  • Patent number: 8841063
    Abstract: A light source is configured to emit a narrow peak at a discrete spectral band, especially at a primary color wavelength. The light source can have a plurality of narrow peaks to simulate the effect of a broadband light source. A subject is provided with a pigment, such as certain rare earth lanthanides, with a strong absorption peak at a corresponding narrow spectral band. The pigment has a nominal color when illuminated by a true broadband light (e.g., sunlight) that does not have a narrow peak at the discrete spectral band, and has a different color when illuminated by the light source that has a narrow peak. This color shift can be used for security authentication, information and decorative applications.

  • Publication number: 20140261083
    Abstract: A continuous process for making a pigment dispersion includes continuously feeding a pigment into a feed section of a screw extruder at a controlled rate, continuously feeding a surfactant into the feed section of the screw extruder at a controlled rate, continuously feeding water downstream of the feed section to emulsify the pigment and the surfactant, forming a water-in-pigment dispersion, continuously feeding additional water downstream of the previously fed water to cause a phase inversion of the water-in-pigment dispersion, forming a pigment-in-water dispersion, continuously homogenizing the pigment-in-water dispersion in the screw extruder to create a homogenous aqueous pigment dispersion and collecting the homogenous aqueous pigment dispersion from an exit section of the screw extruder.

  • Publication number: 20140275369
    Abstract: The present invention is directed to ready to use (wet) and setting (dry) repair products with antistatic additives having reduced persistent airborne dust particulates upon sanding thereof. Such wet and dry repair products include, in part, an antistatic additive(s) that can reduce or eliminate the static charge that forms in dust particulates when dried repair products, such as spackling compounds, cementitious materials, and joint compounds, are sanded, for example. In turn, this can help reduce the quantity of airborne dust particulates, the time in which they are suspended, and the distance they travel in a given room or job site. In one example, a repair product for use as a dry repair compound can include an anti-static additive, which can include a cationic charge, and optionally a metal complex. In another example, the repair product further includes water to define a wet or ready to use repair product.

  • Patent number: 8778140
    Abstract: A method of preparing a stable dispersion of flocculated filler particles for use in papermaking processes comprises use of microparticle prior to, simultaneous to, and/or after addition of a first flocculating agent to an aqueous dispersion of filler particles, followed by addition of a second flocculating agent to the dispersion and further optional shearing of the resultant filler flocs to the desired particle size resulting in shear resistant filler flocs with a defined and controllable size distribution. In addition, a neutralizing coagulant can be added to the dispersion to partially or completely neutralize the charge of the filler before the microparticle and/or the first flocculating agent is added.

  • Publication number: 20140154520
    Abstract: A process for preparing embossed fine particulate thin metal flakes having high levels of brightness and color intensity. The process comprises forming a release coat on a flexible polymeric carrier film, embossing the release coat with a diffraction grating pattern that is monoruled at an angle above 45°, vacuum metalizing the embossed release surface with a highly reflective metal such as aluminum, and solubilizing the metalized release coat in a solvent for removing the metal from the carrier to form embossed metal flakes that replicate the embossment pattern. The flakes are recovered from the solution containing the solvent and release coat polymer while avoiding high shear, particle sizing or other application of energy that would excessively break up the flakes, so that the D50 particle size of the flakes is maintained at or above 75 microns.
