Abstract: \\ Hoe 78/K 065 LIGHT-SENSITIVE MIXTURE AND COPYING MATERIAL PRODUCED THEREFROM A positive-working light-sensitive copying material, in particular for the preparation of planographic printing plates, is described, the light-sensitive layer of which contains an ester or amide of a o-naphthoquinone diazide-sulfonic or -carboxylic acid, an alkali-soluble, water-insoluble phenolic resin and a condensation product of a hydroxybenzophenone and formaldehyde. The material is distinguished by an increased light-sensitivity.

Abstract: A light-sensitive mixture is described, which is specially intended for the production of planographic printing plates and which contains, as the light-sensitive compound, a naphthoquinonediazide sulfonic acid ester of the general formula I in which D is the 1,2-naphthoquinone-2-diazide-5-sulfonyl radical or the 1,2-naphthoquinone-2-diazide-4-sulfonyl radical, preferably the 1,2-naphthoquinone-2-diazide-5-sulfonyl radical, R and R' are hydrogen atoms, alkyl groups having 1 to 4 carbon atoms or radicals of the formula DO, and n denotes an integer from 6 to 18, preferably from 8 to 14. The new compounds are distinguished by good solubility and produce layers which have a high resistance to alkaline developer solutions and to damping solution containing alcohol.

Abstract: A light-sensitive mixture is described, which contains, as the light-sensitive compound, a 1,2-naphthoquinone-2-diazidesulfonic acid ester of the general formula I (I) in which R and R' denote hydrogen atoms or lower alkyl groups, X denotes a saturated alkylene, hydroxyalkylene or dihydroxyalkylene group having 6 to 18 carbon atoms, D denotes the 1,2-naphthoquinone-2-diazide-5-sulfonyl radical or the 1,2-naphthoquinone-2-diazide-4-sulfonyl radical and n denotes a number from 1 to 20. The new quinone diazides produce printing plates which are capable of long printing runs and have good resistance to developer and good flexibility of the printing stencil.
