Abstract

PURPOSE: To obtain a phenolic resin modified so as to provide a laminated plate with flexibility, by blending phenolic resin with a compound obtained through addition of a phnolic nucleus to polyethylene glycol and a cyclic terpene phenol.
CONSTITUTION: A) A compound obtained by adding a phenolic nucleus to at least one end of a main chain consisting of a skeleton, e.g., polyethylene glycol and B) a cyclic terpene phenol are added to phenolic resin during and/or after production of a resol type phenolic resin or phenolic resin varnish. An amount of the compound A is preferably 50W200g based on one gram mole of phenol in the production of the resol type phenolic resin or one gram mole of phenol in the production of the resol type phenolic resin which is a raw material of phenolic resin varnish. A weight ratio of A) to B) is preferably 1/10W10/1.
