<P>PROBLEM TO BE SOLVED: To provide a laminate constituted so that a vulcanized rubber and stainless steel are strongly bonded, reduced in the environmental dependence of the vulcanized rubber, soft and low in compression set, suitable for a semiconductive rubber roller for an electrophotographic process and achieved in cost reduction because no adhesive is used at the time of adhesion. <P>SOLUTION: The laminate is constituted by bonding a composition for a semiconductive vulcanized rubber, which contains 100 pts.wt. of an epichlorohydrin rubber (A), 0.1-10 pts.wt. of a 2, 3-dimercaptoquinoxaline derivative (B) represented by general formula (I) (wherein R<SP>1</SP>, R<SP>2</SP>, R<SP>3</SP>and R<SP>4</SP>are each a hydrogen atom or a 1-4C alkyl group), 0.1-20 pts.wt. of hydrotalcite (C) and 0.1-20 pts.wt. of magnesium oxide (D), and stainless steel under a vulcanizing condition. <P>COPYRIGHT: (C)2007,JPO&INPIT |
