Patent number: 9120293Abstract: A preliminary-cured material permits reduced surface roughness of a roughening-treated surface, and increase of an adhesive strength between a cured object and a metal layer. The preliminary-cured material is obtained by advancing curing of an epoxy resin material that contains an epoxy resin, a curing agent, and a silica. The preliminary-cured material includes a first principal surface to be roughening-treated, and a second principal surface. The silica includes a first small particle-diameter silica whose particle diameter is not smaller than 0.01 ?m but smaller than 0.5 ?m, and a second large particle-diameter silica whose particle diameter is not smaller than 0.5 ?m but not larger than 20 ?m. The first small particle-diameter silica is localized to exist in large quantity on a side of the first principal surface, and the second large particle-diameter silica is localized to exist in large quantity on a side of the second principal surface.Type: GrantFiled: March 31, 2011Date of Patent: September 1, 2015Assignee: SEIKU CHEMICAL CO., LTD.Inventors: Reona Yokota, Koichi Shibayama, Akihiro Uenishi, Hidenobu Deguchi, Tomoki Kunikawa, Tatsushi Hayashi

Publication number: 20130288041Abstract: Provided is an epoxy resin composition capable of reducing the surface roughness of the surface of a roughening-treated cured body. The epoxy resin composition includes an epoxy resin, a curing agent, and a silica component obtained by performing a surface treatment on silica particles using a silane coupling agent; and the epoxy resin composition does not include a curing accelerator, or includes a curing accelerator at a content equal to or less than 3.5 parts by weight to a total of 100 parts by weight of the epoxy resin and the curing agent. Mean particle diameter of the silica particles is equal to or less than 1 ?m. An amount B (g) of the silane coupling agent used for surface treatment, per 1 g of the silica particles in the silica component, is within a range between 10% to 80% with regard to a value C (g) per 1 g of the silica particles, which is calculated by the following formula (X).Type: ApplicationFiled: June 20, 2013Publication date: October 31, 2013Inventors: Nobuhiro GOTO, Masaru HEISHI, Hidenobu DEGUCHI, Takayuki KOBAYASHI, Junnosuke MURAKAMI
