrate and an adhesive layer disposed on a surface of the substrate, where the adhesive layer is formed of an adhesive composition comprising a (meth)acrylic copolymer and a crosslinking agent, and an arithmetic average roughness Ra of a surface opposite to the substrate surface is 2 μm to 15 μm. The (meth)acrylic copolymer comprises a structural unit derived from a monomer having a carboxyl group in an amount of 2 mass% to 8 mass% relative to all constituent units and a structural unit derived from an alkyl (meth)acrylate monomer having a glass transition temperature as a homopolymer of -60°C or less in an amount of 8 mass% to 50 mass% relative to all constituent units, and has a glass transition temperature of -40°C or less.SELECTED DRAWING: None
