To obtain a heat conductive pressure-sensitive adhesive composition having excellent balance between hardness and pressure-sensitive adhesiveness and further excellent shape following properties and flame retardance, and to prepare a heat conductive pressure-sensitive adhesive sheet.
The heat conductive pressure-sensitive adhesive composition is composed of 100 pts.wt. of an acrylic or a methacrylic ester copolymer (A) obtained by polymerizing 5 to 70 pts.wt. of a monomer mixture (A2m) composed of a specific amount of an acrylic or a methacrylic ester monomer having a specified structure, a specific amount of a monomer having an organic acid group and a specified amount of a monomer copolymerizable with the monomers in the presence of 100 pts.wt. of a copolymer (A1) containing a specific amount of a unit derived from an acrylic or a methacrylic ester monomer having a specified structure, a specific amount of a monomer unit having the organic acid group, a specified amount of a monomer unit containing a functional group other than the organic acid group and a specific amount of a monomer unit derived from a monomer copolymerizable with the monomers and 70 to 170 pts.wt. of a metal hydroxide (B). The acrylic or methacrylic ester copolymer (A) is foamed.
