The present invention relates to an adhesive sheet laminate which comprises a substrate layer composed of a thermoplastic resin composition (A) containing a polypropylene-based resin as a main component, an adhesive layer composed of a thermoplastic resin composition (B) containing a specific thermoplastic resin (b) as a main component and having a melt flow rate of 0.1 to 30 g/10 min, and a release layer composed of a thermoplastic resin composition (C) containing a specific thermoplastic resin (c) as a main component and having a melt flow rate of 0.1 to 30 g/10 min, and which has a tensile elastic modulus of 2000 MPa or more.

Described is a release composition comprising a polymer backbone with at least one C18-C22 alkyl (meth)acrylate monomer units, at least one C1-C6 alkyl (meth)acrylate methacrylate monomer units, and at least one styrenic monomer unit, and method of manufacture of the composition. Tape products incorporating the release composition as a release layer are also described.
