Abstract
Stabilized dye compositions comprising a dye of the formula ##STR1## OR A SALT THEREOF, WHEREIN EACH Me is copper or nickel, PA1 Y is optionally substituted arylcarbamoyl, PA1 Z is lower alkyl, or PA1 Y and Z taken together and with the carbon atoms to which they are joined form a naphthalene or heterocyclic ring, PA1 m is 1 to 3, and PA1 n is 1 or 2, PA2 With the proviso that the sum of m and n is 3 to 5, And, as a stabilizer therefor, an amino ether of the formula ##STR2## or a mixture thereof, WHEREIN R.sub.1 is hydrogen, alkyl of 1 to 3 carbon atoms or EQU --R.sub.8 --O--R.sub.9).sub.t' OH PA1 each R.sub.2 is hydrogen, alkyl of 1 to 3 carbon atoms or EQU --R.sub.8 --O--R.sub.9).sub.u' OH, PA1 r.sub.4 is hydrogen, alkyl of 1 to 3 carbon atoms or EQU --R.sub.8 --O--R.sub.9).sub.v' OH, PA1 each R.sub.5 is hydrogen, alkyl of 1 to 3 carbon atoms or EQU --R.sub.8 --O--R.sub.9).sub.w' OH, PA1 each R.sub.3, R.sub.6, R.sub.7, R.sub.8 and R.sub.9 is independently alkylene of 2 or 3 carbon atoms, PA1 p is 1 to 12, PA1 Each of r' and s' is independently 0 to 5, PA1 Each of t', u', v' and w' is independently 0 to 13, PA2 With the proviso that the sum of r' and s' is 0 to 5 and the sum of al…
