PROBLEM TO BE SOLVED: To provide an IR sensitive composition which imparts a good coated surface state and excellent printing and scuffing resistances to the image forming layer of a planographic printing original plate when used as the material of the image forming layer. SOLUTION: The IR sensitive composition comprises (A) a resin insoluble in water and soluble in alkaline water, (B) a photothermal conversion material, (C) a fluoropolymer obtained by polymerizing a monomer containing one specified fluoroaliphatic group and (D) a fluoropolymer obtained by polymerizing a monomer containing two or more specified fluoroaliphatic groups. |
