摘要:
The instant invention relates to a process for the production of colored metallic pigments, as well as these colored metallic pigments themselves, their use to color high molecular weight organic material in the mass and compositions or masterbatches containing them. The colored metallic pigment consists essentially of multiple loose particles of 0.1-1000 µm size each, said particles comprising a core of a transition metals, half metal or alloy, preferably an aluminum flake, and a very fine, substantially continuous, uniform and homogeneous layer of organic pigment particles which is directly in contact with the metallic core. The core may be superficially oxidized. The colored metallic pigment is prepared by a vacuum deposition process, said process being performed in an apparatus constructed, modified or charged in such a way that the organic pigment gas flows in direction of the metallic core.

摘要:
The invention is related to an electrophotographic photoreceptor, its preparation, and its use in electrophotography. The instant photoreceptor comprises a conductive substrate and a photosensitive layer containing an organic pigment as a charge generating material, wherein said organic pigment is formed from a soluble organic pigment precursor. Particularly suitable soluble pigment precursors are of formulae (I) or (XIV),
wherein A represents a chromophore residue which is a perylene, quinacridone, dioxazine, anthraquinone, azo, phthalocyanine, isoindolinone, isoindoline, indigo, quinophthalone or pyrrolopyrrole with 1 to 5 N atoms bound to the D 1 and D 2 groups, whereby each N atom of A is independently from the other bound to 0, 1 or 2 groups D 1 or D 2 ; D 1 and D 2 are independently a group represented by the general formula
x is an integer from 0 to 4; L 1 and L 2 are independently from one other halogen, alkoxy or amino groups, and M 2 is two hydrogens or a metal or oxometal with at least two valences; as well as derivatives thereof. The instant electrophotographic photoreceptors have hight sensitivity and low residual electric potential and can be obtained without applying any dispersion procedure.
