Abstract

The present invention relates to heat transfers that include silicone based heat transfer inks and digitally printed toner images, particularly for use on fabrics, apparel items, garments and accessories. The present subject matter is especially suitable for use in heat-transferable labeling or creating embellishments on polyester fabrics and garments.

First claim

The invention claimed is:

1. A heat transfer label comprising:
a support portion having a label carrier and a release layer; and
a transfer portion, the transfer portion being positioned over said support portion release layer for transfer of the transfer portion from the support portion to a fabric substrate under conditions of heat and pressure, the transfer portion comprising:
a heat transfer silicone ink layer having a first surface and a second surface, the first surface being exposed to permit direct contact with a fabric substrate to be labeled; and
an image layer comprising a printed toner layer, the image layer in contact with the second surface of the heat transfer silicone ink layer;

wherein the heat transfer silicone ink layer comprises a compatibility additive for adhering the toner layer to the heat transfer silicone ink layer, wherein the compatibility additive comprises decamethyltetrasiloxane, tetraethyl orthosilicate, and Titanium (IV) butoxide.

2. The heat transfer label of claim 1 , wherein the heat transfer silicone ink layer further comprises:
silicone ink base composition;
a pigment; and
a heat-transfer adhesion promoter being one or more of the group comprising:
a hydrogen bonded silicon;
an organosilane; and
a metal chelate.

3. The heat transfer label of claim 1 , wherein the heat transfer silicone ink layer further comprises at least one heat transfer adhesive.

4. The heat transfer label of claim 1 , wherein the image layer further comprises a printed water based ink layer.
