Abstract
An Ink transfer medium configured to receive and transfer an image on a bi-dimensional or tri-dimensional article by way of thermal transfer. The ink transfer medium includes a sub-layer made of amorphous polyethylene terephthalate (APET), an image receiving coating, a barrier coating, a binding system, and an ink transfer coating which includes a layer having a combination of pigment systems formed by cellulose fibers, microspheres and silica. The barrier coating includes resins and mineral elements supporting the ink transfer coating applied on the APET film.

An Ink transfer medium configured to receive and transfer an image on a bi-dimensional or tri-dimensional article by way of thermal transfer, said ink transfer medium comprising:
- a coating of amorphous polyethylene terephthalate (APET) film;
- an image receiving coating;
- a binding system;
- an ink transfer coating including a combination of pigment systems formed by silica and a mixture of ink carriers;
- and
- a barrier coating including resins and mineral elements configured to support the ink transfer coating applied on the APET film.
A process for obtaining an ink transfer medium configured to receive and transfer an image on a bi-dimensional or tri-dimensional article by way of thermal transfer, the process comprising:
- providing a coating of pre-treated amorphous polyethylene terephthalate (APET) film, an image receiving coating, a binding system, an ink transfer coating including a combination of pigment systems formed by silica and a mixture of ink carriers, and a barrier coating including resins and mineral elements configured to support the ink transfer coating applied on the APET film.
An Ink transfer medium comprising:
- a coating of amorphous polyethylene terephthalate (APET) film;
- an image receiving coating;
- a binding system;
- an ink transfer coating including a combination of pigment systems formed by silica and a mixture of ink carriers;
- and
- a barrier coating including organic resins and mineral elements configured to support the ink transfer coating applied on the APET film,
- wherein the organic resins are formed by at least one of casein and its derivates in an aqueous solution with one of a mineral and an organic pigment system,
- wherein the ink transfer carriers comprise cellulose fibers and microspheres of methacrylate,
- wherein the binding system comprises resins chosen among polyvinyl alcohols, cellulose-based resins with one of plasticizers and softening agents incorporated into one of an aqueous alcohol and a hydro-alcohol.
