An adhesive composition comprising
100 parts by weight of a block copolymer (a) containing of at least one polymer block composed mainly of a vinyl aromatic hydrocarbon and at least one polymer block composed mainly of butadiene in which
(i) the vinyl aromatic hydrocarbon content [S] is 10 to 30% by weight,
(ii) the 1,2-vinyl content of butadiene portion [V] is 20 to 50%, and
(iii) the relationship between said vinyl aromatic hydrocarbon content [S] and said 1,2-vinyl content of butadiene portion [V] satisfies the formula:
40 to 200 parts by weight of a tackifier (b), and, optionally contain
various stabilizers; and a process for producing said composition.
