  • Publication number: 20140227471
    Abstract: Provided are a laminate body, a cross-linked product, and a molded member superior in interlayer adhesiveness. An acrylic elastomer layer 11 is prepared from an acrylic elastomer composition containing an epoxy group-containing acrylic elastomer as major component, an onium salt in an amount of 1 to 5 parts by mass and a polyol compound in an amount of 1 to 8 parts by mass with respect to 100 parts by mass of the acrylic elastomer, and a fluorine-based elastomer layer 12 is prepared from a fluorine-based elastomer composition containing a polyol crosslinking agent. The acrylic elastomer layer 11 and the fluorine-based elastomer layer 12 are laminated, to give a laminate body 1. The laminate body 1 is cross-linked, to give a cross-linked product or a molded member.
