<p>PROBLEM TO BE SOLVED: To provide a packing material for molding without separating when a colored layer is partially cracked, even when used under a slightly severe environment such as the high temperature-high humidity, in molding time and sealing time.SOLUTION: A packing material 1 for molding is provided by laminating a heat-resistant resin layer 2, a first adhesive layer 5, a metal foil layer 4, a second adhesive layer 6 and a thermoplastic resin layer 3 on the inside from the outside, and the first adhesive layer 5 is composed of a coloring adhesive composition including a coloring pigment and an adhesive including a two-liquid curable polyester urethane resin of a polyester resin as a main agent and a multifunctional isocyanate compound as a hardening agent, and the polyester resin is 8,000-25,000 in number average molecular weight (Mn), and is 15,000-50,000 in weight average molecular weight (Mw), and these ratio (Mw/Mn) is 1.3-2.5, and the multifunctional isocyanate compound includes aromatic isocyanate of 50 mol% or more.</p> |
