    摘要: A light-sensitive composition for the preparation of printing plates is described, which contains a water-insoluble binder which is soluble in aqueous-alkaline solutions; a light-sensitive component which is an o- or p- quinone diazide, a diazonium salt polycondensation product or a mixture of(a) a compound which eliminates an acid on exposure to light and(b) a compound having at least one C--O--C group which can be split by acid; and a thermo-crosslinking compound which is a cyclical acid amide of the general formula: ##STR1## wherein R denotes a hydrogen atom or an alkyl group. The printing plates can be baked at lower temperatures than plates without a crosslinking agent, but nevertheless have a long shelf life.

    摘要: A negative-acting color proofing element comprising, sequentially, (i) a strippable, transparent cover sheet; (ii) a crosslinked layer, which comprises a polymer having phenolic groups; (iii) a color layer, which comprises an organic binder, a polymerizable monomer, a colorant, and an optional photoinitiator, (iv) a photoadhering layer, which comprises a polymerizable component having at least one ethylenically unsaturated group; a polymer comprising polyvinyl acetal and polyvinyl alcohol segments, having from about 1 to about 40 weight % polyvinyl alcohol content; and an optional photoinitiator, wherein least one of either the color layer or the photoadhering layer contains a photoinitiator; (v) a thermoplastic adhesive layer; and (vii) a receiver sheet. Preferably the polymerizable component and photoinitiator diffuse into the color layer during assembly of the element. An image is produced by laminating the photosensitive element to a receiver sheet; imagewise exposing the color layer and the photoadhering layer to actinic radiation through the transparent cover and crosslinked phenolic layer; peeling apart the receiver sheet and the transparent cover sheet, leaving exposed areas of the color layer attached to the receiver sheet via the photoadhering layer and adhesive layer and unexposed areas being removed with the cover sheet and the crosslinked phenolic layer, thereby forming a colored negative image on the receiver sheet. Preferably these image producing steps are repeated at least once wherein another photosensitive element having a different colorant is transferred via its photoadhering and adhesive layers to the negative image previously produced on the receiver sheet.
