<p>Triphenodioxazine dyes which, in the free acid form, have the formula:
<Chemistry id="chema01" num="0001"><Image id="ia01" he="31" wi="96" file="IMGA0001.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein A is Cl or Br;
<UnorderedLists id="ula01" listStyle="none"><ListItem>Y is cyclo pentylene, cyclohexylene or (CH<Sub>2</Sub>)x where x is 2, 3 or 4; and</ListItem><ListItem>Z is NRCO<Sub>2</Sub>R<Sup>1</Sup> or
<Chemistry id="chema02" num="0002"><Image id="ia02" he="17" wi="43" file="IMGA0002.TIF" imgContent="chem" imgFormat="TIFF" inline="no" /></Chemistry>wherein R is H, optionally substituted alkyl or optionally substituted aryl;</ListItem><ListItem>R' is optionally substituted alkyl, optionally substituted cycloalkyl or optionally substituted aryl; and</ListItem><ListItem>R<Sup>2</Sup> is CH=CH-, CH=CH-<Sub>C</Sub>H<Sub>2</Sub>-, (CH<Sub>2</Sub>)<Sub>-2-4</Sub> or a 1,2-radical of a 5 or 6 membered carbocyclic compound;</ListItem></UnorderedLists>
or, when Y is cyclopentylene or cyc/ohexylene, Z may also be H or alkyl, alkoxy, aryl, aryloxy, cycloalkyl, cycloalkoxy or amino, all of which may be optionally substituted.<!-- EPO <DP n="2"> --></p> |
