<p>Novel thioxanthones substituted by .alpha.-aminoalkyl groups The novel thioxanthones of the formula I < IMG > (I) in which X is hydrogen, chlorine, bromine, C1-4-alkyl or C1-6-alkoxy, R1 is hydrogen, C1-6-alkyl, phenyl, -COOCH3 or -COOC2H5 and R2 is hydrogen, C1-6-alkyl, -COOCH3 or -COOC2H5, or R1 and R2 together are -(CH2)e-, where e = 4 or 5, and W is hydrogen or -COOC1-4-alkyl, are suitable, for example, for the preparation of photosensitive compositions of matter which are capable of undergoing condensation or addition reactions and may or may not be crosslinkable, and which in turn are used for image formation, in particular by means of electroless deposition of metals. Such compositions of matter contain, for example, a thioxanthone of the formula I, an oligomer or polymer with terminal glycidyl groups and, where relevant, a crosslinking agent and/or a salt of a metal of group Ib or VIII of the Periodic Table.</p> |
