Patent number: 6980292Abstract: 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.Type: GrantFiled: November 22, 2002Date of Patent: December 27, 2005Assignee: BASF Coatings AGInventors: Claudia Sierakowski, Ines Mangels, Zenon-Paul Czornij, Thomas Krüger, Peter Hoffmann, Thomas Frey, Benno Sens, Manfred Mielke, Paul Günthert, Gerhard Berger, Peter Blaschka, Günter Etzrodt

Publication number: 20030092833Abstract: A pigment paste for use in preparing aqueous paints includes a binder that includes at least one polyurethane acrylate resin, water as a solvent, and a pigment component that may be an organic pigment, an inorganic pigment, or carbon black. Preferably, the polyurethane acrylate is a product of a process comprising polymerizing one or more ethylenically unsaturated monomers in the presence of a polyurethane resin, which has a number-average molecular weight from about 200 to about 30,000, and which contains, on average, from about 0.05 to about 1.1 polymerizable double bonds per molecule. The reaction product is then converted into an aqueous dispersion, and mixed with the pigment and water to form the pigment paste. A preferred pigment paste contains from 10 to 35% of the polyurethane acrylate resin, from 10 to 65% water, and a percentage of the pigment component which varies, depending on the material selected.Type: ApplicationFiled: November 1, 2002Publication date: May 15, 2003Inventors: Joachim Frieling, Andreas Kraemer, Peter Mayenfels, Claudia Sierakowski, Berhard Lettmann
