Abstract

A method for labeling fabrics, such as fabric garments, and a heat-transfer label (311) well-suited for use in said method. In one embodiment, the heat-transfer label (311) comprises (i) a support portion (313), the support portion (313) comprising a carrier (315) and a release layer (317); (ii) a wax layer (319), the wax layer overcoating the release layer (317); and (iii) a transfer portion (321), the transfer portion (321) comprising an adhesive layer (323) printed directly onto the wax layer (319) and an ink design layer (325) printed directly onto the adhesive layer (323). Each of the adhesive layer (323) and the ink design layer includes a non-cross-linked PVC resin. The ink design layer may be screen printed onto the adhesive layer (323) or may be printed onto the adhesive layer (323) using thermal transfer printing, ink jet printing or laser printing.

Dependent claims

A heat-transfer label suitable for labeling fabric comprising:

(a) a support portion;
and
(b) a transfer portion, said transfer portion being positioned over said support portion for transfer of the transfer portion from the support portion to an article of fabric under conditions of heat and pressure, said transfer portion comprising
(i) an ink design layer, said ink design layer comprising a thermochromic ink design;
and
(ii) a heat-activatable adhesive layer, said heat-activatable adhesive layer having a thickness of about 10 to 200 microns and having a surface roughness not exceeding about 10 microns;
(iii) wherein said ink design layer is printed directly onto said heat-activatable adhesive layer, said heat-activatable adhesive layer being positioned between said ink design layer and said support portion, said ink design layer having a top surface opposite said heat-activatable adhesive layer, said top surface being exposed to permit its direct contact with a fabric to be labeled.
