(12) 2. Preparation of Layered Product for Evaluation

(13) The coating material composition prepared in the above section 1 was spray-coated to a surface of a rectangular plate test piece made of BMC having a size of length 9 cm, width 5 cm, and thickness 3 mm serving as a base material such that the film thickness of the coating film after curing became about 20 μm.

(14) Next, the organic solvent content was volatilized by performing heat treatment at a temperature of 60° C. for 3 minutes in an oven. Thereafter, the coating film was cured in air using a high-pressure mercury lamp by irradiation of ultraviolet rays having an integrated quantity of light of 2000 mJ/cm.sup.2 from the upper side of the coated surface. In measurement of the quantity of light, the integrated quantity of energy of ultraviolet rays with a wavelength of 340 nm to 380 nm was measured using UV-351 (SN type) (trade name, manufactured by ORC MANUFACTURING CO., LTD.) as an actinometer. Subsequently, aluminum was vapor-deposited on the cured film (undercoat layer) by a vacuum deposition method using a vacuum deposition apparatus (manufactured by ULVAC, Inc., trade name: EBA-800) such that the film thickness became about 20 nm, thereby forming an aluminum vapor deposition film. Further, an acryl-melamine curable clear coating material (manufactured by Mitsubishi Rayon Co., Ltd., trade name: Diabeam UT-047A) was spray-coated on the aluminum vapor deposition film for the purpose of corrosion prevention of the aluminum vapor deposition film and the like such that the film thickness after curing became 5 μm, and the coating material was then cured by performing heat treatment under conditions of a temperature of 120° C. for 10 minutes, thereby forming a topcoat layer. In this way, a layered product for evaluation having three coating layers formed on the surface of the base material was prepared.

(48) From the above-described Examples, it is found out that according to the actinic-ray-curable coating material composition of the invention, an undercoat layer for metallic vapor deposition, which is excellent in adhesion to various base materials, adhesion to a metallic vapor deposition film, appearance, and heat resistance, can be provided. In Comparative Example 1, since the component C was not used, adhesion of the coating film to BMC was not sufficient. In Comparative Example 2, since the amount of the component C used was large, adhesion of the coating film after the heat resistance test to PPS was not sufficient. In Comparative Example 3, since the amount of the component A used was large, appearance at the initial stage and appearance after the heat resistance test of the coating film were not sufficient. In Comparative Example 4, since the amount of the component A used was small, adhesion of the coating film was not sufficient. In Comparative Example 5, since the component A was not used, appearance of the coating film was not sufficient. In Comparative Example 6, since the component A was not used, appearance of the coating film to PPS and the PBT/PET alloy was not sufficient. In Comparative Example 7, since the component C was not used, adhesion of the coating film to the PPS base material and the PBT/PET base material was not sufficient. In Comparative Example 8, since the amount of the component A used was large, appearance at the initial stage and appearance after the heat resistance test of the coating film were not sufficient. In Comparative Example 9, since the amount of the component A used is small, adhesion of the coating film to the BMC base material was not sufficient.
