  • Patent number: 10246561
    Abstract: A method is used to prepare silver nanoparticle cellulosic polymer composites. A cellulosic polymer, reducible silver ions in an amount of a weight ratio to the cellulosic polymer of 5:1 to 50:1, and an organic solvent are mixed. Each organic solvent has a boiling point at atmospheric pressure of 100° C. to 500° C. The Hansen parameter (?TPolymer) of the cellulosic polymer is less than or equal to the Hansen parameter (?TSolvent) of the organic solvent. The resulting premix solution is heated to at least 75° C., and a (d) nitrogenous base is added to provide a concentration of the nitrogenous base in an equimolar amount or in molar excess in relation to the amount of reducible silver ions, thereby forming a silver nanoparticle cellulosic polymer composite. After cooling, the silver nanoparticle cellulosic polymer composite is isolated and re-dispersed in an organic solvent to provide a non-aqueous silver-containing dispersion.

  • 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.
