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. The anionic dye is optionally transferable into another mordant layer.

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.
