PRODUCTS, COMPOSITIONS, AND METHODS EMPLOYED IN SOLVENT-BASED INK JET PRINTING

摘要

A porous substrate for organic solvent-based ink printing may be coated with a repellant composition to form a coated substrate surface that is suitable for high quality solvent-based ink jet printing. The coated substrate surface may exhibit a repellancy for butoxyethyl acetate solvent at a contact angle of between about 40 and about 90 degrees at ambient temperature. In some applications, the repellant composition includes a fluorocarbon polymer, or a urethane. Solvent-based ink applied to the porous substrate will form droplets which under the application of heat deposit ink in a controlled and advantageous manner upon the treated substrate surface. An optional acrylate-based latex material may be employed in the repellant composition. A printed substrate is produced which exhibits clear, sharp and high quality print.
