摘要： PROBLEM TO BE SOLVED: To provide an original plate for a heat sensitive lithographic printing plate capable of printing by mounting in a printer as it is without treating after scanning exposure based on a digital signal, having excellent plate wear resistance and difficulty to stain and improving a sensitivity. SOLUTION: The original plate for the heat sensitive lithographic printing plate comprises (1) an ink acceptive layer and (2) a hydrophilic layer containing a colloidal particle-like oxide or a hydroxide of at least one element selected from the group consisting of beryllium, magnesium, aluminum, silicon, titanium, boron, germanium, tin, zirconium, iron, vanadium, antimony and transition metals on a support. In this case, at least one layer of the acceptive layer and the hydrophilic layer contains a photothermal conversion agent. The acceptive layer contains an epoxy resin having a softening temperature according to a ring and ball method of 120 deg.C or higher of 95 to 30 pts.wt. and a polyalkylmethacrylate resin having a softening temperature according to the ring and ball method of 120 deg.C or lower of 5 to 70 pts.wt.

摘要： PROBLEM TO BE SOLVED: To provide an original plate for a heat sensitive lithographic printing plate capable of printing by mounting in a printer as it is without treating after scanning exposure based on a digital signal, having a high sensitivity and a high plate wear resistance and not bringing about an adhesion of a fingerprint mark even by handling with bare hands. SOLUTION: The original plate for the heat sensitive lithographic printing plate comprises (1) a heat sensitive layer containing a microcapsule for including a lipophilic component to be converted into an image part by a heat and a hydrophilic polymer, and (2) a hydrophilic overcoating layer sequentially in this order on a support. At least one layer of the heat sensitive layer and the overcoating layer contains a photothermal conversion agent. The overcoating layer contains a water swelling resin obtained by partly crosslinking a water soluble resin.

摘要： PROBLEM TO BE SOLVED: To provide an original plate for heat sensitive lithographic printing, which is capable of printing directly through a printer without processing after exposure and provided with the substrate of an aluminum film improved in a sensitivity. SOLUTION: The original plate for heat sensitive lithographic printing is provided on the aluminum substrate with an ink receptor layer as well as a hydrophilic layer containing a colloidal granular oxide or the hydrogenate of at least one element selected from beryllium, magnesium, aluminum, silicon, titanium boron, germanium, tin, zirconium, iron, vanadium, antimony and transition metal while at least one layer of the ink receptor layer and the hydrophilic layer contains a light/heat converting agent. In this case, the aluminum substrate is characterized by having an anodized film of 2 g/m2 or more and receiving the application of bore widening treatment as well as the sealing treatment of more than 50% of sealing rate.
