Method for the preparation and application of pressure and heat applied image transfers
DCFirst Claim
1. A method for preparing a pressure and heat applied image transfer sheet and applying an image therefrom to a target surface comprising:
- applying an image layer to an image area of an image release system on a support, the image release system comprising a release coating comprising a wax and a lacquer that extends under and beyond borders of the image layer;
then applying a pressure and heat activated adhesive layer over the image layer and the image release system beyond the border of the image layer after the image layer has been applied to the image release system, which adhesive layer adheres more strongly to the image layer than the image layer does to the release surface and the adhesive layer adheres more strongly to the release system than to the target surface;
contacting, with the application of pressure and heat, the target surface and the image transfer sheet such that the adhesive layer attaches only in the image area to the target surface;
and peeling off the support together with the portion of the adhesive layer beyond the borders of the image area, leaving the image layer attached to the target surface.
