<p>An epoxy novolak resin which can give products of curing excellent in heat resistance, though it per se exhibits a low melt viscosity. Specifically, an epoxy novolak resin wherein the relationship between the total weight percentage of tri to hexa-nuclear components and the melt viscosity as determined by the cone and plate method at 150 °C meets specific requirements; an epoxy resin composition containing the epoxy resin; and products of curing of the composition.</p> |
