Lithographic printing plate for infrared laser

A lithographic printing plate for infrared laser, which has a heat-sensitive layer containing the following (A) to (D):

• (A) a substance which absorbs a light to generate heat;
• (B) an alkaline aqueous solution-soluble resin having a phenolic hydroxyl group;
• (C) a polymer containing as a polymerizable component a (meth)acrylate monomer having 2 or 3 perfluoroalkyl groups containing 3 to 20 carbon atoms within the molecule;
• and
• (D) a fluorine-containing polymer containing as copolymerizable components at least the following 1) to 3):
• 1) an addition polymerizable, fluorine-containing monomer having in the side chain a fluoro aliphatic group wherein hydrogen atoms on the carbon atoms are replaced by fluorine atoms;
• 2) a monomer of the following structure [1] to [4];
• and
• 3) a monomer having an acidic hydrogen atom and having an acidic group wherein the acidic hydrogen atom is bound to a nitrogen atom:
• CH2═CA1[CO—W—R2] [1]CH2═CA1[O—CO—R3] [2]CH2═CA1[U] [3]
• 22
• wherein A1 represents a hydrogen atom, a halogen atom or an alkyl group, W represents oxygen or —NR1—, R1 represents a hydrogen atom, an alkyl group or an aryl group, R2 represents an optionally substituted alkyl group or an optionally substituted aryl group, R3 represents an alkyl group or an aryl group, and U represents a cyano group, an aryl group, an alkoxy group, an aryloxy group, an acyloxymethyl group, a nitrogen-containing hetero ring or —CH2OCOR3 (R3 being the same as defined above).
