Abstract: A heat activatable printable material for the ink-jet printing process comprising a support and a heat-activatable polymer layer. The polymers of the polymer layer is a mixture of nonionic water soluble polyethylene oxide polymers with the general formula H—[—O—CH2—CH2—]nOH, and an aliphatic polyester type polyurethane resin. The polymer layer is ink-jet printed and heat activated to adhere to a substrate with the support remaining on the polymer layer after adhesion of the polymer layer to the substrate.

Abstract: Ink jet printing materials comprise a support and an ink receiving layer containing a pigment, a hydrophilic binder comprising polyvinyl alcohol, vinylpyrrolidone homopolymer and/or vinylpyrrolidone copolymer, and a quaternary ammonium compound.

Abstract: This disclosure relates to production of a photographic film assembly substantially free of optical pinholes for use as a base for negatives in self-developing film packs. The assembly comprises a paper layer and first and second layers of polyolefin adhered to opposite sides of the paper layer. The paper layer has a caliper of about 2 mils to about 4.5 mils and a basis weight of about 55 g/m.sup.2 to about 125 g/m.sup.2. The first and second polyolefin layers each have a layer weight of about 10 g/m.sup.2 to about 48 g/m.sup.2. Carbon black is uniformly dispersed in at least two out of the three layers. The total amount of carbon black in the assembly is about 2.5 g/m.sup.2 to about 4.0 g/m.sup.2.

Abstract: A process is provided to produce a novel photographic base by applying an aqueous coating composition containing aluminum oxide particles to at least one surface of a substrate, drying the coated substrate, applying a molten film of a polyolefin over at least one of the coated surfaces of the coated substrate, adhering the polyolefin to the coated surface, and cooling the polyolefin film to a temperature below the melt point of the polyolefin. The photographic base so produced may be further treated by applying a coating of a light sensitive silver halide emulsion to one side of the photographic base paper and drying the emulsion coated paper.
