The influence of mixed coupling on the properties of C.I. Pigment Yell
ow 12 is studied. Carboxy and sulfo derivatives of acetoacetanilide we
re used as the second modifying coupling components. The results showe
d that the state of the crystal and particle size changed; the pigment
flowability, and dispersibility in non-polar solvents decreased die t
o the introduction of polar groups. (C) 1998 Elsevier Science Ltd. All
