Embodiment 1

[0125] 20 parts C.I. Pigment Violet 23 (Component A)

[0126] 11 parts Component (B), formula (1), wherein R 1 and R 7 = Methyl, R 2 and R 6 = Ethylene, R 3 and R 5 =1,4-phenylene, R 4 = 1,2-propylene, a, b, and d add up to an average of about 35, and c averages about 2

[0127] 10 parts of α-methyl-ω-hydroxypolyethylene glycol ether (Mn 470-530g / mol) (component D)

[0128] 8 parts Alkoxylated addition compound of bisphenol A and amine, nonionic (component C)

[0129] 0.2 part preservative (component D)

[0130] Balance Water (Component E).

[0131] The pigment preparations have high tinctorial strength and are stable against flocculation. It can be incorporated very well into all eight white dispersions with easy distribution. The rubbed dispersion test showed no difference in tinting strength in the six cases A, C, D, F, G and H compared to the subsequent rubbed area. In the case of the white dispersions B and E, slight color differences were shown in the rubbing...

Embodiment 2

[0133] 40 parts C.I. Pigment Black 7 (Component A)

[0134] 8.5 parts Component (B), formula (1), wherein R 1 and R 7 = Methyl, R 2 and R 6 = Ethylene, R 3 and R 5 =1,4-phenylene, R 4 = 1,2-propylene, a, b, and d add up to an average of about 90, and c averages about 5

[0135] 10 parts of α-methyl-ω-hydroxypolyethylene glycol ether (Mn 470-530g / mol) (component D)

[0136] 2 parts Alkoxylated addition compound of bisphenol A and amine, nonionic (component C)

[0137] 0.5 parts Di-2-ethylhexyl sodium sulfosuccinate (component C)

[0138] 0.9 part preservative (component D)

[0139] Balance Water (Component E).

[0140]The pigment preparations have high tinctorial strength and are particularly stable against flocculation. It can be incorporated very well into all eight white dispersions with easy distribution. Rubbing dispersion tests showed no difference in tinting strength in all cases compared to subsequent rubbed areas. Of the eight white dispersions, the formul...

[0157] The pigment preparations have high tinctorial strength and are particularly stable against flocculation. It can be incorporated very well into all eight white dispersions and white varnish A with easy distribution. Rubbing dispersion tests showed no difference in tinting strength in all cases compared to subsequent rubbed areas. The formulation was "generally compatible" in the coating systems tested. The pigment preparation has good rheological properties and has prov...

Abstract

The invention relates to an aqueous pigment preparation containing: (A) at least one organic and / or inorganic pigment; (B) at least one water-soluble or water-dispersible non-ionic oligoester or polyester, which is obtained by the polycondensation of dicarboxylic acid and glycol components, said oligoester or polyester comprising: I) one or more aromatic dicarboxylic acids, their esters or anhydrides, II) C2-C8 alkenediols, III) poly(C1-C4-alkene)glycols and / or methylpoly(C2-C4 alkene)glycols, IV) optional water-soluble addition products of alkene oxide on C1-C24 alcohols, C6-C18 alkylphenols or water-soluble adduction products on C8-C24 alkylamine, and V) optional one or more polyalcohol; (C) optional alternative dispersent used for preparing aqueous pigment dispersing medium in convention and surfactant; (D) optional alternative adjuvant used for preparing aqueous pigment dispersing medium in convention; and (E) water.

Description

technical field [0001] The present invention relates to aqueous pigment preparations or dispersions based on oligoesters, to a process for their preparation and to their use for coloring natural and synthetic materials, especially all types of aqueous paints, latex paints and colored paints (Lackfarben) . Background technique [0002] For coloring in the applications mentioned above, it is very common today to use aqueous pigment preparations. Such formulations are described, for example, in EP0735109, WO03 / 006556 or EP1049745. Dispersants are used in the preparation of these formulations, which physically stabilize the pigment particles in finely divided form in aqueous media. Anionic, cationic, amphoteric or nonionic dispersants having surfactant character, where appropriate also in macromolecular form, are generally used. The most frequently used dispersants include alkaryl compounds, their alkoxylated (Oxalkylierung) products and sulfonated or phosphated products, add...
