ADHESIVE COMPOSITION, ADHESIVE FILM AND METHOD FOR TREATING SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide an adhesive composition which has flexibility and is excellent in adhesion to a substrate interface, an adhesive film, and a method for treating a substrate, using the adhesive composition.SOLUTION: An adhesive composition includes: a hydrocarbon resin; an elastomer in which the ratio of a monomer unit having a double bond in its main chain to all monomer units is 1 mol% or less; and a solvent. Relative to 100 pts.wt. of the hydrocarbon resin, the elastomer is included in the range of ≥1 pt.wt. and <20 pts.wt.
