Heat-transfer label assembly and method of using the same

摘要

A heat-transfer label assembly and method of using the same. In one embodiment, the assembly is well-suited for decorating refillable glass articles and includes a support portion, a wax skim coat, and a transfer portion. The support portion may include a carrier web overcoated with a polyethylene layer. The wax skim coat may overcoat the polyethylene layer. The transfer portion may include a protective lacquer, an ink design, and a heat-activatable adhesive. The protective lacquer may be printed directly on the skim coat and may include a cross-linked phenoxy resin. The ink design may be printed onto the protective lacquer and may include a binder, a colorant, and a cross-linking system. The adhesive, which may differ from the ink design only by lacking colorant, may be printed onto the ink design, any exposed portions of the protective lacquer, and the surrounding skim coat.

主权项

1. A heat-transfer label assembly, said heat-transfer label assembly comprising:
(a) a support portion; and (b) a transfer portion over said support portion for transfer of the transfer portion to an article upon application of heat to the support portion while the transfer portion is placed in contact with the article, said transfer portion comprising
(i) a protective lacquer, said protective lacquer being over said support portion and comprising a cross-linked phenoxy resin;(ii) an ink design, said ink design being over at least a portion of said protective lacquer, said ink design comprising a binder, a colorant and a cross-linking system, said binder comprising at least one copolyester resin and a vinyl chloride/vinyl acetate resin, said cross-linking system comprising (A) a cross-linking resin for cross-linking said binder, said cross-linking resin comprising a melamine-formaldehyde resin and (B) a heat-activatable catalyst, said heat-activatable catalyst comprising an amine-blocked sulfonic acid catalyst; and(iii) a heat-activatable adhesive, said heat-activatable adhesive being over said ink design, said heat-activatable adhesive comprising a cross-linked resin.
