Abstract
Chromophore-substituted vinyl-halomethyl-s-triazine compounds are provided capable of free-radical generation upon excitation with radiation having a wavelength of from about 330 to about 700 millimicrons.
Claims7
A compound having the formula ##EQU1## wherein Q is bromine or chlorine, P is --CQ.sub.3, --NH.sub.2, --NHR, --NR.sub.2, or --OR where R is phenyl or lower alkyl (lower alkyl herein meaning an alkyl group having no more than 6 carbon atoms);
- n is an integer from 1 to 3;
- and W is an optionally substituted aromatic or heterocyclic nucleus or ##EQU2## where Z is oxygen or sulfur and R.sup.1 is hydrogen, a lower alkyl or phenyl group, said compound being capable on stimulation by actinic radiation at a wavelength of about 330 to about 700 millimicrons of generating free radicals.
A compound having the formula:
- ##STR19##
A s-triazine having at least one ring-substituted trihalomethyl group selected from the class consisting of --CCl.sub.3 and --CBr.sub.3, and at least one chromophoric moiety conjugated with the triazine ring by ethylenic unsaturation, said moiety being capable of imparting to said s-triazine the ability to generate halogen-free radicals on stimulation by actinic radiation having a wave length of about 330 to about 700 millimicrons.
A s-triazine having at least one ring-substituted trihalomethyl group selected from the class consisting of --CCl.sub.3 and --CBr.sub.3, and at least one moiety conjugated with the triazine ring by ethylenic unsaturation, said moeity beng an optionally substituted aromatic or heterocyclic nucleus or ##STR20## wherein Z is oxygen or sulfur and R.sub.1 is hydrogen, a lower alkyl or phenyl group, and said moiety being capable of imparting to said s-triazine the ability to generate halogen-free radicals on stimulation by actinic radiation having a wave length of about 330 to about 700 millimicrons.
A compound having the formula ##STR21## wherein Q is bromine or chlorine, P is --CQ.sub.3, --NH.sub.2, --NHR, --NR.sub.2, or --OR where R is phenyl or lower alkyl, n is an integer from 1 to 3, and W is an optionally substituted phenyl, pyrryl, benzopyrryl, oxazoyl, benzoxanzoyl, benzthiozoyl, or ##STR22## where Z is oxygen or sulfur and R.sub.1 is hydrogen, a lower alkyl, or a phenyl group, said compound being capable of generating free radicals on stimulation by actinic radiation at a wave length of about 330 to about 700 millimicrons.
