CLAIMS

1. A heat transfer label comprising:

a support portion having a label carrier and a release layer; and

a transfer portion, said transfer portion being positioned over the 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;

an image layer comprising a printed toner layer; and

a compatibility layer in contact with the second surface of the heat transfer silicone ink layer, wherein the compatibility layer adheres the toner layer to the heat transfer silicone ink layer.

2. The heat transfer label of claim 1, wherein the heat transfer silicone ink layer 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 2, wherein the heat transfer silicone ink layer further comprises at least one heat transfer adhesive.

4. The heat transfer label of claim 2, wherein the compatibility layer is transparent.

5. The heat transfer label of claim 2, wherein the compatibility layer has a thickness of about 1 gsm.

6. The heat transfer label of claim 2, wherein the compatibility layer is formed from a composition comprising decamethyltetrasiloxane, tetraethyl orthosilicate and Titanium (IV) butoxide. Reactive silanes and colloidal silica.

7. The heat transfer label of claim 2, wherein the image layer further comprises a printed water based ink layer.

8. 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.

9. The heat transfer label of claim 8, wherein the heat transfer silicone ink layer 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; and

a compatibility additive comprising decamethyltetrasiloxane, tetraethyl

orthosilicate and Titanium (IV) butoxide.

10. The heat transfer label of claim 8, wherein the heat transfer silicone ink layer further comprises at least one heat transfer adhesive.

11. The heat transfer label of any one of claims 8, wherein the image layer further comprises a printed water based ink layer.

A heat transfer label, comprising;

a water based ink;

a toner image layer; and

wherein the toner image layer is substantially covered by the water based ink.
