Photocrosslinkable polymers with side groups derived from indenone and the preparation and use of these polymers

摘要

The invention relates to polymers which are crosslinkable under the action of light and contain side groups of the formula in which R3 is preferably chlorine and R, R1 and R2 are, for example, H or -CH3. The proportion of these groups in the polymers is preferably 20 to 100%. Because of their high sensitivity to light, the polymers are suitable for photographic applications.
