Title (EN) LITHOGRAPHIC PRINTING PLATE PRECURSOR
(FR) PRÉCURSEUR DE PLAQUE D’IMPRESSION LITHOGRAPHIQUE
(JA) 平版印刷用原版
Abstract:
(EN) A lithographic printing plate precursor which is less apt to suffer contamination by ablation in image formation and gives, through image formation, a printing plate having excellent printing performance. The lithographic printing plate precursor comprises a substrate (I), a photosensitive layer (II) which has been formed on the substrate (I) and contains a light/heat conversion agent, and a layer (III) with which the photosensitive layer (II) is covered, wherein the layer (III) covering the photosensitive layer comprises a water-soluble polymer and a hydrophobic polymer and contains substantially no light/heat conversion agent. The layer (III) covering the photosensitive layer preferably comprises the water-soluble polymer and the hydrophobic polymer in a proportion of from 10/90 to 90/10 by mass.
(FR) La présente invention concerne un précurseur de plaque d'impression lithographique moins susceptible de subir une contamination par ablation lors de la formation d'image et fournissant, par formation d'image, une plaque d'impression offrant d'excellentes performances d'impression. Ledit précurseur comprend un substrat (I), une couche photosensible (II) formée sur le substrat (I) et contenant un agent de conversion de lumière en chaleur, et une couche (III) recouvrant la couche photosensible (II), ladite couche (III) comprenant un polymère hydrosoluble et un polymère hydrophobe et étant sensiblement dépourvue d'agent de conversion de lumière en chaleur. La couche (III) recouvrant la couche photosensible comprend le polymère hydrosoluble et le polymère hydrophobe de préférence dans un rapport allant de 10/90 à 90/10 en poids.
(JA)  本発明の目的は、画像の形成に際して、アブレーションによる汚染の恐れが少なく、しかも画像形成した印刷版が印刷性能に優れたものである平版印刷用原版を提供することである。支持体(I)、前記支持体(I)上の光熱変換剤を含有する感光層(II)、および前記感光層(II)を覆う層(III)を有する平版印刷用原版において、前記感光層を覆う層(III)が、水溶性ポリマーと疎水性ポリマーを含有し、かつ光熱変換剤を実質的に含有しない平版印刷用原版を提供する。感光層を覆う層(III)は、水溶性ポリマーと疎水性ポリマーを10:90~90:10の質量比で含有することが好ましい。
