Provided are, as a lithographic printing plate precursor that enables good development with a developer having a pH from 2 to 10 and is excellent in runlength and stain resistance and a production process of a lithographic printing plate using the precursor, a lithographic printing plate precursor whose photosensitive layer contains the following components (A), (B), and (C):
(A) a copolymer having a repeating unit of the formula (1) and at least one of a repeating unit of the formula (2) and a repeating unit of the formula (3):
wherein each of A and B independently represents a hetero atom, each of R and R 1 to R 9 represents a monovalent substituent, L represents a divalent linking group, X represents a hydroxyl group, a monovalent group containing an acid group, an alkyleneoxy group, an amide group, or an ether group, an amino group, an ammonium group, or a salt obtained by neutralizing an acid group, and L 0 represents a single bond or divalent hydrocarbon group,
(B) a compound having an ethylenically unsaturated bond, and
(c) a polymerization initiator; and a production process of a lithographic printing plate by using the precursor. |
