Abstract

Transparencies for receiving images from aqueous inks, such as those commonly used in thermal ink jet printers, generally comprise a polymeric film base and a polymeric image receiving coating on at least one surface of the film base. The degree of transparency of the sheet can be undesirably impaired by haze in the polymeric image receiving coating. In some instances, it is believed that haze forms in this layer as a result of crystate formation or polymer crystallization in the polymeric image receiving coating material. It is proposed herein to suppress haze in the polymeric image receiving layer of transparencies by incorporating into the image receiving layer one or more hydrotropic materials.
