Abstract
Abstract Pigment preparations which contain an organic pigment and/or carbon black and a surfactant from the sulphosuccinic acid ester and/or alkylbenzenesulphonate series and which have been dried, if appropriate after wet comminution, by spray- or freeze-drying from an aqueous medium, and the use of these preparations for pigmenting high molecular weight organic material, in particular thermoplastics.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
44 words
Pigment preparations consisting essentially of an organic pigment and/or carbon black and a surfactant selected from the group consisting of sulphosuccinic acid ester series, alkylbenzenesulphonate series and mixtures thereof, which have been dried, after wet comminution, by spray- or freeze-drying from an aqueous medium.
Claim 2
Dependent Claim
44 words
Pigment preparations consisting essentially of an organic pigment and/or carbon black and a surfactant selected from the group consisting of sulphosuccinic acid ester series, alkylbenzenesulphonate series and mixtures thereof, which have been dried, after wet comminution, by spray- or freeze-drying from an aqueous medium.
Claim 3
Dependent Claim
69 words
Pigment preparations according to claim 1 wherein the surfactant is a sulphosuccinic acid ester of the formula ##STR16## in which R and R 1 represent hydrogen or a C 1 -C 24 -hydrocarbon radical, but R and R 1 do not simultaneously denote hydrogen, n designates 1 or 2 and Me, for n=1, represents an ammonium radical or an alkali metal and, for n=2, represents an alkaline earth metal.
Claim 4
Dependent Claim
13 words
Pigment preparations according to claim 1, wherein the surfactant is a bis-(2-ethylhexyl) sulphosuccinate.
Claim 5
Dependent Claim
81 words
Pigment preparations according to claim 1, wherein the surfactant is an alkylbenzenesulphonate of the formula ##STR17## in which R 2 , R 3 and R 4 represent hydrogen or a C 1 -C 24 - alkyl radical, at least one of the substituents R 2 , R 3 and R 4 not being hydrogen and m designates 1 or 2 and M, for n=1, represents hddrogen, an ammonium radial or an alkali metal, and for m=2, represents an alkaline earth metal.
Claim 6
Dependent Claim
12 words
Pigment preparations according to claim 1 wherein the surfactant is a dodecylbenzenesulphonate.
Claim 7
Dependent Claim
31 words
Pigment preparation according to claim 1, wherein the pigment, an azo pigment is an azo pigment lake, a metal complex pigment, an anthraquinoid pigment, a phthalocyanine pigment or a polycyclic pigment.
Claim 8
Dependent Claim
26 words
Pigment preparations according to claim 1, consisting essentially of (I) 80-99% by weight of organic pigment and/or carbon black; and (II) 20-1% by weight of surfactant.
Claim 9
Dependent Claim
20 words
A pigmented high molecular weight material comprising a high molecular weight material and a pigment preparation according to claim 1.
Claim 10
Dependent Claim
19 words
A pigmented high molecular weight material accoding to claim 8 wherein the high molecular weight material is a thermoplastic.
Claim 11
Dependent Claim
26 words
