Abstract: A color filter array is disclosed containing interlaid sets of laterally displaced filters comprised of a polymeric matrix and at least one dye. At least one of the sets of filters is comprised of an anionic dye and a cationic polymeric mordant having crosslinking repeating units containing two quaternary ammonium mordanting moieties and a photogenerated ethylenic crosslinking moiety.

Abstract: A color filter array suitable for use in an image sensor is formed with a first layer having a mordant of one polarity and a first dye of the opposite polarity, and a second layer having a second mordant of a polarity opposite to the first mordant and a second dye of a polarity opposite to the second mordant.

Abstract: A photographically negative-working patternable mordant composition is disclosed containing a photocrosslinkable polymer comprised of, for providing both mordanting and crosslinking sites, repeating units of the formula: ##STR1## wherein Ar is an aromatic linking group,R is a methylene group,R.sup.1 is independently in each occurrence a lower alkyl group,R.sup.2 is a divalent linking group,X is a photocrosslinking group, andZ is a charge balancing counter ion.The mordant composition can be coated on a support to form a photographic element.

Abstract: A positive, continuous tone, dye image is produced by means of a dye imbibition imaging element comprising (a) a support having thereon, (b) a cationic mordant layer for an anionic dye, and (c) a sensitized photohardenable photopolymer layer consisting essentially of a photosensitive polyesterionomer. A process for forming a positive, continuous tone dye image in a dye imbibition imaging element, as described, comprises the steps of: (1) imagewise exposing the photopolymer layer of the element to activating radiation to imagewise harden the photopolymer layer; then (2) developing the photopolymer layer by means of water rinsing; and, then (3) imbibing an anionic dye into the mordant layer through the unexposed areas of the photopolymer layer. Alternatively, the process comprises immersing the imagewise-exposed element from step (1) into a bath comprising the anionic dye without the need for a water rinsing step.

Abstract: There is disclosed a composition and element, comprising a diazo resin and a mordant for anionic dyes that is compatible with the resin. The element of the invention is suitable for dye immersion and dye transfer to a mordanted receiver.

Abstract: A photothermographic element and composition for providing a dye image comprises (a) photographic silver halide in association with (b) an oxidation-reduction image-forming combination comprising (i) a silver salt oxidizing agent, with (ii) an organic reducing agent, (c) a polymeric binder for the element or composition and (d) a leuco-base dye which is oxidizable to form a dye image. After imagewise exposure of a photothermographic element or composition containing the described combination, a color image can be developed by overall heating the photothermographic element. Negative or positive dye images can be provided. The dye image can be transferred to an image receiver.
