Abstract

PURPOSE: A varnish that is prepared by adding a resol-type phenolic resin and hexamethylenetetramine to a mixture of novolak-type phenolic resin and an epoxy compound is used to make laminating with high dimesional stability and heat resistance.
CONSTITUTION: A varnish is prepared by adding 20W120pts.wt. of a resol-type phenolic resin and 1W8pts.wt. of hexamethylenetetramine to 100pts. of resin composition composed of (A) a novolak-type aromatic hydrocarbon-phenolic resin resulting from the reaction between a novolak-type phenolic resin of 200W 600 number-average molecular weight and less than 8% free phenol, an aromatic hydrocarbon-formaldehyde resin and 1W5mol (per 1 atom of oxygen in the resin) of a phenol or an oil-modified phenolic resin and of (B) an epoxy compound such as bisphenol-A where A/B is 90/10W30/70. The base material is impregnated with the resultant varnish, dried and pressed with heat.
