A pigmented adhesive, halo-free heat transfer label is created when adhesive properties are incorporated into colored inks used to print graphics on labels for items such as apparel. The resulting label has a halo-free graphic applied thereto that eliminates the need for a separate application of adhesive to the label. A pigmented adhesive composition for use with heat transfer type labels includes a hydroxyl-functional polyurethane dispersion, one or more polyurethane dispersions different from the hydroxyl-functional polyurethane dispersion, a blocked cross-linking agent, a catalyst for the blocked cross-linking agent, a pigment dispersion, and an adhesive powder, which are combined prior to the formation of a graphic created using the combined mixture, on the release layer of a substrate.
A pigmented adhesive composition for use with a heat transfer label of the type wherein a graphic is formed on a substrate having a release layer thereon and the graphic is transferred from the release layer of the substrate onto an associated item using heat, the pigmented adhesive composition comprising:
A halo-free heat transfer label comprising:
