Abstract
(EN) The present invention relates to a thermosensitive lithographic printing plate and specifically, to a positive-image thermosensitive lithographic printing plate suitable for computer direct platemaking. The positive-image thermosensitive lithographic printing plate comprises a hydrophilic layer. The hydrophilic layer is sequentially coated by a lower layer and a top layer and is sensitive to infrared rays. The lower layer of the hydrophilic layer consists of alkali-soluble copolymer resin, near-infrared absorption dye, a dissolution inhibitor, a development promoter, and background coloring dye; and the top layer consists of phenolic aldehyde film-forming resin, near-infrared absorption dye, a dissolution inhibitor, a development promoter, and background coloring dye. The positive-image thermosensitive lithographic printing plate comprising alkali-soluble resin has high sensitivity, good development latitude, chemically-resistant performance and resolving power.
(FR) La présente invention concerne une plaque d'impression lithographique thermosensible et plus particulièrement, une plaque d'impression lithographique thermosensible à image positive convenant pour la réalisation directe de clichés sur ordinateur. La plaque d'impression lithographique thermosensible à image positive comprend une couche hydrophile. La couche hydrophile est revêtue de façon successive d'une couche inférieure et d'une couche supérieure et est sensible aux rayons infrarouges. La couche inférieure de la couche hydrophile est constituée d'une résine de copolymère soluble dans les alcalis, d'un colorant absorbant dans le proche infrarouge, d'un inhibiteur de dissolution, d'un promoteur de développement, et d'un colorant de coloration d'arrière-plan ; et la couche supérieure est constituée de résine formant un film d'aldéhyde phénolique, d'un colorant absorbant dans le proche infrarouge, d'un inhibiteur de dissolution, d'un promoteur de développement, et d'un colorant de coloration d'arrière-plan. La plaque d'impression lithographique thermosensible à image positive comprenant une résine soluble dans les alcalis possède une sensibilité élevée, une bonne aptitude au développement, est très résistante chimiquement et présente un haut pouvoir de résolution.
(ZH) 一种热敏平版印刷版版材，具体涉及一种适用于计算机直接制版的阳图热敏平版印刷版。包括一个亲水层，所述亲水层上依次涂有下层和顶层，所述亲水层对红外射线敏感。亲水层的下层由碱溶性共聚树脂、近红外吸收染料、溶解抑制剂、显影促进剂和背景着色染料组成；顶层由酚醛成膜树脂、近红外吸收染料、溶解抑制剂、显影促进剂和背景着色染料组成。含有上述碱溶树脂的阳图热敏平版印刷版版材具有高感度、良好的显影宽容度、耐化学品性能及解像力。
