    摘要: Lithographic printing plates and processes for preparing the lithographic printing plates are provided. The plates have excellent printing durability, staining resistance and staining resistance over time. The lithographic printing plate precursor includes: a substrate; a photosensitive layer provided on the substrate; and an extra layer optionally provided between the substrate and the photosensitive layer. The photosensitive layer or the extra layer adjacent to the substrate contains (A) a copolymer. The copolymer (A) includes: (a1) a repeating unit of formula (a1-1) below in a side chain, and (a2) a repeating unit having at least one of the structures represented by formulae (a2-1) to (a2-6) shown in the specification in a side chain. L1, Z1, R1, and R21, R22 and R23 in formula (a1-1) and the variables in formulae (a2-1) to (a2-6) are as defined in the specification.
