Method for making a solvent-containing coating material comprising 5 to 70% by weight of at least one mixture of substances (A). The mixture of substances is obtained by copolymerizing in at least one hydroxy-group containing reactive diluent a mixture (A1) of olefinically unsaturated monomers that contain a1) 1 to 90% by weight, based on mixture (A1), of at least one cycloaliphatic monomer and a2) 0 to 90% by weight, based on mixture (A1), of at least one hydroxy-group containing monomer. The coating material further contains 5 to 70% by weight of at least one hydroxy-group containing polyaddition resin (polyadduct) (B) with a Mof 800 to 3,500 and 5 to 70% by weight of at least one cross-linking agent (C) for thermally cross-linking the material. The weight of A, B, and C are based on the solid content of the coating material.

Solvent-containing coating material and the use thereof

The invention relates to a method of producing color pastes, in which a component comprising colorant particles is dispersed in a binder. In the method of the invention the dispersing operation is controlled by beaming excitational light of a defined wavelength range into a mixture of the component comprising colorant particles and the binder, detecting the light transmitted, reflected and/or scattered by the mixture and determining a sample spectrum, evaluating the sample spectrum and hence determining parameters of the color paste, and monitoring changes in the sample spectrum over time and terminating the dispersing operation when predetermined target parameters are attained.

Method for the production of dyestuff pastes

Use of associative thickeners based on polyurethane and/or dipropylene glycol monoalkyl ethers for suppressing defects in color and/or effect multicoat paint systems, or their touch-up paints.
