Abstract
PURPOSE: To obtain the titled laminate having improved electrical properties, by treating a base material with an amino type resin varnish containing an acidic curing agent, impregnating the base with a phenolic resin containing a flame- retardant and drying it to give prepreg, followed by laminating it.
CONSTITUTION: Preferably 0.1W1.0wt% acidic curing agent (e.g., imidodisulfonate) is added to 100pts.wt. amino type resin varnish (e.g., melamine-formaldehyde resin), and a base material (e.g., kraft paper) is subjected to the first treatment with the prepared varnish. The base material is then subjected to the second treatment with a phenolic resin containing a flame-retardant (e.g., organic phosphorus compound), impregnated with it, and dried to give prepreg. A proper number of sheets of the prepreg are piled, and molded under heating and pressure, to give the desired laminate. The coverage of the amino type resin is preferably 15W25wt% based on the base material.
