Abstract

The following formulation provides an orange leucodye of the general type shown in U.S. Patent 4,309,255. It is noted that orange is akin to combining a red and yellow dye, and it gives the possibility of a two-component black dye (blue plus orange). 5H-6-chloro-benzo(a)phenothiaz-5 -one 1, and the leuco form is 12H-6-chloro-5-hydroxybenzo(a)phenothiazine 2. The formula of the dye material is: where R is a member selected from the group consisting of hydrogen, CH3O-, COOHCOO-, and COOHR1COO-, where R1 is a saturated or unsaturated alkyl group containing from 2 to 4 carbon atoms.
