A method for preparation of a lithographic printing plate including:
exposing with a laser a lithographic printing plate precursor including a
support and a photosensitive layer containing a sensitizing dye, a
radical polymerization initiator, a radical polymerizable compound and a
binder polymer; and subjecting the exposed lithographic printing plate
precursor to development processing with a developer having pH of from 3
to 9 to remove an unexposed area of the photosensitive layer, wherein the
binder polymer is a polymer having an acid value of from 10 to 250
mg-KOH/g and the developer contains a compound represented by one of the
formulae <1>, <2> and <3> defined herein.
