Title of Invention

PHOTOACTIVABLE NITROGEN BASES

Abstract Compounds of the formula 1 R<SUB>1</SUB> is an aromatic or heteroaromatic radical which is capable of absorbing light in the wave- length range from 200 nm to 650 nm and which is unsubstituted or substituted one or more times by C<SUB>1</SUB>-C<SUB>18</SUB>alkyl, C<SUB>2</SUB>-C18alkenyl, C<SUB>2</SUB>-C<SUB>1</SUB>alkynyl, C<SUB>1</SUB>-C<SUB>18</SUB>haloalkyl, NO<SUB>2</SUB>, NR<SUB>10</SUB>R<SUB>11</SUB>, CN, OR<SUB>12</SUB>, SR<sub>12</sub>,C(O)R<sub>13</sub>,C(O)OR<sub>14</sub>, halogen OR radical of the formula II which on absorption brings about a photoelimination which leads to the generation of an amidine group, R<SUB>2</SUB> and R<SUB>3</SUB> independently of one another are hydrogen, C<SUB>1</SUB>-C<SUB>18</SUB>salkyl or phenyl which is unsubstituted or is substituted one or more times by C<SUB>1</SUB>-C<SUB>18</SUB>salkyl, CN, OR<SUB>12</SUB>, SR<SUB>12</SUB>, halogen or C<SUB>1</SUB>-C<SUB>18</SUB>haloalkyl; R<SUB>5</SUB> is C<SUB>1</SUB>-C<SUB>18</SUB>salkyl or NR<SUB>8</SUB>R<SUB>9</SUB>; R<SUB>4</SUB>, R<SUB>6</SUB>, R<SUB>7</SUB>, R<SUB>8</SUB>R<SUB>9</SUB>R<SUB>10</SUB> and R<SUB>11</SUB> independently of one another are hydrogen or C<SUB>1</SUB>-C<SUB>18</SUB>salkyl; or R<SUB>4</SUB> and R<SUB>6</SUB> together form a C<SUB>2</SUB>-C<SUB>12</SUB>alkylene bridge which is unsubstituted or is substituted by one or more C<SUB>1</SUB>-C<SUB>4</SUB>alkyl radicals; or R<SUB>5</SUB> and R<SUB>7</SUB>, independently of R<SUB>4</SUB> and R<SUB>6</SUB>, together form a C<SUB>2</SUB>-C<SUB>12</SUB>alkylene bridge which is unsubstituted or is substituted by one or more C<SUB>1</SUB>-C<SUB>4</SUB>alkyl radicals; or, if R<SUB>5</SUB> is a radi- cal NR<SUB>8</SUB>R<SUB>9</SUB> R<SUB>7</SUB>and R<SUB>9</SUB> together form a C<SUB>2</SUB>- C<SUB>12</SUB>-Cvalkylene bridge which is unsubstituted or is sub- stituted by one or more C<SUB>1</SUB>-C<SUB>4</SUB>alkyl radicals; and R<SUB>12</SUB> R<SUB>13</SUB> and R<SUB>14</SUB> independently of one an- other are hydrogen or C<SUB>1</SUB>-C<SUB>18</SUB>salkyl; are suitable as photoinitiators for compounds which react under base catalysis.
