摘要:
A water-soluble dye for a color subtractive, lightfast, wide spectrum ink as follows:
wherein:
X is
R 1 is:
an aliphatic radical having from 1 to 18 carbon atoms; the radical
in which
R 2 is -H, -lower alkyl of 1 to 4 C atoms,
-lower alkoxy, -halogen, -N0 2 -CN, -C0 2 H;
R 3 is -H, -lower alkyl having 1 to 4 C atoms, -halogen, -C02H; M is H, Li, Na, K, -N(R 4 ) 4 in which R 4 is H, in which R 5 is -H, -lower alkyl, and n is 1 to 4; and in which
one of the -SO 3 M groups on the amino-naphthol radical is positioned meta or para to the -NH-group and the other -SO 3 M is meta to the -OH, and the dye in a water and glycol vehicle.
