Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a planographic printing plate for blue semiconductor laser which has a high practical sensitivity to an output machine using a blue semiconductor laser, can be handled in a bright room, and has high printing durability and good storage stability as a printing plate. SOLUTION: The planographic printing plate which has at least a silver halide emulsion layer and a physical development nucleus layer on a support, is characterised in that the silver halide emulsion layer contains at least one of the sensitizing dyes represented by formula (I) wherein R1-R4represent H, an optionally substituted alkyl, alkoxy, allyl, aryl, halogen or a heterocyclic group, R1and R2can be bonded together to form a condensed ring; A represents an alkylene; and Q represents an alkyl having a multiple bond or a heterocyclic group.
