Photosensitive composition

摘要

The invention relates to a photosensitive composition containing a) a high-molecular-weight compound prepared by polymerisation of at least one polymerisable unit of the formula (I) below and b) a positive-working photosensitive substance <IMAGE> in which: A is a hydrogen atom, a halogen atom or an alkyl group; X is an oxygen atom, NH or N-R5, in which R5 is an alkyl group; and R1, R2, R3 and R4, which are identical or different, are each a hydrogen atom, a halogen atom, an alkyl group, a substituted alkyl group, an aryl group, a substituted aryl group, -OR6, -OCO-R7, -NHCO-R8, -NHCONHR9, -OCONHR10, -CO-OR11, -CONHR12, -COR13, -CONR14R15, -CN or -CHO; or in which two of the radicals R1, R2, R3 and R4 can be combined with one another to form a ring, where R6, R7, R8, R9, R10, R11, R12, R 13, R14 and R15, which are identical or different, are in each case an alkyl group, a substituted alkyl group, an aryl group or a substituted aryl group, with the proviso that at least one of the radicals R1, R2, R3 and R4 is a substituent other than a hydrogen atom.
