Abstract
A photosensitive mixture that contains a photosensitive compound, for example, a photoinitiator or a diazo compound, and a reaction product of a polymer containing active hydrogen with an olefinically unsaturated compound represented by the formula ##STR1## wherein X and Y are the same or different and denote oxygen or sulfur, PA0 R.sub.1 is an olefinically unsaturated aliphatic radical containing 2 to 8 carbon atoms and PA0 R.sub.2 is a saturated aliphatic radical containing 1 to 8 carbon atoms or an aryl radical containing 6 to 10 carbon atoms, is suitable for producing photoresists and printing plates.
