Title:
DECORATION OF FIBER-REINFORCED PLASTIC MATERIAL
Document Type and Number:
Japanese Patent JPS5818288
Kind Code:
A
Abstract:

PURPOSE: To obtain a fiber-reinforced plastic molding having excellent pattern adhesion by a method in which a pattern is formed on a releasing supporter by using an ink containing epoxy resin, acrylate monomer, and a curing agent and then exposed to irradiation of electron rays to obtain a transfer paper, and the transfer paper is lapped on a resin-impregnated pre-preg and hot-pressed and the supporter is removed.

CONSTITUTION: A releasing supporter (e.g., of a polyolefinic resin, etc.) is printed by a gravure by using an ink, obtained mixing an epoxy resin (e.g., of diglycidylether series, etc.), an acrylate monomer (e.g., ethyleneglycol diacrylate, etc.), and a curing agent (e.g., an aliphatic amine, etc.) for the epoxy resin, and then exposed to the irradiation of electron rays for precuring to obtain a transfer paper. Then, the transfer paper is lapped with an epoxy resin-impregnated pre- preg in such a way as to make it contact with the printing face of the transfer paper and hot-pressed at 150W180°C and 10W100kg/dl preferably, and then the releasing supporter is removed. Thus, a plastic molding whose surface is integrally bonded with a pattern can be obtained.
