A peelable adhesive structure comprising a plurality of parts, at least one of which is made of metal, adhering together by means of a coating, chracterized in that said coating has a peelable surface formed between a first layer of an acid-denatured hydrocarbon resin composition having an acid value of from 0.1 to 20 and a second layer containing an epoxy resin, said denatured hydrocarbon resin being obtained from the reaction between (A) a hydrocarbon resin precursor selected from the group consisting of (i) petroleum resins which are obtained by polymerization of cyclopentadiene or C.sub.9 to C.sub.11 olefin hydrocarbons, (ii) cumarone-indene resins and (iii) terpene resins, and (B) an ethylenically unsaturated carboxylic acid or its anhydride.
