    摘要: 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.

    摘要: A resinous composition comprising (a) a low-odor crosslinkable monomer obtained by reacting a glycidyl ester of synthetic or vegetable oil fatty acid with acrylic acid or methacrylic acid with heating, and (b) a polybutadiene modified by acrylic acid or methacrylic acid or an unsaturated polyester resin produces almost no or very little odor in the state of a varnish and at drying or curing. Said composition can produce varnishes excellent in mechanical and electrical properties.
