    摘要: An aryl ester compound composed of a polyhydric phenol in which at least one OH group has been esterified with an organic acid or its derivatives having 1 to 20 carbon atoms, said polyhydric phenol being the condensation product of a phenolic compound represented by the general formula: 1 with a carbonyl compound represented by the general formula: 2 which aryl ester compound can give, when used as a curing agent for an epoxy resin, a cured product having a low dielectric constant and a low dielectric loss tangent; an epoxy resin composition comprising as the essential components an epoxy resin, said aryl ester compound and a cure accelerator; and a copper-clad laminate using the epoxy resin composition. The copper-clad laminate has a low dielectric constant and a low dielectric loss tangent and is excellent in adhesiveness as compared with conventional ones, and hence, is suitable for multilayer printed wiring board for high speed operation, especially at high-frequency region.
