NOVELTY - An adhesive agent comprises a modified olefin polymer (A) in which a polymer of 2-20C alpha -olefin including structural units derived from 4-20C alpha -olefin is modified by a monomer having a functional group which is capable of reacting with an isocyanate group, and a polyisocyanate (B). The heat of fusion of the modified olefin polymer (A) is 0-50 J/g, as measured based on JIS K7122.    USE - Adhesive agent is used for forming adhesive bond layer in laminate, wrapping material for battery, and wrapping material for packaging alkaline solution and alcohol-containing solution (all claimed).    ADVANTAGE - The adhesive bond layer formed using the adhesive agent has excellent durability and adhesiveness.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) laminate, which has a base material, and an adhesive bond layer provided on one side of the base material. The adhesive bond layer is formed using a coating agent containing adhesive agent;    (2) battery case wrapping material (1), which has a base material (2), an inner side layer (3) adhered inside the base material, an outer side layer (4) adhered on the outer side of the base material, an inner side adhesive bond layer (5) provided between the base material and the inner side layer and containing a cured material of the adhesive agent, and an outer side adhesive bond layer (6) provided between the base material and the outer side layer;    (3) battery, which consists of the battery case wrapping material, and an electrolyte solution packaged by the battery case wrapping material. At least one portion of the inner side layer of the wrapping material is contacted with the electrolyte solution;    (4) high-alkaline solution wrapping material, which has a base material, an inner side layer adhered inside the base material, and an inner side adhesive bond layer provided between the base material and the inner side layer and containing cured material of the adhesive agent;    (5) package, which is obtained by packaging a solution having pH of 9 or more using the alkaline solution wrapping material;    (6) alcohol-containing solution wrapping material; and    (7) package, which is obtained by packaging a alcohol-containing solution using the alcohol-containing solution wrapping material.    DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of batter case wrapping material. (Drawing includes non-English language text)    Battery case wrapping material (1)    Base material (2)    Inner side layer (3)    Outer side layer (4)    Inner side adhesive bond layer (5)    Outer side adhesive bond layer (6)
