Abstract

PURPOSE: To obtain a laminated plate of good quality without air bubble by impregnating the base sheet with an unsaturated polyester resin liquid having dissolved air volume less than a specific value, laminating and then curing the sheets.
CONSTITUTION: A base sheet is inpregnated with an unsaturated polyester resin liquid containing less than 8ppm of, as a representative, dissolved oxygen volume of dissolved air volume at a normal temperature in liquid condition. Plurality of base sheets are laminated and a metal foil is laminated on its surface. The laminated structure is hardened to form a laminated product. In order to obtain unsaturated polyester resin containing a small volume of molten air, the following methods may be employed. (A) To use a resin material in having a small volume of dissolved air. (B) Prevent dissolution of air during synthesizing process or after the process, (C) Prevent dissolution of air during addition of hardening catalyst and assistant agent, etc. and (D) Carry-out a pressure reducing treatment when the product is used.
