Resin composition, a sheet, a prepreg-like material using the same, with the metal foil sheets, laminates, electrically insulating materials, and resist materials

摘要

PROBLEM TO BE SOLVED: To provide a resin composition with high heat resistance and high dielectric constant and low dielectric loss tangent in high-frequency region, and to provide sheets, prepreg-like materials, metallic foil-clad sheets, laminated boards, electrical insulation materials and resist materials each using the resin composition.;SOLUTION: The resin composition comprises a polyester, an epoxy resin, a curing promoter and dielectric powder, wherein the polyester is composed of an aromatic polycaroxylic acid residue having an aryloxycarbonyl group or arylcarbonyloxy group on the molecular chain end and an aromatic polyhydroxy compound residue. This resin composition has a dielectric constant of at least 4 and a Q-value of at least 250.;COPYRIGHT: (C)2006,JPO&NCIPI
