Abstract

PURPOSE: To manufacture the title laminated sheet having excellent flame resistance, electrical properties, impact resistance, and moisture resistance, in a single immersion process, by impregnating a substrate with a mixture of a modified phenolic resin and a specific butylphenolic resin.
CONSTITUTION: A substrate such as kraft paper is impregnated with a mixture of (A) 80W97 parts by weight (dry basis) of a modified phenolic resin obtained, e.g. by the condensation reaction of a mixture of phenol, tung oil, and ethylphenol, etc., with formaldehyde, and (B) 20W3 parts by weight of a butylphenolic resin having 3 or less nuclei. After drying the varnish, the impregnated sheets are stacked together, and hot pressed to obtain the objective laminated sheet.
