Abstract:
A photocurable silicone of the formula:MD.sub.n D.sup.E.sub.m-p D*.sub.p M,wherein M is selected from the group consisting of R.sub.3 SiO.sub.1/2 and R.sub.2 ESiO.sub.1/2 ; where each R is independently selected from the group consisting of monovalent alkyl hydrocarbon radicals having from one to about thirty carbon atoms, monovalent alkenyl hydrocarbon radicals having from two to about thirty carbon atoms, monovalent alkynyl hydrocarbon radicals having from two to about thirty carbon atoms, monovalent aryl hydrocarbon radicals having from six to about thirty carbon atoms, monovalent alkylaryl hydrocarbon radicals having from seven to about thirty carbon atoms, monovalent halogen substituted alkyl hydrocarbon radicals having from one to about thirty carbon atoms, monovalent halogen substituted alkenyl hydrocarbon radicals having from two to about thirty carbon atoms, monovalent halogen substituted alkynyl hydrocarbon radicals having from two to about thirty carbon atoms, monovalent halogen substituted aryl hydrocarbon radicals having from six to about thirty carbon atoms, and monovalent halogen substituted alkylaryl hydrocarbon radicals having from seven to about thirty carbon atoms, and where E is an epoxide functionalized substituted or unsubstituted hydrocarbon group;D has the formula R.sub.2 SiO.sub.2/2, where each R is as previously defined and is independently selected;D.sup.E has the formula RESiO.sub.2/2, where R is as previously defined and where E is an epoxide functionalized substituted or unsubstituted hydrocarbon group;D* is defined as the reaction product of D.sup.E with a compound selected from the group consisting of R'COOH, (R'CO).sub.2 O, R'COX, R'SO.sub.3 H, and R'SO.sub.2 X, where R' is a photosensitizing naphthyl group selected from the Group consisting of naphthyl, naphthyloxy, hydroxynaphthyl, hydroxynaphthyloxy and substituted naphthyl, wherein the substituted naphthyl has at least one substituent selected from the group consisting of hydroxyl, halogen, and alkyl having from 1 to 10 carbon atoms; and X is a halogen; andthe subscripts n, m, and p are integers where the sum of n+m+p is in the range from about 10 to about 2,000 whereby said silicone is photo-sensitizing.
