<p>In vessel closures in which a packing (9) is bonded to a shell (7) by means of coating layers (3,4,6,) and it is wished to peel the packing (9) away from the shell to reveal, for example, a prize mark (5), problems are frequently encountered in providing an easily peelable interface between the coating layers. In order to overcome these difficulties, in the present invention a peelable interface is provided between a first coating layer (3) comprising (i) a modified hydrocarbon resin or (ii) a composition containing such a modified resin, said resin (i) and said composition (ii) having an acid value of from 0.1 to 2.0, and a second coating layer (4) containing an epoxy resin.</p> |
