ABSTRACT:
A radiation-sensitive planographic printing plate which is excellent in terms of durability wherein development with water, or direct production of the plate from digital data through infrared laser recording in particular such that a special process is not necessary, is possible, by forming on a support a photosensitive layer containing a reaction product of a compound having in a molecule thereof a functional group X and a functional group Y and a compound represented by a formula (1) stated below, or alternatively, containing a polymerization product of a compound having the functional group X and a compound represented by the formula (1) stated below. Further by incorporating water-insoluble particles in this photosensitive layer, many voids are formed in the photosensitive layer, further improving sensitivity and discrimination. The functional group X is a group selected from among a sulfonic acid ester group, a disulfone group, a sulfonimide group, and an alkoxyalkyl ester group and the functional group Y is a group selected from among --OH, --NH.sub.2, --COOH, --NH--CO--R.sub.3, and --Si(OR.sub.4).sub.3 [wherein R.sub.3 and R.sub.4 each represents an alkyl group or an aryl group].
