Abstract

Improvements introduced in the preparation of compositions for color development comprising (1) a primary aromatic amino developer, (2) a color-forming copulator, (3) an alkali, and (4) a water-soluble developer selected of those with the formula: ** (See formula) ** wherein R represents a hydrogen atom or an alcohol group; R 'represents an alkyl group or an aminoalcohyl group, and n is an integer from 1 to 8, such that in compounds having the formula 1, the total number of carbon atoms in the R and R' groups taken together is at least 2 and not more than 8, and such that in the compounds having the formula II, the total number of carbon atoms of the two R groups and in the group - (CH2) n- is at least 2 and not more than 8 (Machine-translation by Google Translate, not legally binding)
