RESIN IMPREGNATED SUBSTRATE, ITS PRODUCTION, LAMINATED SHEET AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a resin impregnated material by which the resin impregnated material good in impregnating properties of a substrate with a resin can stably be obtained. SOLUTION: A substrate 1 is previously impregnated with an organic solvent at >=30 deg.C, then impregnated with a resin varnish 3 and subsequently dried. Since the substrate 1 is impregnated with the organic solvent 2 without unevenness and further impregnated with the resin varnish 3, the impregnation of the resin varnish 3 can be carried out without causing an unimpregnated part in the substrate 1.
