  • Patent number: 6905520
    Abstract: According to the invention, a metal salt and an oxygen source are applied to penetrate or impregnate a suitable substrate sequentially in effective amounts so as to react in contact with the substrate and produce a mineral compound fixed within the surface of the substrate. The inventive combination of a mutually compatible metal salt, oxygen source, and substrate brings about an in situ reaction, and modifies the substrate to bring about a lasting desired effect. The mineral compound that is produced according to the invention is linked to the substrate, is stable and long-lasting or permanent, and is immobilized or insolubilized in the substrate. The mineral compound is bound or contained within and on the surface of the substrate, so it may be said to be ingrained in the fibers or matrix of the substrate, or embedded within the substrate. The desired effect is preferably a color. A wide variety of metal salts may be used depending on the desired effect.

  • Patent number: 6136044
    Abstract: Micro-particles of transition metals or their compounds can be generated as an integral part of a fiber by first attaching a nucleating agent to the fiber, and then adding a solution of metal ions. The ions are reduced by the nucleating agent in the fiber, and micro-particles are generated in or on the fiber. Because of the strong color signal resulting from a low concentration of metal micro-particles, the method is cost effective even when using gold or titanium ions. Various colors were generated by changing the size and spacing of the micro-particles, the metal or metal complex used, and the characteristics of the fiber. The dyed fibers displayed colors ranging from pink, red, purple, yellow, orange, peach, brown, gold, silver, grey, green, and black. These colors resisted bleaching by either chemicals or light.

  • Patent number: 4765797
    Abstract: Liquid formulations of mixtures of cationic dyes frequently have a very short storage life. As a consequence, these formulations give rise to customer complaints concerning incorrect dyeing strengths and hues and concerning isoluble constituents. It has now been found according to the invention that powder formulations and in particular liquid formulations of cationic dyes or of mixtures of these dyes can be stabilized by adding selected oxidizing agents.

  • Patent number: 4752297
    Abstract: A process for coloring wood whereby the resulting color will not change or substantially fade upon exposure to long term environmental weathering, which process comprises contacting the wood with an aqueous solution containing 0.01%-10% of an iron salt derived from a mono-, di-, or tri-carboxylic acid or a mono-, di-, or tri-carboxylic hydroxy acid containing 1-6 carbon atoms. The iron salt solution of this invention may be used to color nontreated wood as well as wood treated with known preservative compositions containing one or more heavy metals including copper, chromium, arsenic and zinc.

  • Patent number: 4655785
    Abstract: A process for the photochemical stabilization of undyed and dyed polyamide or polyurethane fibre material that is characterized in that the fibre material is treated with a water soluble, organic copper, manganese or nickel complex that displays an affinity for the fibres. The polyamide or polyurethane fibre material, e.g., textile, that has been so treated retains its stretch characteristics and elasticity even after prolonged periods of illumination. In addition, in the case of dyed material, treatment with the metal complex results in a marked improvement in light-fastness.

  • Patent number: 4655787
    Abstract: A process for the deposition of a film of an electrophoretic resin upon the surface of a substrate which comprises the steps of(i) electrophoretically depositing from a bath comprising water, a water miscible organic solvent and the resin, a film of the resin upon the surface of the substrate(ii) immersing said film in a solution of a solvent dye in a solvent medium comprising water, a water miscible organic solvent and a hydrotrope, the amount of said solvent dye dissolved in said solvent medium being sufficient for the absorption into the resin film of sufficient dye to impart the desired coloration to the resin film, the amount of said hydrotrope and said solvent being sufficient so that said amount of such solvent dye will dissolve in the solvent medium and(iii) curing the resin.
