    Abstract: Dyestuffs of the formulae D-Z - O-OC - X - OyH)n AND D-Z - O-OC - X - OyCOT)n WHEREIN D is the radical of copper phthalocyanine which is attached to Z through a carbon atom of an aromatic ring present in D; Z is a divalent bridging group; n is a positive integer having a value of from 1 to 8 inclusive; X is a divalent saturated or unsaturated aliphatic radical containing at least eight carbon atoms and in which there are at least four carbon atoms between the -CO- and -0- groups; T is a saturated or unsaturated aliphatic radical of from 8-20 carbon atoms and y is a positive number in the range 2-20 inclusive. A process for making the above dyestuffs and their use as dispersing agents in the stabilisation of dispersions of finely divided solids.

    Abstract: Phthalocyanines, halogenomethylphthalocyanines and aliphatic primary or secondary amines are milled together in presence of solid grinding acids which are soluble in, and subsequently removed by, aqueous media. Reaction of the amines and halogenomethylphthalocyanines takes place and pigment compositions are obtained which are readily dispersible in organic solvents and which are of value in inks and paints.
