摘要
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 IMAGE (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.
