Abstract:
A photoactivatable composition comprisinga) at least one compound that can be crosslinked under the action of an acid and/orb) at least one compound the solubility of which is altered under the action of an acid andc) as photoinitiator, at least one compound of formula I ##STR30## m is 0 or 1 and x is 1 or2; R.sub.1 is phenyl substituted by one or more of the radicals OR.sub.4 andlor SR.sub.4 it being possible for the substituents OR.sub.4 and SR.sub.4 to form 5- or 6-membered rings, via the radicals R.sub.4 or with one of the carbon atoms of the phenyl ring, with the proviso that when the phenyl ring is substituted by methoxy at least one further substituent must be present on the ring, or R.sub.1 is naphthyl, anthracyl or phenanthryl, the radicals naphthyl, anthracyl and phenanthryl being substituted by OR4 and/or SR.sub.4, it being possible for the substituents OR4 and SR.sub.4 to form 5- or 6-membered rings, via the radicals R.sub.4, or with one of the carbon atoms of the naphthyl, anthracyl or phenanthryl ring, or R.sub.1 is a heteroaryl radical that is substituted by OR.sub.4 and/or SR.sub.4 it being possible for the substituents OR.sub.4 and SR.sub.4 to form 5- or 6-membered rings, via the radicals R.sub.4, or with one of the carbon atoms of the heteroaryl ring,R.sub.2 is C.sub.2 -C.sub.6 alkoxycarbonyl, CN, C.sub.1 -C.sub.4 haloalkyl, S(O).sub.n C.sub.1 -C.sub.6 alkyl, or unsubstituted or C.sub.1 -C.sub.12 alkyl-substituted S(O)n-C.sub.6 -C.sub.12 aryl, wherein n is 1 or 2; or R.sub.1 and R.sub.2, if appropriate together with the CO group, form a 5- or 6-membered ring that is substituted by OR.sub.4 or SR.sub.4 and that may additionally be interrupted by 0, S, NR.sub.5 and/or by CO and to which one or more benzo radicals may be fused;R.sub.3, when x is 1, is C.sub.1 -C.sub.18 alkyl, phenyl-C.sub.1 -C.sub.3 alkyl, camphoryl, C.sub.1 -C.sub.10 haloalkyl, phenyl, naphthyl, anthracyl or phenanthryl, the radicals phenyl, naphthyl, anthracyl and phenanthryl being unsubstituted or substituted by one or more of the radicals halogen, C.sub.1 -C.sub.4 haloalkyl, CN, NO.sub.2, C.sub.1 -C.sub.16 alkyl, phenyl, OR.sub.4, COOR.sub.7, --OCO--C.sub.1 -C.sub.4 alkyl, SO.sub.2 OR.sub.7 and/or by R.sub.5 R.sub.6 N, or R.sub.3, when x is 2, is C.sub.2 -C.sub.12 alkylene, phenylene, naphthylene, ##STR31## diphenylene or oxydiphenylene, the radicals phenylene, naphthylene, ##STR32## diphenylene and oxydiphenylene being unsubstituted or substituted by C.sub.1 -C.sub.12 alkyl;R.sub.4 is hydrogen, C.sub.1 -C.sub.12 alkyl that is unsubstituted or substituted by phenyl, OH, C.sub.1 -C.sub.12 alkoxy, C.sub.1 -C.sub.12 alkylsulfonyl, phenylsulfonyl, (4-methylphenyl)sulfonyl and/or by C.sub.2 -C.sub.6 alkanoyl and that may additionally be interrupted by --O--, or R.sub.4 is phenyl;R.sub.5 and R.sub.6 are each independently of the other hydrogen or C.sub.1 -C.sub.12 alkyl that is unsubstituted or substituted by OH, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.12 alkylsulfonyl, phenylsulfonyl, (4-methylphenyl)-sulfonyl and/or by C.sub.1 -C.sub.6 alkanoyl and that may additionally be interrupted by --O--, or R.sub.5 and R.sub.6 are phenyl, C.sub.2 -C.sub.6 alkanoyl, benzoyl, C.sub.1 -C.sub.6 alkylsulfonyl, phenylsulfonyl, (4-methylphenyl)sulfonyl, naphthylsulfonyl, anthracylsulfonyl or phenanthrylsulfonyl, or R.sub.5 and R.sub.6, together with the nitrogen atom to which they are bonded, form a 5-, 6- or 7-membered ring which may be interrupted by --O-- or by --NR.sub.4 --; and R.sub.7 is C.sub.1 -C.sub.12 alkyl that is unsubstituted or substituted by OH and/or by C.sub.1 -C.sub.4 alkoxy and that may additionally be interrupted by --O--.
