Abstract
This invention relates to a process for making an image-recording element, for example a dye-receiving element for thermal dye transfer, that includes a support having on one side thereof a image-receiving layer and, between the image-receiving layer and the support, a tie layer comprising a thermoplastic antistat polymer. In one embodiment, the process comprises (a) forming a first melt of a polymer for the surface layer and a second melt comprising a thermoplastic antistat polymer in a polymeric binder; (b) coextruding the two melts onto a polyolefin support; (c) stretching the coextruded layers to reduce the thickness; and (d) applying the coextruded melts to a support while simultaneously reducing the temperature below the Tg of the composition of the surface layer.
