Abstract
A versatile method of cold transferring images without using supplemental heat in the course of image transfer to a wide variety of substrates includes printing an image with water-based ink onto an image transfer sheet that has a coating of water-accepting adhesive. The sheet is then applied to the substrate to transfer only the portions of the adhesive that bear the image onto the substrate, with the remainder of the adhesive remaining attached to the sheet. A method of manufacturing image transfer sheets includes first applying a water impermeable layer onto a flexible substrate. A layer of water-activatable adhesive is applied upon the water impermeable layer. The adhesive is then dried in a dryer with dehumidified air. A water permeable detack layer is then applied upon the layer of adhesive. A sheet for transferring an image that has been printed onto the sheet with a water-based ink has a flexible backing layer and one or more water-accepting layers with water activatable adhesive that are printed with a printing press and/or coated onto the flexible backing layer. A water-impermeable layer is disposed in between the adhesive and the backing layer. A detack layer may be appl…
