preparation Embodiment 1

[0100]25 g of bentonite (pH 7-12) were dispersed in 500 ml of deionized water by stirring at 20° C. for 12 hours. The suspension was then adjusted to a pH value of 4-10 by dilute sulfuric acid and thereafter 10 g of a 77% aqueous solution of distearyl dimethyl ammonium chloride (DSDMAC) was added to the bentonite suspension, and the reaction mixture was heated at 60° C. Stir for 1 hour. After a reaction time of 1 hour, a mixture of 7 g of a 77% strength aqueous solution of DSDMAC and 50 g of a 10% strength aqueous montanic ester wax dispersion prepared by adding 10 g of molten montanic ester wax ((R) Licowax F, Clariant Company, acid Value 6-10mg KOH / g, drop point 75-81 ℃) add about 95 ℃ hot water solution preparation, this hot water solution is prepared by 0.7g 21% concentration KOH-ethylene glycol solution, 3g 10% concentration polyvinyl alcohol solution (( ) Mowiol 4-88, Kuraray Company, Germany) and 86.3g deionized water.

[0113] 25 g of bentonite (pH 7-12) were dispersed in 500 ml of deionized water by stirring at 20° C. for 12 hours. The suspension was then adjusted to a pH value of 4-10 by dilute sulfuric acid and thereafter 17 g of 77% strength distearyl dimethyl ammonium chloride aqueous solution (DSDMAC) was added in two portions to the bentonite suspension, and the reaction mixture Stir at 80°C for 1 hour. After a reaction time of 1 hour, 50 g of a 10% strength isopropanol wax solution comprising a wax mixture of 75% erucamide wax and 25% carnauba wax were added. The reaction mixture was stirred at 80° C. for a further 1 hour, and the solid was filtered off with suction, post-washed several times with deionized water and then dried at 60° C. in vacuo.

Abstract

A salt-like, hydrophobic structured silicate is disclosed. The cation of the salt-like structured silicate is a low-molecular organic cation or a combination thereof with an NH4<+>, H3O<+>, alkali metal, alkaline earth metal, earth metal and/or transition metal ion. The anion of the salt-like structured silicate is an island, ring, group, chain, band, layer or tectosilicate, or a combination thereof. The structured silicate is produced by (a) reacting a structured silicate whose cation is an NH4<+>, H3O<+>, alkali metal, alkaline earth metal, earth metal and/or transition metal ion or a combination thereof, and whose ion is an island, ring, group, chain, band, layer or tectosilicate, or a combination thereof, in an aqueous dispersion with a low-molecular organic cation; by (b) adding to and intensively blending with the aqueous structured silicate dispersion a hydrophobic compound from the group of waxes and metal soaps, in a quantity ranging from 0.2 to 200 % by weight of the salt-like structured silicate in step (a), before, during and/or after step (a) is carried out; and by (c) optionally removing, drying and isolating in the form of a powder the salt-like, hydrophobic structured silicate produced during step (b).

Description

technical field [0001] The present invention relates to the field of charge control agents in the sense of selectively influencing components with electrostatic charging properties in a matrix. Background technique [0002] In the electrophotographic recording process, a "potential image" is produced on a photoconductor. This "latent image" is developed by the application of electrostatically charged toner, which is then transferred, for example, to paper, textile, film or plastic, and fixed, for example by means of pressure, radiation, heat or the action of solvents. Typical toners are one-component or two-component powder toners (also known as one-component or two-component developers), and additionally specialty toners such as magnetic toners, liquid toners toner or polymerized toner. By "polymerized toner" is meant, for example, those toners formed by suspension polymerization (condensation) or emulsion polymerization and resulting in improved particle properties of th...
