PROBLEM TO BE SOLVED: To provide a method of improving tackiness and blocking resistance of an undercoat layer of a thin film metal layer formed during a process of a manufacturing method of a laminate exhibiting iris color, and to provide a coating material composition for the undercoat layer suitable for the method.SOLUTION: A coating material composition for forming an undercoat layer of a think film metal layer contains (A) an urethane (meth)acrylate compound obtained by reacting (a1) a diisocyanate compound and (a2) hydroxyl group-containing (meth)acrylic acid ester with polyester diol of 35 to 55 mass%, (B) a compound having 2 or more radical polymerizable double bonds in a molecule of 45 to 65 mass%, (D) a compound having a radical polymerizable double bound in the molecule of 0 to 5 mass% and (C) a photoinitiator. There is also provided a method of manufacturing a laminate by coating a base material with the composition, curing the obtained coated film to form an undercoat layer, and forming a thin film metal layer by vapor deposition on the undercoat layer. |
