ABSTRACT:
A thermosetting resin composition is derived from a modified novolak-type resin obtained by the reaction of a phenolic compound with an aralkyl halide or ether. The thermosetting resin is composed of 20 to 80 parts by weight of a thermosetting resin prepared by reacting a modified novolak-type resin represented by, for example, the general formula, ##SPC1##
Wherein R is an aromatic nucleus, with formaldehyde in the presence of a basic catalyst, and, in admixture therewith, 80 to 20 parts by weight of a thermosetting resin prepared by reacting the above-mentioned modified novolak-type resin with hexamethylenetetramine. The thermosetting resin is quickly curable and gives a cured article excellent in heat resistance.
