<P>PROBLEM TO BE SOLVED: To provide a photosensitive composition superior in development, sensitivity and printing durability when using as an image forming layer of an original plate of a planographic printing plate, and to provide the original plate of the planographic printing plate, and a planographic printing method therefor. <P>SOLUTION: The photosensitive composition contains a compound expressed by general formula (1), (2) or (3). In the formula, a cation part is a part comprising a functional group having (+) charge, an anion part is a part comprising a functional group having (-) charge, X<SP>n-</SP>is an n valence of an anion compound, M<SP>q+</SP>is a q valence of a cation compound, a and b are natural numbers of 1 to 20 respectively, m, n, p, and q are natural numbers of 1 to 6, respectively, A is a number being m/An=1, B is a number being p/Bq=1, and C is a number being m/Cp=1. <P>COPYRIGHT: (C)2008,JPO&INPIT |
