Abstract
Abstract This invention relates to a radiation sensitive composition which comprises, as the radiation sensitive compound, an s-triazine corresponding to Formula I ##STR1## wherein X is bromine or chlorine, and m and n are whole numbers from 0 to 3 which, taken together, do not exceed 5, and in which R is a substituted or unsubstituted bi- or polynuclear aromatic or heterocyclic aromatic group which may be partially hydrogenated and which is linked via an unsaturated nuclear carbon atom.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
117 words
A radiation sensitive composition which comprises an ethylenically unsaturated compound capable of undergoing a polymerization reaction initiated by free radicals or a compound whose solubility is changed by the action of an acid and, as the radiation sensitive compound, from about 0.05 to 10 percent, based on the solids content of the composition, of an s-triazine corresponding to Formula I ##STR4## wherein X is bromine or chlorine, and m and n are whole numbers from 0 to 3, which, taken together, do not exceed 5, and in which R is a substituted or unsubstituted bi- or polynuclear aromatic or heterocyclic aromatic group which may be partially hydrogenated and which is linked via an unsaturated nuclear carbon atom.
Claim 2
Dependent Claim
117 words
A radiation sensitive composition which comprises an ethylenically unsaturated compound capable of undergoing a polymerization reaction initiated by free radicals or a compound whose solubility is changed by the action of an acid and, as the radiation sensitive compound, from about 0.05 to 10 percent, based on the solids content of the composition, of an s-triazine corresponding to Formula I ##STR4## wherein X is bromine or chlorine, and m and n are whole numbers from 0 to 3, which, taken together, do not exceed 5, and in which R is a substituted or unsubstituted bi- or polynuclear aromatic or heterocyclic aromatic group which may be partially hydrogenated and which is linked via an unsaturated nuclear carbon atom.
Claim 3
Dependent Claim
37 words
