Provided are a laminating adhesive, a laminate, and a packaging material which are excellent in retorting resistance and content resistance. The adhesive includes a polyol composition (A) including a polyester polyol (A1), and a polyisocyanate composition (B) including a polyisocyanate compound (B1), in which the polyester polyol (A1) is a reaction product of a composition including a polycarboxylic acid and a polyhydric alcohol, the polycarboxylic acid including a tetramer acid. The laminate and the packaging material are produced using the adhesive.

Adhesive, laminate, and packaging material

The invention provides a packaging material that has high formability and that does not undergo a decrease in the adhesion strength between layers and appearance defects such as lifting between layers even after thermal fusion between portions of the sealant layer performed for sealing battery elements and furthermore after a long-term durability test under high temperature and high humidity. The adhesive for the packaging material including, as essential components, a polyol composition (A) and a polyisocyanate composition (B), wherein the polyol composition (A) includes a polyester polyol made from, as essential materials, a polybasic acid or its derivative and a polyhydric alcohol, the polybasic acid or its derivative material is all an aromatic-ring-containing polybasic acid or its derivative, and the polyester polyol has a number-average molecular weight in a range of 3000 to 100000; a battery packaging material, a battery container, and a battery that use the adhesive.

Adhesive for packaging material, a packaging material, and a container

Provided is a curable fluorine-containing resin produced by causing a reaction between a polymer (P) and a compound (C); the polymer (P) being prepared by copolymerization in which essential monomer components are a compound (A) having a poly(perfluoroalkylene ether) chain and styryl groups at both ends of the poly(perfluoroalkylene ether) chain and a polymerizable unsaturated monomer (B) having at least one functional group (b) selected from the group consisting of a hydroxy group, an isocyanate group, an epoxy group, a carboxyl group, an acid anhydride group, and a carboxylic acid halide group; the compound (C) having a polymerizable unsaturated group and at least one functional group (c) that has reactivity with the functional group (b) and is selected from the group consisting of a hydroxy group, an isocyanate group, an epoxy group, a carboxyl group, an acid anhydride group, and a carboxylic acid halide group.
