A positive radiation-sensitive recording material containing the radiation-sensitive polymer is also disclosed.
Claims46
A radiation-sensitive polymer, comprising:
- (a) units having side groups of the general formula I ##STR8## and (b) units having radiation-sensitive side groups of the general formula II ##STR9## wherein the numerical ratio of units (a) to units (b) is about 98:2 to 0:100, and
- wherein
- R is an acyclic, isocyclic or heterocyclic radical having 3 to 20 carbon atoms,
- X is a (C.sub.1 -C.sub.6)alkyl, (C.sub.1 -C.sub.6)alkoxy-(C.sub.1 -C.sub.6)alkyl, carboxyl, formyl, (C.sub.1 -C.sub.15)alkoxycarbonyl, (C.sub.2 -C.sub.5)alkanoyl or (C.sub.1 -C.sub.6)alkoxy group or a halogen atom,
- m is 0, 1 or 2, it being possible for the radicals X to differ if m=2, and
- n is 1 or 2, it being possible for the radicals R to differ if n=2.
