Provided is a cmposition having an excellent adhesiveness to adherent, such as plastic (especially polypropylene). This composition comprises the following (A) and (B), (A): a polymer (A-1) containing the structure units originally from propylene and 1-butene, the content of the structure unit originally from propylene is 70 to 99 mole%, the content of the structure unit originally from 1-butene is 1 to 30 mole%, and substantially no fusion peak being observed, or a polymer (A-2) obtained by modifying the polymer (A-1) with α , β -unsaturated carboxylic acids; (B) a polymer (B-1) containing the structure units originally from ethylene and propylene, the content of the structure unit originally from ethylene is 5 to 20 mole%, the content of the structure unit originally from propylene is 80 to 95 mole%, and a fusion peak being observed, or a polymer (B-2) obtained by modifying the polymer (B-1) with α , β -unsaturated carboxylic acids. |
