Method for making lithographic printing plate

A method for making a lithographic printing plate comprising the steps of:

• light-exposing to infrared radiation, a heat-sensitive presensitized plate of a positive-working mode for use in making a lithographic printing plate, said presensitized plate comprising a substrate and an image recording layer which is formed thereon and comprises a novolak resin containing xylenol as a monomer component and an infrared absorbing dye;
• and
• developing the light-exposed plate with an alkaline developing solution comprising at least one surfactant selected from the group consisting of anionic surfactants represented by the following formulas (I), (II), (III) and (IV) and amphoteric surfactants represented by the following formulas (V) and (VI):
• wherein R1 and R2 independently represent hydrogen atom or an alkyl group which may be in the form of linear or branched claim, X and Y indepenendently represent a single bond or the formula —O—(CH2CH2O)n- wherein n is an integer of from 1 to 100, and M represents a monovalent alkali metal,
• wherein, R represents hydrogen atom or an alkyl group which may be in the form of linear or branched chain, X represents a single bond or the formula —O—(CH2CH2O)n- wherein n is an integer of from 1 to 100, and M represents a monovalent alkali metal,
• wherein X and Y independently represent a single bond or the formula —O—(CH2CH2O)n- wherein n is an integer of from 1 to 100, and M represents a monovalent alkali metal
• R3—NH—(CH2)mCOOR′ (V)
• wherein each R3 and R4 represents a hydrocarbon group having carbon atoms of from 2 to 30, and each R′, R″ and R′″ represents a hydrogen atom or a monovalent alkali metal, and each m, n and p represents an integer of from 1 to 10.
