Abstract
PURPOSE: To prepare a laminated sheet having uniform qualities and improved punchability, economically by using a resol-type phenolic resin varnish containing a specific compound as a plasticizer.
CONSTITUTION: An impregnating varnish is prepared by compounding a phenolic resin varnish with a compound having polyethylene glycol (n<50) units in the main chain and phenolic nucleus at the both ends of the chain, e.g. expressed by the formula. A phenolic resin laminated sheet useful as printed circuit board, etc. is prepared by laminating a plurality of substrates impregnated with the above varnish.
