Abstract
Abstract A method for decorating substrate materials such as flat metal sheet or cylindrical metal containers in which a linear polyester/adhesive laminate film is applied to the substrate either prior to or simultaneously with a flexible dye transfer carrier. Thus, on heating the laminate film bonds to the substrate and dye is transferred from the carrier to the film. After cooling the carrier is removed, leaving a high gloss, finely decorated laminate film/substrate.

Claim 1
Independent Claim
211 words
A method of decorating a side wall of a container body comprising the steps of (a) providing a container body having a side wall including an exterior surface, (b) providing a base coating laminate including a layer of polyester film and a layer of heat-sensitive adhesive, (c) providing a flexible paper carrier printed with indicia in a sublimable dye, (d) first applying the base coating laminate to the container body side wall exterior surface with the adhesive thereof in contact with the container body exterior surface, (e) heating the heat-sensitive adhesive to activate the heat-sensitive adhesive and bond the polyester film of the base coating laminate to the container body, (f) following step (e) applying the flexible paper carrier with the sublimable dye against the layer of the polyester film in such a position as to effect the migration of the dye from the carrier directly to the layer of polyester film, (g) heating the paper carrier in order (1) to effect shrinkage of the paper carrier to tighten it into intimate contact with the polyester, and (2) to effect the migration of the sublimable dye and indicia from the paper carrier to the layer of polyester film, and then (h) removing the paper carrier from the layer of polyester film.
