Abstract
Compound of the formula: ##STR1## in which Pc represents a metallized or non-metallized phthalocyanine residue, X represents a hydrogen or alkali metal atom, one of the substituents R.sub.1 and R.sub.2 represents a linear alkyl or alkenyl residue containing 12 to 18 carbon atoms, and the other represents a hydrogen atom, n represents a whole number or a fraction from 0 to 2 inclusive, m represents a whole number or a fraction from 2 to 4 inclusive, and the sum m + n is equal to or greater than 3; mixtures thereof and derivatives resulting from the action of an SO.sub.3 X group on an amino group of a compound of formula (I) or on a compound of the formula: R.sub.1 --hn--ch.sub.2 --ch.sub.2 --ch.sub.2 --r.sub.2 in which X, R.sub.1 and R.sub.2 have the meanings given above. These compounds are useful for the coloration of fats or waxes and may be prepared by reacting one mole of sulphochloride of the formula: ##STR2## WITH AT LEAST M MOLES OF A PROPYLENEDIAMINE OF THE FORMULA: R.sub.1 -- HN -- CH.sub.2 -- CH.sub.2 -- CH.sub.2 -- NH -- R.sub.2 (III) in which Pc, X, n, m, the sum n + m, R.sub.1 and R.sub.2 have the meanings given above.
