    摘要： Radiation sensitive material suitable for the production of radiation sensitive plates for lithographic printing plate manufacture is based on a polymer including a plurality of structural units represented by the formula:
    in which, R represents H or CH₃; each R₁, which may be the same or different represents H or alkyl; R₂ represents a single bond or a substituted or unsubsti­tuted divalent radical; Ar represents a substituted or unsubstituted divalent radical derived from an aromatic or heteroaromatic compound; X represents O, S or NH; A represents an anion; Y represents a carbonyl oxy or aromatic radical; and n is an integer equal to or greater than 1.

    摘要： A light-sensitive adduct comprising the combination of a diazo resin having a plurality of pendant diazonium groups and a sulfonated polymer having a plurality of sulfonate groups and a presensitized light-sensitive article comprising a substrate having a light-sensitive coating which is comprised of the light-sensitive adduct on a surface thereof. After imagewise exposure, unexposed portions of the coating are removable by water or aqueous developers.
