Sublimination dye thermal transfer paper and transfer method
First Claim
1. A method of applying a sublimation dye image to a receptor element, which comprises the steps of:
- (i) imaging a transfer sheet with sublimation dyes, wherein said transfer sheet comprises, in the following order;
(a) a support,(b) a barrier layer capable of releasing a polyester layer in the absence of water, chemicals or heat,(c) a polyester layer capable of being released from said barrier layer in the absence of water, chemicals or heat, said polyester being optionally imaged with sublimation dyes, and(d) an optional sublimation dye receiving layer which is present in the case where the polyester is not imaged with sublimation dyes, and;
(ii) peeling by physically separating in the absence of water, chemicals or heat the imaged polyester layer, or the polyester and the imaged optional sublimation dye receiving layer from the barrier layer,(iii) placing the peeled and imaged polyester layer or the polyester and the imaged optional sublimation dye receiving layer onto a receiving element,(iv) optionally placing a non-stick sheet onto the peeled imaged polyester layer or onto the polyester and the imaged optional sublimation dye receiving layer,(v) applying heat energy to the optional non-stick sheet or directly to the image bearing side of the receptor element to drive the polyester and sublimation dye image into said receptor element, wherein said sublimation dyes sublimate and penetrate into said polyester layer and adhere to said receptor element without an external adhesive layer;
and removing said optional non-stick sheet, when present, from said receptor element wherein the sublimation dye image-containing polyester layer is embedded in said receptor element.

Abstract
An image transfer sheet is provided which comprises a support, a barrier layer, a polyester layer and an optional a sublimation dye receiving layer; wherein the polyester is capable of being physically separated by the user without water, chemicals or heat. The peeled and imaged polyester is placed onto a receptor element and a non-stick sheet is optionally placed thereon. An iron is placed onto the optional non-stick sheet to drive the polyester and image into the receptor. The invention allows for both correct order image-wise printing and reverse order image-wise printing. This invention allows sublimation dye printing onto a cotton receptor.

18. A method of transferring an sublimation dye image to a receptor element comprising:
-
(i) imaging a transfer sheet with sublimation dyes, wherein the transfer sheet comprises, in the following order; (a) a support, (b) a barrier layer capable of releasing a polyester layer in the absence of water, chemicals or heat, (c) a polyester layer, and (d) an optional sublimation dye imaging receiving layer, and; (ii) positioning the imaged polyester layer or sublimation dye image receiving layer against said receptor element; (iii) applying heat energy to the rear surface of the transfer sheet to transfer said sublimation dye image and said polyester layer to said receptor element, wherein said sublimation dyes sublimate and penetrate into said receptor element together with the polyester; and (iv) stripping said transfer sheet away from said receptor element, wherein the sublimation dye image-containing polyester layer is adhered to said receptor element. - View Dependent Claims (19)

20. A method for transferring a pre-printed sublimation dye image to a receptor element by the steps comprising:
-
(i) providing a pre-printed transfer sheet, which comprises, in the following order; (a) a support, (b) a barrier layer capable of releasing a polyester layer in the absence of water, chemicals or heat, (c) a polyester layer capable of being released from said barrier layer in the absence of water, chemicals or heat, said polyester being optionally pre-printed with sublimation dye, and (d) an optional pre-printed dye sublimation layer, said optional imaged sublimation dye layer being present when said polyester layer does not contain an image, and; (ii) peeling by physically separating in the absence of water, chemicals or heat, the imaged polyester layer and optional sublimation dye containing layer from the barrier layer, (iii) placing the peeled and imaged polyester layer and sublimation dye containing layer onto a receiving element, (iv) optionally placing a non-stick sheet onto the peeled imaged polyester layer and sublimation dye containing layer, (v) applying heat energy to the optional non-stick sheet or directly to the image bearing side of the receptor element to drive the polyester and sublimation dye image into said receptor element, wherein said sublimation dyes sublimate and penetrate into said polyester layer and adhere to said receptor element; and (vi) removing said optional non-stick sheet, when present, from said receptor element, wherein the sublimation dye image-containing polyester layer is adhered to said receptor element. - View Dependent Claims (21)
