ABSTRACT:
A novel and useful ink jet recording transparency is described herein which is capable of wetting and absorbing colored, water soluble inks to provide permanent, high density images which are smear resistant. The transparency article of the invention includes a transparent resinous support which has a defined coating thereon. The coating is clear and consists essentially of a carboxylated, high molecular weight polymer or copolymer, or salts thereof, and, optionally, a pigment which is a particulate material. In the preferred embodiment of the invention, wherein high density images may be formed on a coated transparency from multiple jets of different colored inks which absorb such inks rapidly, the coating includes a carboxylated acrylic polymer which has been reacted with an organic amine.
