- naphthalene sulfonic acid / formaldehyde condensation products are particularly suitable. Mixtures of these dispersants can also be used.
- Individuals of the ethylene oxide units can be replaced by other epoxides, e.g. Styrene oxide or, in particular, propylene oxide.
- Mixtures of the ethylene oxide adducts according to a) to f) with one another can also be used. These mixtures are obtained by mixing individual reaction products or directly by ethoxylating a mixture of the compounds on which the adducts are based. An ethoxylated nonylphenol is preferably used.
- Quaternary fatty amine polyglycol ethers are suitable as cationic dispersants.
- the preparation can also contain 45-95% water, preservatives and defoamers. However, the solid preparations are preferred.
- the preparations according to the invention are prepared by simply mixing or dry grinding the components or by melting the dispersion brightener and the auxiliary, if appropriate in the presence of dispersants and / or emulsifiers, allowing them to solidify and then, if appropriate, dry-grinding or, if appropriate, wet-grinding in the presence of dispersants and / or emulsifiers will.
- the preparations according to the invention are suitable for lightening the coating slips usually used in the paper industry, specifically for lightening unpigmented, but in particular pigmented coating slips.
- These known coating slips contain, inter alia, binders.
- a preferred binder consists of styrene-butyl acrylate or styrene-butadiene-acrylic acid mixed polymers. Further polymer latices are described, for example, in US Pat. Nos. 3,265,654, 3,657,174, 3,547,899 and 3,240,740. The preparation according to the invention is incorporated into these binders, for example by means of melt emulsification.
- Aluminum silicates such as china clay and kaolin, barium sulfate, satin white, titanium dioxide or calcium carbonate (chalk) are usually used to pigment the coating slips.
- the coating slips according to the invention preferably contain 30 to 70% of a white pigment.
- the binder is preferably used in an amount sufficient that the dry content of polymeric compound is 1 to 30 percent by weight, preferably 5 to 25 percent by weight, of the white pigment.
- the amount of the brightener preparation according to the invention is calculated in such a way that the dispersion brightener is present in amounts of 0.001 to 1 percent by weight, in particular 0.01 to 0.55 percent by weight, based on the white pigment.
- the coating slip according to the invention can be produced by mixing the components in any order at temperatures from 10 to 100 ° C., preferably 20 to 80 ° C.
- the components here also include the usual auxiliaries that can be used to regulate the rheological properties such as viscosity or water retention of the coating slips.

Use on paper and cardboard and photo paper is particularly preferred.
- the coating slip can be applied to the substrate by any conventional method, for example using an air knife, a doctor knife, a brush, a roller, a squeegee or a stick, followed by coating with, for example, infrared dryers and / or hot air dryers at paper surface temperatures in the range of 70 up to 200 ° C, preferably 90 to 130 ° C, to a residual moisture content of 3-6%. Comparably high degrees of whiteness are thus achieved even at low drying temperatures.
- the coatings obtained are distinguished by an optimal distribution of the dispersion brighteners over the entire surface and a consequent increase in the white level as well as a high light fastness.
- the brightener of the formula is ground with the parts of the components listed in Table 1 at room temperature for 15 hours in a glass bead mixer (glass bead diameter 2 mm) in the presence of water.
- the brightener according to Example 1 is melted together with the components and parts shown in Table 2, dry-ground after cooling and then dispersed according to Example 1 in water.
- 700 g of a commercially available kaolin pigment and 300 g of a commercially available calcium carbonate pigment are dispersed with 385 g of water, 5 g of a dispersant based on sodium salt of a polycarboxylic acid at a pH of about 9 and under the action of strong shear forces.

- the brightener is used at 0.3%, based on the amount of pigment used.
- the coating color is then adjusted to a solids content of 50% by dilution with water.
- the line is applied to wood-free coating paper which has been acid-glued according to the usual methods with the help of a hand knife, so that the line weight after drying with the help of an IR radiator is approx. 15 g per m2. The residual moisture still present after this drying is approx. 2%.
- the whiteness of the coating is determined according to "Ciba-Geigy whiteness", as described in "Status of the instrumental whiteness assessment with special consideration of the lighting", textile finishing 5/1983, p.
- the degree of whiteness of the preparations 1.1 to 2.7 is given in Table 3.
- a coating slip without additive, but with 0.3% of the brightener according to Example 1 and the dispersants mentioned in Table 4 is prepared and applied analogously to the procedure used in Example 3 (preparations 4.1 to 4.4). The results of the whiteness measurement are compared in Table 4 to those corresponding preparations from Example 2.
- the coating color thus obtained is adjusted to a solids content of 50% by dilution with water, applied in accordance with Example 3b) and the degree of whiteness is determined in accordance with Example 3c).
- the degrees of whiteness are shown in Table 5.
