    摘要： Crude copper phthalocyanines are transformed into a pigmentary state by treating finely divided but imperfectly crystallized and highly aggregated crude copper phthalocyanines having a primary particle size, produced by ball milling, or less than 0.1 .mu.m with an organic solvent by subjecting a suspension of the organic solvent and the milled crude copper phthalocyanine (hereinafter referred to as the solvent/pigment suspension), which has a pigment concentration of from 15 to 55% by weight and a solvent concentration of from 15 to 85% by weight and which may contain water in a concentration of from 0 to 30% by weight, to a shear gradient of from 1000 to 20000 s.sup.-1 for a period of from 2 to 1000 s with an energy uptake during shearing of from 0.01 to 0.02 kWh/kg of pigment throughput, then metering water into the solvent/pigment suspension in an amount of from 0.1 to 10 times the amount of the solvent, to effect a defined discontinuation of the conditioning process, and finally mixing the suspension until homogeneous.

    摘要： Aqueous non-self-emulsifying polymer dispersions having small particles and a long shelf life and based on highly viscous reaction resins are prepared without the addition of solvents, by means of an intensively dispersing screw apparatus, by a continuous process in which the preparation of the polymer dispersion is carried out in an intensive shear zone of the screw apparatus, the water/reaction resin ratio in this intensive shear zone corresponding to the phase inversion point or being close to it, and the specific energy supply is 0.01-0.15 kWh/kg, the residence time is 0.1-60 sec and the shear gradient is 2,000-20,000 sec.sup.-1.
