(canceled)
An Atrorosin lake obtained by a method comprising:
- priming a metal to be amphoteric by making a hydroxide/oxide metal without use of NaCO3;
- coupling Atrorosin dye to ions of the metal by lowering a pH slowly to a value ranging from 3.5 to 4.5;
- phase separating precipitate and liquid;
- and
- reducing particle size, wherein at least 50-95% of the Atrorosin lake remains dispersed in water-based solution, wherein the Atrorosin dye is AtrorosinE dye, and wherein a ratio of Atrorosin to the metal is between 1:1 to 1:3 on a molar basis.

A solution comprising:
- water;
- and
- an Atrorosin lake dispersed in the water wherein the Atrorosin lake is obtained by a method comprising:
- priming a metal to be amphoteric by making a hydroxide/oxide metal without use of NaCO3;
- coupling Atrorosin dye to ions of the metal by lowering a pH slowly to a value ranging from 3.5 to 4.5;
