<p>PURPOSE:To produce continuously a laminate using an unsaturated resin wherein the interlaminer strength of glass substrates is improved, by impregnating glass substrates with a blended resin liquid of an unsaturated polyester resin and an epoxy resin, and passing the resin-impregnated glass substrates together with other substrates between rolls to be formed into a laminate substrate. CONSTITUTION:Substrates 1 including at least one glass substrate are fed from each roll 2 and are dipped in each resin impregnating tank 3. Then a plurality of resin-impregnated substrates 4 that have been impregnated with the blended resin liquid are passed between rolls 5, 5 to be formed into a laminate substrate 6. Then a copper foil 8 is laminated to the laminate substrate 6, and the obtained laminate is cured by heating in a curing oven 10, then is cooled by a cooler and is cut by a cutter 12 to obtain a laminate (A) lined with copper. The weight ratio of the unsaturated resin/epoxy resin of the blended resin liquid is preferably 9/10-50/50.</p> |
