    摘要: Polypropylene wax having a) a dropping or softening point determined by the ring/ball method of greater than 155° C., b) heats of fusion greater than 80 J/g and c) a DSC melting point of >155° C. The waxes of the invention are prepared by reaction of propylene with metallocene compounds at temperatures in the range from 40 to 140° C. and an olefin partial pressure in the range from 1 to 50 bar in the presence of a cocatalyst. They have a content of unsaturated chain ends of less than 10%. They can, for example, be modified by means of a free-radical grafting reaction with polar monomers and are, for example, suitable in unmodified form as dispersants for pigments, as additive in printing inks and surface coatings or toners or in modified form for producing aqueous dispersions or as bonding agents and compatibilizers in plastic compounds.

Pigment Blue 15:6, containing 0.5% to 15% by weight of an additive of the formula (1), based on the weight of the pigment, in which R1, R2, R3, R4, R5 and R6 independently of one another are hydrogen; C1-C22 alkyl or C2-C22 alkenyl, whose carbon chain in each case may be interrupted by one or more moieties —O—, —S—, NR9—, —CO— or —SO2— and/or may be substituted one or more times by hydroxyl, halogen, aryl, heteroaryl, C1-C4 alkoxy and/or acetyl; C3-C8 cycloalkyl, whose carbon framework may be interrupted by one or more moieties —O—, —S—, —NR10—, —CO— or —SO2— and/or may be substituted one or more times by hydroxyl, halogen, aryl, heteroaryl, C1-C4 alkoxy and/or acetyl; dehydroabietyl or aryl or heteroaryl, with R9 and R10 independently of one another being hydrogen or C1-C22 alkyl. The pigment composition of the invention is produced with application of a wet grinding process, more particularly a salt kneading operation.
