Abstract
A peelable bonded structure having a peel strength of 0.05 to 5 kg/cm comprises a plurality of articles, at least one of which is made of metal, bonded together through a composite coating layer. The composite coating layer is composed of adjacent first and second coating layers at least one of which comprises (A) a modified olefin resin having a carbonyl group concentration of 0.01 to 200 milliequivalents per 100 g of the olefin resin and (B) a coating film-forming base resin at an (A)/(B) weight ratio of from 0.2/99.8 to 40/60 and has a multi-layer distribution structure having resin concentration gradients in the thickness direction such that the modified olefin resin (A) is distributed predominantly in the portion contiguous to the interface between the two coating layers and the base resin (B) is distributed predominantly in the opposite portion.
