Abstract
To provide a resin composition excellent in conformability to special shapes and in holding power without the need of containing a low molecular softener such as a plasticizer, other than a polysiloxane, and a cured product and a sheet using it. A resin composition characterized by comprising (a) an acrylic rubber, (b) a compound containing at least two mercapto groups per molecule, (c) a compound containing at least two acryloyl and/or methacryloyl groups per molecule, (d) an acrylate and/or methacrylate having a C2-12 alkyl group, and (e) acrylic acid or methacrylic acid. The above resin composition which contains a thermally conductive filler. A cured product and sheet using it.
