PROBLEM TO BE SOLVED: To provide a heat mode-type original plate for lithographic printing with such advantages that on original plate can be easily made up without the necessity to perform a development process and also can be made up by directly mounting the original plate on a printing machine and is almost free from print scumming on a printed surface and shows excellent resistance to plate wear with the high coating film strength of an image recording layer. SOLUTION: This original plate for lithographic printing has an image recording layer composed substantially of a hydrophobic precursor particles, formed on a support, the hydrophobic precursor being a polymer fine particle having a hydrophilic graft chain on the surface, and enables an image to be formed preferably by light emission in the heat mode. |
