Patent ID: 7183038

Claim:
A lithographic printing plate precursor comprising an image-forming layer containing a polymerization initiator and a polymerizable compound, and a hydrophilic support, wherein the lithographic printing plate precursor comprises a compound containing at least one functional group having an interaction with a surface of the hydrophilic support, and wherein the compound containing the at least one functional group having an interaction with the surface of the hydrophilic support is one of a phosphonic acid represented by the following formula (I) and a phosphoric acid amide represented by the following formula (II): wherein R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 and R 9 each independently represents a hydrogen atom, a halogen atom or an alkyl group; X 1 and X 2 each independently represents an oxygen atom, a sulfur atom or an imino; Y 1 represents a connecting group having a valence of (n1+1); Y 2 represents a connecting group having a valence of (n2+1); and n1 and n2 each independently represents a number of 1, 2 or 3.
