PROBLEM TO BE SOLVED: To provide a heat-mode type lithographic printing original film, which necessitates, no development treatment, from which a die can be easily made, the die making from which is possible under the state directly being installed on a printing machine, which is excellent in recognizabilty between an image part and a non-image part and the printing scumming on a printing surface of which excellent in plate wear and inking properties is small. SOLUTION: In this lithographic printing original film, at least 2 kinds of fine particle polymers, the particle sizes of which are different from each other, are included in a hydrophilic resin polymer formed on a support by three- dimensional cross-linking. |
