  • Processing of radiation sensitive plates
    Patent number: 4350756
    Abstract: A developer for processing image-wise exposed negative-working radiation sensitive plates based on organic solvent soluble diazo resins or certain photocrosslinkable resins or photopolymerizable olefinically unsaturated compounds includes a surfactant and a salt of an aliphatic carboxylic acid containing up to nine carbon atoms.
