Abstract
Abstract An improved ink jet recording transparency is described herein which is capable of absorbing colored, aqueous-miscible inks to provide very high density images which are permanent and smear resistant. This transparency article includes a transparent resinous support and an improved coating which is clear and comprises a mixture of a carboxylated polymer or copolymer, having a molecular weight of about 50,000 to 1 million, and a polyalkylene glycol having an average molecular weight of about 5,000 to 25,000, preferably 15,000 to 25,000, the glycol being present in an amount of about 5% to 70%, preferably 10% to 25%, by weight of said polymer.
