摘要： 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].(R.sub.1).sub.n --X--(OR.sub.2).sub.4-n (1)wherein R.sub.1 and R.sub.2 each represents an alkyl group or an aryl group; X represents Si, Al, ti, or Zr; and n represents an integer from 0 to 2.

摘要： A magnetic recording medium comprises a non-magnetic substrate, a thin ferromagnetic film layer overlaid on the substrate, and a polymer film formed by plasma polymerization. The thin ferromagnetic film layer is composed of ferromagnetic columnar grains. The polymer film is overlaid on the thin ferromagnetic film layer so as to permeate into the spaces between the ferromagnetic columnar grains, thereby improving the corrosion resistance and durability of the magnetic recording medium.
