  • Patent number: 11944997
    Abstract: A surface decoration structure includes an undercoat film, a silver mirror film layer, and a topcoat film formed on a surface of a substrate. The silver mirror film layer includes a film of stacked nanometer-sized silver particles having surfaces coated with a polymer dispersing agent, and the topcoat film includes, as a solvent, at least one member selected from the group consisting of an aliphatic hydrocarbon compound, an aliphatic hydrocarbon compound solution including 10% by mass or less of an aromatic compound, and diisobutyl ketone. The undercoat film and/or the topcoat film may include a corrosion inhibitor. The silver mirror film layer may further include a corrosion inhibitor. The surface decoration structure includes the silver mirror film layer with improved luster and corrosion resistance.
    Type: Grant

  • Patent number: 9856396
    Abstract: A surface ornament composition for fishing tackle or a bicycle is provided. An inner coating layer is laminated on a part made of fiber reinforced plastics, a silver thin film coating layer is laminated on the inner coating layer and an outer coating layer is laminated on the silver thin film coating layer. The inner and outer coating layers are formed by use of one selected from resin paint of two-part type formed by urethane reaction of isocyanate group and hydroxyl group, resin paint of two-part type formed by reaction of resin having amino group and silicon compound having epoxy group and resin paint of two-part or three part type in which the above two reactions are simultaneously generated. The silver thin film coating layer is formed of metal complex of silver with amine as ligand that is heated after having been applied.

  • Patent number: 6835772
    Abstract: This invention aims to provide a favorable feel coating film having gently soft feel (comfortable feel), a coating composition for forming the coating film, and fine particles of a polymer for incorporation in the coating composition, and concerns with fine particles of lanolin-deposited polyurethane resin obtainable by reacting at least one of polyesters and polyethers with polyisocyanate having at least two isocyanate groups in a poor solvent in the presence of a lanolin derivative; a coating composition comprising (i) at least one binder resin selected from the group consisting of polyester resins and polyether resins, the binder resin having a specific glass transition temperature, a specific number average molecular weight and a specific hydroxyl value, (ii) polyisocyanate having at least two isocyanate groups, (iii) the fine particles of polyurethane resin as described above, and (iv) an organic solvent; and an article coated with the coating composition.
