An inkjet printing system comprises an inkjet printer and an inkjet ink comprising water, a self-dispersing carbon black pigment, and a water soluble polymer containing carboxylate groups, wherein:

Inkjet printing system, ink, and process

This invention is related to an inkjet ink comprising water, a first self-dispersing pigment, and a second self-dispersing pigment, wherein said first self-dispersing pigment comprises a charged group bonded directly to the surface thereof, and said second self-dispersing pigment comprises a charged group bonded through a linking group to the surface thereof.

Aqueous inkjet ink composition

This invention relates to packaged photographic film that is capable of being alternately processed, according to individual consumer choice, by either (1) a traditional wet-chemistry process with a developer solution followed by desilvering in one or more subsequent solutions to obtain a color negative film, or (2) a dry thermal process without the use of aqueous solutions in which a blocked developing agent located within the photographic element is thermally activated or unblocked, optionally followed by electronic scanning of the developed film without desilvering. This invention enables a single film stock to be developed in both a conventional deep tank process and in a dry thermal process.

Packaged color photographic film capable of alternatively dry or wet-chemical processing

A radiation-sensitive high bromide {111} tabular grain emulsion is disclosed in which at least 90 percent of silver halide epitaxy of an isomorphic face centered cubic crystal lattice structure containing at least 1 mole percent iodide is deposited on the {111} major faces in the form of monocrystalline terraces. Each epitaxial terrace is grown from a nucleation site along an edge of a {111} major face inwardly, with terraces overlying less than 25 percent of the {111} major faces. Surprisingly, these emulsions exhibit higher photographic speeds than those produced by growing silver halide epitaxy outwardly as protrusions from the corners or edges of the tabular grains.
