PROBLEM TO BE SOLVED: To provide an original film for lithography of a heat mode type which has high sensitivity and a wide exposure latitude without necessitating development, and can be made into a plate simply and also with direct fitting on a printing machine and, besides, which is excellent in plate wear and causes little printing stain on a printing surface. SOLUTION: In this original film for lithography, a hydrophobic layer or a metal thin-film layer containing a photothermal conversion agent is provided as a first layer on a support. Further, a hydrophilic layer containing metal particulates having photothermal conversion properties which scatter and remove layer-forming substances or embrittle them removably as light is converted into heat is provided as a second layer. |
