Abstract
There is provided a process for heat transfer printing, comprising electrostatically printing a transparent electrostatic ink composition (3) onto a transfer material (2), wherein the transparent electrostatic ink composition comprises a thermoplastic resin; printing an image (4) on the transparent electrostatic ink composition; contacting the image with a target substrate (1) under conditions such that the thermoplastic resin of the transparent electrostatic ink composition is softened or molten, and separating the target substrate and the transfer material, to leave the target substrate having thereon the image and an overlying layer of transparent electrostatic ink composition. Also disclosed is a fabric having thereon an image, the image having an overlying layer of transparent electrostatic ink composition.
