Abstract
PURPOSE: To obtain the captioned laminated sheet where a copper foil and a core layer are adhered together in satisfactory condition by providing a photosetting resin layer on an unsaturated polyester core layer surface, laminating an epoxy resin- impregnated prepreg and a metal foil after light irradiation and hot-pressing the laminated layers.
CONSTITUTION: An unsaturated polyester resin, a cross linking agent, a photopolymerization initiater, an inorganic filler, etc. are mixed and pressed into a sheet of unsaturated polyester core layer 1. Then on the both sides of said layer 1, a photosetting resin layer 2 of photosetting unsaturated polyester resin and/or cpoxy acrylate resin containing a cross linking agent, a photopolymerization initiater, etc. is provided preferably in a thickness of less than 50μ. Next, an ultraviolet ray is irradiated using a light source such as mercury lamp, etc., so that the resin components of the both layers 2, 1 are brought into a stage "B". Following this process, an epoxy resin-impregnated prepreg is laminated on the both sides as a subliner 3 and further a copper foil 4 is laminated on the subliner 3 provided to the both sides to be formed under thermal pressure.
