Patent number: 8535391Abstract: The present invention is concerned with a dye system for application to a substrate, the dye system comprising: (a) at least one dye precursor; (b) an oxidizing agent; and (c) a catalyst, wherein the catalyst is a homogeneous catalyst or a heterogeneous catalyst. Preferably, the catalyst comprises at least one metal-containing compound. The invention also envisages a method for the coloration of a substrate, the method comprising treating the substrate with the dye system of the invention. In preferred embodiments of the invention, the substrate comprises human hair, natural or synthetic polymers, or textile fibers. In further preferred embodiments, the at least one dye precursor is an organic precursor, the at least one metal derivative for use as a catalyst comprises at least one inorganic metal compound or at least one metal complex comprising at least one organic ligand, and the oxidizing agent is hydrogen peroxide.Type: GrantFiled: June 30, 2010Date of Patent: September 17, 2013Assignee: University of LeedsInventors: Richard Simon Blackburn, Patrick Columba McGowan, Christopher Martin Pask, Christopher Mark Rayner

Patent number: 8361167Abstract: The invention provides dye mixtures for application to human hair, the dye mixtures comprising polyphenolic materials, these materials being obtained from botanical sources. Preferably, the botanical source is fruit, especially fruit selected from blackcurrants, blackberries, blueberries, bilberries, cranberries, grapes, chokeberries, Saskatoon berries, sea-buckthorn, mulberries acai, cherries, red cabbage and/or figs. Preferably, the polyphenolic materials comprise anthocyanin compounds which, most preferably, are aglycone anthocyanidins or glycosylated anthocyanins of the formula (III): wherein R1 and R2 are, independently, H, OH or OCH3, R3 is OH (aglycone anthocyanidins) or a glycosyl group (glycosylated anthocyanins), and x is a counter-ion. The invention also provides methods for the preparation of these dye mixtures and for the use of the dye mixtures in the semi-permanent coloration of human hair.Type: GrantFiled: May 14, 2010Date of Patent: January 29, 2013Assignee: University of LeedsInventors: Richard Simon Blackburn, Paul Martin Rose, Christopher Mark Rayner

Publication number: 20090227762Abstract: The present invention provides a catalyst for use in the preparation of a coloured polymeric material, said catalyst comprising a coloured organometallic compound. Preferably, said catalyst comprises a metal such as aluminium and at least one organic chromophore, such as an azo chromophore, said chromophore being either directly bonded to said metal, or indirectly bonded to said metal through a ligand. The invention also envisages a method for the preparation of a coloured polymer, the method comprising performing a polymerisation reaction in the presence of such a catalyst. The method is particularly applicable to the preparation of poly(lactic acid), and offers significant benefits over the processes of the prior art, both economically and environmentally.Type: ApplicationFiled: October 31, 2006Publication date: September 10, 2009Applicant: UNIVERSITY OF LEEDSInventors: Richard Simon Blackburn, Christopher Mark Rayner, Christopher Martin Pask, Patrick Columba McGowan
