    摘要: The present invention provides a laminate having an adhesive layer excellent in low-temperature adhesiveness, water resistance, and hot water resistance. The laminate includes: a substrate; and an adhesive layer laminated on at least one surface of the substrate, in which the adhesive layer is obtained by drying a coated product of an aqueous dispersion containing water and a resin (X), and the resin (X) contains two or more kinds of ethylene-unsaturated carboxylic acid copolymers (a) each having a different content of a structural unit derived from an unsaturated carboxylic acid.

    摘要: The purpose of the present invention is to provide a surface protection film that satisfies handling properties represented by anti-blocking properties, and various and numerous workability properties, including, favorable heat resistance and cutting properties, and the like. Provided is a surface protection film for a heating process, characterized by being formed from a compound form in which an adhesive layer (A), an intermediate layer (C), and a back layer (3) are layered in that order, the (A) layer comprising a polyethylene-based resin (a1) and a tackifier (a2) or an elastomer (a3), the (B) layer and the (C) layer each comprising a polypropylene-based resin (b) and a polypropylene-based resin (c), and the difference |ρ C -ρ A | between the density (ρ C ) of the (C) layer resin composition and the density (ρ A ) of the (A) layer resin composition and the difference |ρ C - ρ B | between the density (ρ C ) of the (C) layer resin composition and the density (ρ B ) of the (B) layer resin composition each being 0.020 g/cm 3 or less.
