Abstract
A radiation-sensitive mixture which contains a polymeric binder having acid-labile side groups and a compound which generates a strong acid on irradiation wherein the binder is a polymer built up from novel amides of .alpha.,.beta.-unsaturated carboxylic acids, is highly sensitive in the shortwave uv region and useful in the production of recording material.
Claims21
A polymer comprising units of the formula (I) ##STR4## in which R.sup.1 is an acid-labile protecting group,
- R.sup.2 is (C.sub.1 -C.sub.4)-alkyl, halogenated-(C.sub.1 -C.sub.4)-alkyl, halogen, CN, or hydrogen,
- R.sup.3,4,5,6 independently of one another are aliphatic, araliphatic or aromatic radicals each independently having 1 to 20 carbon atoms and each being unsubstituted or halogen substituted, halogen, hydroxyl or hydrogen,
- R.sup.7 is a hydrogen atom or a (C.sub.1 -C.sub.4)-alkyl group, and
- R.sup.8 and R.sup.9 are identical or different and are hydrogen, a (C.sub.1 -C.sub.6)-alkyl group or a (C.sub.6 -C.sub.10)-aryl group.
