In ink jet printing, a liquid material is typically projected onto a substrate. The inks are usually aqueous .solutions and are most commonly projected onto paper substrates. There is a desire and a need to provide a capability of such ink jet printing devices to produce transparencies. However, most of the aqueous inks when projected onto the transparent substrate, coalesce into drops. It is proposed to coat the transparent plastic film with a latex emulsion such as vinyl acetate copolymer or homopolymer through which the aqueous inks when projected onto the transparent substrate will dry without coalescing into drops. Typically, the transparent substrate may be made from a transparent plastic film such as polystyrene, cellulose acetate or polyester and the ink once projected onto the transparency may be allowed to dry before using the transparency. Desired forced air may be used to hasten the drying. Typical vinyl acetate, copolymers or homopolymers are the resin series Resyn 1103, 1104, 1105, 1025 and 1251 available from National Starch.
