    摘要: A method of producing a laminate comprising a polypropylene adhesive layer (I) and a substrate layer (II), the method comprising a heat treatment step of performing a heat treatment under a temperature condition of 80 to 140°C for 5 to 120 minutes, wherein the laminate satisfies at least the following requirements (1) to (5):
    (1) the adhesive layer (I) includes 97 to 70% by weight of a propylene copolymer (A) and 3 to 30% by weight of a copolymer (B) having a structural unit derived from butene (where the total of copolymers (A) and (B) is 100% by weight),
    (2) the copolymer (A) has a melting point (TmA) of 70 to 120°C measured with a differential scanning calorimeter (DSC), and includes less than 1 mol % of a structural unit derived from butene,
    (3) the copolymer (B) has a melting point (TmB) of 130°C or less measured with a differential scanning calorimeter (DSC), and includes 1 mol % or more of the structural unit derived from butene,
    (4) the adhesive layer (I) includes a polymer (C)having a structural unit derived from at least one graft monomer selected from the group consisting of unsaturated carboxylic acids and derivatives thereof, and
    (5) the substrate layer (II) includes a polyester resin.

    摘要: Provided are an adhesive composition which has high adhesive strength and holding strength and leaves no residual glue by using a polyolefinic polymer, and an adhesive tape using the same. The adhesive composition contains (1) 5 to 95% by mass of a polyolefin having a melting point which is lower than 20°C or is not observed by a differential scanning calorimeter (DSC) and having a ”H of less than 5 J/g, and (2) 5 to 95% by mass of a polyolefin having a melting point of 20°C or higher and 160°C or lower and having a ”H of 5 J/g or more and 100 J/g or less, wherein the storage elastic modulus of the composition at 25°C obtained from the solid viscoelasticity measurement of the composition is 1 MPa or more and 200 MPa or less, and the storage elastic modulus thereof at 50°C is 1 MPa or more and 100 MPa or less.
