  • Patent number: 5795376
    Abstract: A coated pigment highly surface-modified with a substantially water-insoluble organic surface modifier, produced by preparing a mixture of water and a substantially water-insoluble organic surface modifier, pressurizing the mixture, introducing the mixture into a flow path having a diameter-decreased portion and a turning portion to cause a shear force in the mixture of which the flow is accelerated while the mixture is passing the diameter-decreased portion, mutual collision of the mixture of which the flow has been accelerated or collision of the mixture of which the flow has been accelerated against a wall constituting the flow path, thereby obtaining an aqueous dispersion in which the substantially water-insoluble organic surface modifier is homogeneously dispersed in the water, mixing the aqueous dispersion with the pigment to coat the pigment with the substantially water-insoluble organic surface modifier, and isolating the pigment coated with the substantially-water-insoluble organic surface modifier.

  • Patent number: 5770299
    Abstract: The invention relates to an effect paint for objects to be painted, as well as to a process for making the effect paint, wherein the effect paint comprises pigments. The pigments, produced by fragmenting a wiped and cross-linked film, are added to a starting paint of a paint coat of the object and result in color effect which depends on the viewing angle, and are also provided with a marking used to recognize and characterize the object.
