PROBLEM TO BE SOLVED: To provide an original plate for a lithographic printing plate which is mounted on a printing machine as it is without development after an image is written and which has high sensitivity, good plate wear and gives a printed matter generating no remaining of color and stain and which can be directly made into a printing plate from digital data by recording by using a solid laser or a semiconductor laser, etc., emitting IR rays. SOLUTION: The original plate for the lithographic printing plate is characterized by having a heat-sensitive layer containing a resin with a hydrogen-donating group and a resin with a hydrogen-accepting group on a substrate whose surface is hydrophilic and by at least one of the resin with the hydrogen-donating group and the resin with the hydrogen-accepting group being a fine particle. |
