Abstract:
1. A compound of the formula wherein R 1 is (i) a linear or branched alkylene group, which can be saturated or unsaturated, and substituted or unsubstituted alkylene groups, and wherein hetero atoms either may or may not be present in the alkylene group, (ii) an arylene group, which can be substituted or unsubstituted arylene groups, and wherein hetero atoms either may or may not be present in the arylene group, (iii) an arylalkylene group, which can be substituted or unsubstituted arylalkylene groups, wherein the alkyl portion of the arylalkylene group can be linear or branched, saturated or unsaturated, and cyclic or acyclic, and wherein hetero atoms either may or may not be present in either the aryl or the alkyl portion of the arylalkylene group, or (iv) an alkylarylene group, which can be substituted or unsubstituted alkylarylene groups, wherein the alkyl portion of the arylalkylene group can be linear or branched, saturated or unsaturated, and cyclic or acyclic, and wherein hetero atoms either may or may not be present in either the aryl or the alkyl portion of the alkylarylene group, R 2 and R 2 ′ each, independently of the other, are (i) alkylene groups, which can be linear or branched, saturated or unsaturated, cyclic or acyclic, and substituted or unsubstituted alkylene groups, and wherein hetero atoms either may or may not be present in the alkylene group, (ii) arylene groups, which can be substituted or unsubstituted arylene groups, and wherein hetero atoms either may or may not be present in the arylene group, (iii) arylalkylene groups, which can be substituted or unsubstituted arylalkylene groups, wherein the alkyl portion of the arylalkylene group can be linear or branched, saturated or unsaturated, and cyclic or acyclic, and wherein hetero atoms either may or may not be present in either the aryl or the alkyl portion of the arylalkylene group, or (iv) alkylarylene groups, which can be substituted or unsubstituted alkylarylene groups, wherein the alkyl portion of the alkylarylene group can be linear or branched, saturated or unsaturated, and cyclic or acyclic, and wherein hetero atoms either may or may not be present in either the aryl or the alkyl portion of the alkylarylene group, R 3 and R 3 ′ each, independently of the other, are either (a) photoinitiating groups, or (b) groups which are (i) alkyl groups, which can be linear or branched, saturated or unsaturated, cyclic or acyclic, and substituted or unsubstituted alkyl groups, and wherein hetero atoms either may or may not be present in the alkyl group, (ii) aryl groups, which can be substituted or unsubstituted aryl groups, wherein hetero atoms either may or may not be present in the aryl group, (iii) arylalkyl groups, which can be substituted or unsubstituted arylalkyl groups, wherein the alkyl portion of the arylalkyl group can be linear or branched, saturated or unsaturated, and cyclic or acyclic, and wherein hetero atoms either may or may not be present in either the aryl or the alkyl portion of the arylalkyl group, or (iv) alkylaryl groups, which can be substituted or unsubstituted alkylaryl groups, wherein the alkyl portion of the alkylaryl group can be linear or branched, saturated or unsaturated, and cyclic or acyclic, and wherein hetero atoms either may or may not be present in either the aryl or the alkyl portion of the alkylaryl group, provided that at least one of R 3 and R 3 ′ is a photoinitiating group, and X and X′ each, independently of the other, is an oxygen atom or a group of the formula —NR 4 —, wherein R 4 is (i) a hydrogen atom, (ii) an alkyl group, which can be linear or branched, saturated or unsaturated, cyclic or acyclic, and substituted or unsubstituted alkyl groups, and wherein hetero atoms either may or may not be present in the alkyl group, (iii) an aryl group, which can be substituted or unsubstituted aryl groups, and wherein hetero atoms either may or may not be present in the aryl group, (iv) an arylalkyl group, which can be substituted or unsubstituted arylalkyl groups, wherein the alkyl portion of the arylalkyl group can be linear or branched, saturated or unsaturated, and cyclic or acyclic, and wherein hetero atoms either may or may not be present in either the aryl or the alkyl portion of the arylalkyl group, or (v) an alkylaryl group, which can be substituted or unsubstituted alkylaryl groups, wherein the alkyl portion of the alkylaryl group can be linear or branched, saturated or unsaturated, and cyclic or acyclic, and wherein hetero atoms either may or may not be present in either the aryl or the alkyl portion of the alkylaryl group.
