Abstract

Prepn. of pigment compsns. in bead form, comprises mixing (A) 1 pt. insoluble organic carrier melting at 100 degrees C, with an aq. dispersion contg. (B) 0.25-2.3 pts. pigment or water-insoluble dye, in presence of (C) a protective colloid, at a temp. above the m. pt. of (A), until (B) has combined with (A), and the aq. phase is virtually free of (B). The beads obtd. are then isolated. The pigments are used in the colouring of inks, paints and plastics. Good yields of well-formed; free-flowing beads are obtd., which are non-dusting and easily incorporated to give uniformly coloured products.
