Abstract: The present invention is drawn to polymer-encapsulated pigments and methods of making the same. The method includes providing an emulsion including water and a discontinuous coating phase having a copolymer dissolved in a monomer mix; providing a pigment dispersion including water, surfactant, and pigments dispersed therein; mixing the emulsion with the pigment dispersion under high shear conditions such that the coating phase is deposited on the pigments, thereby forming polymer and monomer coated pigments; and polymerizing the monomers at the surface of the polymer and monomer coated pigments to form polymer-encapsulated pigments dispersed in a fluid medium.

Abstract: A particle composite including carrier particles having an average diameter of less than 5 ?m. The particle composite is surrounded by a layer made of oxidic material having an irregular surface. Particles, which are made of an active material and which have an average diameter of less than 1 ?m are applied to the layer. The particle composite can be used as a filling substance in polymers and enables the content of active material for comparable properties to be reduced or improves the properties of filled materials, e.g. resistance to aging of elastomers.

Abstract: A general, reproducible, and simple synthetic method that employs readily available chemicals permits control of the size, shape, and size distribution of metal oxide nanocrystals. The synthesis entails reacting a metal fatty acid salt, the corresponding fatty acid, and a hydrocarbon solvent, with the reaction product being pyrolyzed to the metal oxide. Nearly monodisperse oxide nanocrystals of Fe3O4, Cr2O3, MnO, Co3O4, NiO, ZnO, SnO2, and In2O3, in a large size range (3-50 nm), are described. Size and shape control of the nanocrystals is achieved by varying the reactivity and concentration of the precursors.

Abstract: A resin composition that excels in antibacterial action and realizes high aestheticity and safety, these properties retained for a prolonged period of time; and a relevant furniture, electrical household appliance and molding. Coating layer is superimposed on the surface of top board of table (furniture). This coating layer is formed by mixing synthetic resin with glitter and thereafter applying the mixture onto substrate of paper or wood, followed by drying. The glitter is produced by, for example, a process comprising forming a metal layer on a synthetic resin film through vapor deposition of an ion-exchangeable metal, subsequently bonding, with an adhesive, metal-clad synthetic resin films so that the metal layers come inside so as to obtain a sandwich structure and thereafter cutting the sandwich structure linearly or zigzag lengthwise and crosswise.
