Abstract

A tonable, aqueous-processable, photosensitive element and process for forming a colored image from said element is described. The element comprises a support and a tonable, aqueous-processable photosensitive layer, said photosensitive layer consisting essentially of (a) an aqueous-processable, photoinsolubilizable photosensitive composition comprising a photosensitive material, and (b) a water-soluble plasticizer, wherein said photosensitive material is present in sufficient amount to insolubilize said photosensitive layer on exposure to actinic radiation, said photosensitive composition is present in sufficient amount to form a layer when said photosensitive layer is coated, and said plasticizer is present in sufficient amount to make said photosensitive layer.

Dependent claims

A tonable, aqueous-processable photosensitive element comprising:

(A) a support, and
(B) a solid, tonable, aqueous-processable photosensitive layer consisting essentially of
(1) an aqueous-processable, photoinsolubilizable, photosensitive composition comprising a photosensitive material, and
(2) a water-soluble plasticizer, wherein said photosensitive material is present in sufficient amount to insolubilize said photosensitive layer on exposure to actinic radiation, said photosensitive composition is present in sufficient amount to form a solid layer when said photosensitive layer is coated, and said plasticizer is present in sufficient amount to make said photosensitive layer tonable at room temperature before and after exposure to actinic radiation;
said photosensitive material and said plasticizer being present in admixture in said photosensitive layer.
