Abstract

PURPOSE: To improve the insulating resistance and the dielectric characteristic of the laminated plate by a method wherein, the laminated plate is turned into a prepreg through the procedure that a paper substrate is immersed with a primary varnish containing a water soluble phenol resin, further, immersed with the top coating varnish of thermosetting property to be dried.
CONSTITUTION: The primary coating varnish 7 contains as its constituent, at least, a water soluble phenol resin and water. The paper substrate 6 is travelled maintaining contact with a roll which is rotating with its lower part being immersed in the primary coating varnish 7, thereby the substrate paper is immersed with the primary coating varnish. While the immersed water soluble phenol resin is still in the state of uncured, the substrate 6 is further immersed into the top coating varnish of thermosetting property, and the prepreg is obtained after the immersed substrate is guided into a drying furnace 9 for drying. Then, the necessary number of the prepreg sheets are press heated to obtain the laminated plate. As for the solvent material for the primary coating varnish, a mixture of water with acetone, toluene, xylene, and methanol, etc. is preferable.
