Abstract
The invention describes light-sensitive bis-trichloromethyl-s-triazines of the general formula I ##STR1## wherein A denotes the ring members required to complete a 5- or 6-membered heterocyclic ring which may be substituted or may carry a substituted or unsubstituted fused benzene ring, R denotes a substituted or unsubstituted alkyl group and X denotes CH or N. The compounds are readily prepared in high yields. They are suitable for use as light-sensitive free-radical and acid donors in light-sensitive compositions.
Claims21
A light-sensitive bis-trichloromethyl-s-triazine having the formula I ##STR6## wherein A are the ring members required to complete a 5- or 6-membered heterocyclic ring, wherein said ring members may be unsubstituted or substituted with an alkyl or alkoxy group containing 1 to 6 carbon atoms, an aryl or aryloxy group containing 6 to 10 carbon atoms or a halogen atom, wherein said heterocyclic ring may be fused to a benzene or naphthalene ring, and wherein said fused benzene or naphthalene ring may be unsubstituted or substituted with an alkyl or alkoxy group containing 1 to 6 carbon atoms, an aryl or aryloxy group containing 6 to 10 carbon atoms or a halogen atom
- is an alkyl group unsubstituted or substituted with an alkoxy group having 1 to 6 carbon atoms, an aryl or aryloxy group having 7 to 10 carbon atoms or halogen, and
- X is CH or N.
A light-sensitive bis-trichloromethyl-s-triazine having the formula I ##STR7## wherein A are the ring members required to complete a 5- or 6-membered heterocyclic ring, wherein said ring members may be unsubstituted or substituted with an alkyl or alkoxy group containing 1 to 6 carbon atoms, an aryl or aryloxy group containing 6 to 10 carbon atoms or a halogen atom wherein said heterocyclic ring may be fused to a benzene or naphthalene ring, and wherein said fused benzene or naphthalene ring may be unsubstituted or substituted with an alkyl or alkoxy group containing 1 to 6 carbon atoms, an aryl or aryloxy group containing 6 to 10 carbon atoms or a halogen atom, with the proviso that A contains at least one heteroatom selected from the group consisting of S, Se, O, and N, wherein the additional heteroatom is in a 1,3 relationship to the N that is already present in the ring,
- R is an alkyl group unsubstituted or substituted with an alkoxy group having 1 to 6 carbon atoms, an aryl or aryloxy group having 7 to 10 carbon atoms, or halogen, and
- X is CH or N.
