Abstract:
The invention relates to a method for producing the quaterrylene-3,4:13,14-tetracarboxy diimides of general formula (I), wherein R, R' independently represent hydrogen or optionally substituted C 1 -C 30 alkyl, C 3 -C 8 cycloalkyl or aryl or hetaryl. The inventive method is characterized by reacting the perylene-3,4-dicarboximide of the general formula (IIa) in the presence of a base resistant, high-boiling, organic solvent and an alkali-containing or alkaline earth-containing base with the perylene-3,4-dicarboximide of the general formula (IIb), wherein X represents hydrogen, bromine or chlorine.
Abstract:
Automatically producing and characterizing a liquid system comprising at least two components comprises automatically producing a mixture by combining at least two components in a vessel, at least one component being automatically dosed into the vessel; automatically homogenizing the mixture obtained to form the multi-component system; and automatically evaluating. An Independent claim is also included a device for automatically producing and characterizing a liquid system comprising at least two components comprising a dosing station (5), a closing station (7), a homogenizing station (9), a measuring station (13) for determining formulation properties, and an evaluation unit. Preferred Features: The multi-component system contains at least three components.
Abstract:
The invention relates to a method for carrying out the automated preparation and characterization of liquid multi-constituent systems comprised of at least two, preferably at least three, constituents. The inventive method involves the automated preparation of a mixture by combining at least two, preferably at least three, constituents in a vessel, whereby at least one constituent is dosed into the vessel in an automated manner. The method also involves the automated homogenization of the mixture followed by an automated measuring and evaluation. The device for implementing said method comprises at least one dosing station (5), a closing station (7), a homogenizing station (9), a measuring station (13) for determining formulation properties, and an evaluation unit.

Abstract:
Pigment formulations in granule form, comprising a pigment (A), at least one thermoplastic polymer (B), and if desired a dispersant (C), obtainable by a) dispersing the pigment (A) in a solution of the polymer (B) in an organic solvent in the presence or absence of a dispersant (C), and b) subsequent formation of granules with removal of the solvent.
Abstract:
A pigment formulation in granule form obtainable by a) dispersing at least two different pigments (A) in a solution of a thermoplastic polymer (B) in an organic solvent in the presence or absence of a dispersant (C), and b) applying as a layer the dispersion produced in step a) to granules of a thermoplastic polymer (B'), which is the same as the polymer (B), with removal of the solvent, wherein the pigment formulation includes the granules of the thermoplastic polymer (B'); and a coating on the granules of the thermoplastic polymer (B'), where the coating comprises the at least two different pigments (A) and the thermoplastic polymer (B).
Abstract:
Preparation of granulated pigment comprises: (1) dispersing at least two different pigments in a solution of a thermoplastic polymer(s) and optionally a dispersing agent; and (2) granulating the mixture with solvent removal. Independent claims are also included for the following: (1) plastic molding compositions colored with the pigment preparations; and (2) laminated films containing at least one layer colored with the pigment preparation.
