International Classification:

US Classification:

430199

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. This alternative process enables the anionic dye to be imbibed into the mordant layer through the unexposed areas of the photopolymer layer without the need for removing a portion of the unexposed areas of the photopolymer layer.

Filed:

Oct 9, 1981

Appl. No.:

6/310168

Inventors:

Susan E. Hartman - Rochester NY

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

G03C 184

US Classification:

430293

Abstract:

A color filter array for a solid-state imaging device is disclosed. The color filter array is of the "wash-off" type wherein the individual filter elements are formed by dyeing tiny islands of a dyeable composition. As a barrier layer, the color filter array of the present disclosure uses a photocrosslinkable dye-impermeable polymer. The barrier is coated over a set of filter elements. A method of making the described solid-state device is also disclosed.

International Classification:

C07C14320

US Classification:

560118

Abstract:

A novel compound having the formula: ##STR1## wherein: R is alkyl containing from 1 to 10 carbon atoms; and M is a monovalent cation, selected from the group consisting of alkali metal and ammonium, has been synthesized in high yield by hydrogenating the corresponding arylsulfonate in a solvent which simultaneously prevents hydration of the sulfonate group and hydrolysis of the ester functions. The compound is useful in preparing condensation polymers having ionic groups. In particular, these condensation polymers comprise additional polymerized copolymerizable dicarboxylic acids and diols, diamines or hydroxyamines, to yield polyesterionomers useful in dye imbibition photohardenable imaging materials for forming positive dye images.
