| 摘要 |
<p>The present invention concerns a lithographic printing plate precursor comprising i) an aluminum substrate being subjected to a an electrochemical surface-roughening treatment in an aqueous solution comprising hydrochloric acid, ii) an image-recording layer selected from an image-recording layer comprising at least two types of fine particles selected from (a) heat-fusible fine polymer particles, (b) fine polymer particles having a heat-reactive functional group, and (c) microcapsules containing therein a heat-reactive compound, at least one of which undergoes combination by heat to form an image, an image-recording layer comprising self water-dispersible fine resin particles undergoing combination by heat and is writable by infrared laser exposure, and an image-recording layer, which is a lipophilic image-recording layer being free from a hydrophilic binder resin and comprising hydrophobic fine polymer particles undergoing combination by heat, a light-to-heat converting agent and a water-insoluble compound having fluidity at 50 DEG C; and which further comprises an overcoat layer comprising a water-soluble resin, and iii) a hydrophilic film having a heat conductivity of 0.05-0.5 W/mK.</p> |
