Abstract: The present invention provides a process of preparing stained particulates of glass, partially crystalline glass or glass-like amorphous inorganic materials, the process comprising staining particulates of glass, partially crystalline glass or glass-like amorphous inorganic materials that have no dimension greater than 2000 ?m.

Abstract: The invention relates to a process of preparing flakes, the process comprising the steps of: (i) applying a masking agent to a portion of a collecting substrate to provide a masked portion and an unmasked portion of the collecting substrate; (ii) applying a flake precursor to the unmasked portion of the collecting substrate to provide a plurality of flakes attached to the collecting substrate; and (iii) recovering the flakes. The invention also relates to: flakes obtained by said process; a pigment comprising said flakes; a surface coating comprising said flakes; and a use of said flakes as a pigment.

Abstract: The present invention provides a process of preparing particulate products, the process comprising the steps of: (i) subjecting a precursor film to a non-mechanical particulate-defining treatment; and (ii) separating the particulate portion and the non-particulate portion of the film.

Abstract: A phthalocyanine pigment composition comprising a phthalocyanine pigment and a sulphonated phthalocyanine derivative formed from sulphonated phthalocyanine dyestuffs having the formula: ##STR1## AND A SUFFICIENT QUANTITY OF DEHYDROABIETYLAMINE HAVING THE FORMULA ##STR2## to substantially neutralize the free sulphonic acid groups, wherein R represents a C.sub.1 -C.sub.22 cyclic or acyclic alkyl group, aryl, aralkyl group or a dehydroabietylamine residue; and R.sub.1 represents hydrogen or a C.sub.1 -C.sub.22 cyclic or acyclic alkyl group, an aryl or an aralkyl group; the alkyl, cycloalkyl, aryl or aralkyl groups, R and R.sub.1 may be optionally substituted with one or more hydroxyl groups; x is from 1 to 4, y is 0 or from 1 to 3 and the sum of x + y is from 1 to 4 gives printing inks and paint media having improved tinctorial strength, gloss and especially improved rheological properties.

Abstract: The invention relates to a continuous flow process for the preparation of graft copolymers, for example ABS, wherein a mixture of a polybutadiene and/or styrenebutadiene copolymer latex, one or more vinyl aromatic monomers and one or more unsaturated nitrile monomers is continuously supplied to a first stage, graft polymerization is initiated in said first stage, the mixture is continuously removed from the said first stage and supplied to at least a second stage wherein graft polymerization is continued, the temperature in each stage being 50.degree. to 100.degree. C, the conversion of monomers to polymer in the first stage not exceeding 65% by weight, and the overall conversion being at least 80% by weight.
