  • Liquid crystal pigment, method of producing and use in coatings
    Patent number: 5242617
    Abstract: The present invention relates to a liquid crystal pigment which allows the simpler use of liquid crystals in coating applications with greatly improved appearance uniformity of the liquid crystal effect. The liquid crystal pigment comprises a laminar particle which is at least partially coated with a liquid crystalline material, which has been precipitated from a solution onto the laminar particle.

  • Thermochromic effect coating
    Patent number: 5194183
    Abstract: A thermochromic effect coating is provided which that it comprises an aqueous binder component including a flop effect pigment and an encapsulated thermochromic liquid crystal pigment. The particular combination in accordance with the present invention results in a coating with altered flop effect from the flop effect pigment as well as a more uniform color appearance from the liquid crystal pigment.

  • Waterborne coatings and binder systems for use therein
    Patent number: 5098947
    Abstract: A binder system is provided which is suitable for use as a waterborne coating, particularly as a topcoat over hydro-basecoats. The binder in accordance with the present invention comprises a water-soluble acrylic resin which has been modified using a monoisocyanate functional compound. The waterborne coating comprises this binder system in an aqueous base. The resulting waterborne coating exhibits high gloss, high solids content with low cosolvent content, good application characteristics, and good stone-chip and weathering resistance. The present waterborne coating also finds use, for example, as an electrocoat, primer/surfacer and/or solid color topcoat.

  • Aqueous coating composition based on a cationic amino urea resin, process for applying and baking the composition and the coated substrate thus obtained
    Patent number: 4536525
    Abstract: The invention provides an aqueous coating composition based on a cationic amino urea resin having an amine number of 3-250 and obtained by reacting an organic isocyanate with a polyamino amide having an amine number of 40-500 and built up from a mono- or dicarboxylic acid and a polyamine, said composition also containing a solid particulate epoxy group-containing compound and/or a solid particulate polyester having a melting point of at least 40.degree. C. The invention also pertains to the process for applying and baking said composition and to the coated substrate thus obtained.
