1. A polymer which has a mean molecular weight of not less than 1000 and which contains, in side chains, thioxanthone groupings of the formula I'"'"' ##STR63## in which n is the number 1 or 2, X is hydrogen, halogen, --CN, --OH, --SH, --NH2, --NO2, phenylsulfonyl or alkylsulfonyl, alkyl, alkoxy, alkylthio, N,N-dialkylamino or --CO-alkyl having, in each case, 1-4C atoms in the alkyl moieties, Z is hydrogen, halogen, --OH, --SH or alkyl, alkoxy, alkylthio or N,N-dialkylamino having, in each case, 1-4C atoms in the alkyl moieties, Y is --OR1 --, --SR1 -- or --N(R2)R1 --, R1 is straight-chain or branched alkylene having a total of 2-23C atoms and 2-13C atoms in the main chain, cyclopentylene, cyclohexylene, phenylene ##STR64## or --(CH2 CH2 O)x --CH2 CH2 --, R2 is hydrogen or straight-chain or branched alkyl having a total of 1-23C atoms and 1-13C atoms in the main chain, G is --CH2 --, --CH2 CH2 --, --C(CH3)2 --, --O--, --SO2 -- or --NH-- and x is an integer from 1 to 5, the proportion of groupings of the formula I'"'"' being not less than 2 percent, based on the number of recurring structural elements in the polymer.
