The present invention provides compounds having the formula: in which R is hydrogen, hydroxy, halogen, C<SUB>1</SUB>-C<SUB>20</SUB>-alkyl, C<SUB>4</SUB>-C<SUB>12</SUB>cycloalkyl, C<SUB>2</SUB>-C<SUB>20</SUB>alkenyl, C<SUB>2</SUB>-C<SUB>20</SUB>alkynyl, C<SUB>1</SUB>-C<SUB>20</SUB>-alkoxy, C<SUB>4</SUB>-C<SUB>12</SUB>cycloalkoxy, C<SUB>2</SUB>-C<SUB>20</SUB>alkenoxy, C<SUB>2</SUB>-C<SUB>20</SUB>alkynoxy or C<SUB>7</SUB>-C<SUB>13</SUB>aralkyl; R<SUB>1 </SUB>and R<SUB>2</SUB>, independently, are hydrogen, C<SUB>1</SUB>-C<SUB>20</SUB>alkyl, C<SUB>4</SUB>-C<SUB>12</SUB>cycloalkyl, C<SUB>7</SUB>-C<SUB>13 </SUB>aralkyl, -C(-O)-R<SUB>4 </SUB>(in which R<SUB>4 </SUB>is C<SUB>1</SUB>-C<SUB>20</SUB>alkyl, C<SUB>2</SUB>-C<SUB>20</SUB>alkyl interrupted by 1 to 6 oxygen atoms, hetero-substituted C<SUB>1</SUB>-C<SUB>20</SUB>alkyl, C<SUB>4</SUB>-C<SUB>12</SUB>cycloalkyl, C<SUB>2</SUB>-C<SUB>20</SUB>alkenyl, C<SUB>2</SUB>-C<SUB>20</SUB>alkynyl, C<SUB>1</SUB>-C<SUB>20</SUB>-alkoxy, C<SUB>4</SUB>-C<SUB>12</SUB>cycloalkoxy, C<SUB>2</SUB>-C<SUB>20</SUB>alkenoxy, C<SUB>2</SUB>-C<SUB>20</SUB>alkynoxy, C<SUB>6</SUB>-C<SUB>12 </SUB>aryl, C<SUB>6</SUB>-C<SUB>12 </SUB>aryloxy or C<SUB>7</SUB>-C<SUB>13 </SUB>aralkyl), or -C(-O)-NH-R<SUB>1 </SUB>in which R<SUB>1 </SUB>has its previous significance; and R<SUB>3 </SUB>is hydrogen, halogen, hydroxy, C<SUB>1</SUB>-C<SUB>20</SUB>alkyl, C<SUB>4</SUB>-C<SUB>12</SUB>cycloalkyl, C<SUB>2</SUB>-C<SUB>20</SUB>alkenyl, C<SUB>2</SUB>-C<SUB>20</SUB>alkynyl, C<SUB>1</SUB>-C<SUB>20</SUB>-alkoxy, C<SUB>4</SUB>-C<SUB>12</SUB>cycloalkoxy, C<SUB>2</SUB>-C<SUB>20</SUB>alkenoxy, C<SUB>2</SUB>-C<SUB>20</SUB>alkynoxy, phenyl, C<SUB>7</SUB>-C<SUB>13 </SUB>aralkyl or -N(R<SUB>1</SUB>)(R<SUB>2</SUB>) in which R<SUB>1 </SUB>and R<SUB>2 </SUB>have their previous significance, or R<SUB>1 </SUB>and R<SUB>2 </SUB>together form a C<SUB>4</SUB>-C<SUB>12 </SUB>membered ring. The new triphenyltriazine compounds have improved absorption spectrum characteristics and superior resistance to exposure to UV light, relative to known triphenyltriazine compounds.
