Patent number: 6022619Abstract: A colored textile composite is produced by forming an iron (III) oxide film on a textile surface. This is accomplished by contacting the textile with an aqueous solution having an iron (II) or iron (III) species present. The iron (II) ion resulting from the dissociated iron (II) salt, if an iron (II) salt is utilized, is first hydrolyzed within the aqueous solution and then oxidized under controlled conditions to form iron (III) oxide (hydroxide). The iron (III) ion resulting from the dissociated iron (III) salt, if an iron (III) salt is utilized, is only hydrolyzed under controlled condition to form iron (III) oxide (hydroxide). The iron (III) oxide is then nucleated and forms a smooth and coherent iron (III) oxide film or coating on the surface of the textile without forming an insoluble iron (III) hydroxide precipitate in the solution.Type: GrantFiled: January 15, 1998Date of Patent: February 8, 2000Inventor: Hans H. Kuhn

Patent number: 5092907Abstract: The liquid colorant dispersion intended to be incorporated in plastic materials prior to their transformation and intended to color in bulk these plastic materials comprises a vehicle principally comprising a terpene oil based on pinene and colorant materials. An ethoxylated alkylphenol and other surface-active constituents selected from the group comprising sodium dioctylsulfosuccinate, sodium benzoate, fatty acid condensates, phosphoric ester and alkylpolyalkoxylate may be added to the vehicle. This dispersion compatible with conventional polymers permits obtaining products of a homogeneous coloration, without surface alteration and without distortions.Type: GrantFiled: February 22, 1990Date of Patent: March 3, 1992Assignee: Sicpa Holding S.A.Inventors: Jean-Jacques Riblet, Gilles Catherin
