A method of colouring an eyebrow, the method comprising: (i) contacting the eyebrow with a colouring composition comprising: (a) a dye compound; (b) an organic acid; and (c) an aromatic compound.

Method and composition for colouring an eyebrow comprising an organic acid

A composition comprising a first infrared absorbing material which is a doped metal oxide comprising indium and/or tin; and a second infrared absorbing material which is a compound selected from: or a salt or polymer thereof, wherein &#x2014;M is a metal selected from a group 3-10 (Group 1MB-VIII) element or a lanthanide; &#x2014;Ris selected from hydrogen, phosphonate, sulphonate, nitro, halo, cyano, thiocyano, thioalkyl, thioaryl, alkyl, alkoxy, aryl, aryloxy, amines, substituted amines and substituted aryl; &#x2014;one of Rand Ris oxygen and the other of Rand Ris NO; &#x2014;n is a number corresponding to half the co-ordination number of the metal M; &#x2014;each L and L' is independently a ligand complexed to the metal M; and &#x2014;y is a number corresponding to the co-ordination number of the metal M. 

Security printing

An article comprising a substrate which carries a doped tin oxide wherein less than 50 mol % of the tin atoms in the tin oxide are substituted with a dopant element.

A coloring composition comprising: (i) at least 0.0001 wt % of a water-soluble dye compound containing one or more sulfonate and/or carboxylate groups; (ii) at least 0.1 wt % urea; (iii) from 0.1 to 2.5 wt % of a thiol; (iv) less than 0.5 wt % ammonia; and (v) less than 0.5 wt % sulfite ions.

Hair treatment methods

An image article comprises a substrate having a security image coated on at least a portion thereof, which security image effects less than 50% reflectance of radiation of a wavelength between 800 and 900 nm, wherein the security image comprises a defined infrared-absorbing compound, for example Pigment Green 8, wherein said infrared-absorbing compound does not create a strongly colored security image.

Printing

A method of treating a material, the method comprising the steps of: (i) contacting the material with a coloring composition comprising a dye compound; and (ii) contacting the material with a composition comprising a quaternary ammonium salt.

A depilatory composition comprising a source of cyanate ion, an organic acid or a salt thereof and a peroxide compound; and methods of removing hair from the skin using such compositions.

Composition and method

A method of treating a material, the method comprising applying to the material a composition comprising at least 10 wt % of ammonium carbonate, ammonium carbamate or a mixture thereof; and a source of hydrogen peroxide.

Bleaching methods and compositions

Flame-retardant composition containing a first component selected from phosphorous acid or a salt of phosphorous acid and a second component selected from an isocyanic acid, an isocyanic acid precursor, a cyanate salt, a thiocyanate salt or isothiocyanic acid precursor, dicyandiamide, cyanamide or carbodiimide precursor.

Phosphorus-contaning flame-retardant compositions

A method of treating a material to improve flame retardancy, the method comprising applying to the material urea, phosphorous acid or a salt thereof, and a base comprising a monovalent metallic cation.

Method and composition

A method of colouring a material, the method comprising the steps of: a)applying to the material a composition comprising a sulphur-containing nucleophile; and b)applying to the material a composition comprising a dye compound selected from a dye class other than the class of reactive dyes.

In one embodiment, the invention provides a method of removing color from dyed hair, the method comprising applying to the hair a color removal composition comprising a sulfur-containing nucleophile or a precursor thereof.

Hair treatment composition and methods

Composition including an oleophilic base ink composition having dispersed therein particles of an infrared-absorbing material wherein the infrared-absorbing material is selected from reduced indium tin oxide, titanium nitride, zirconium nitride, molybdenum metal, copper chromate, lanthanum hexaboride, neodymium oxide, neodymium chloride, dysprosium oxide and praseodymium oxide.

Security inks containing infrared absorbing metal compounds

wherein D is a chromophore; L is a linking group selected from SO, NHCO, and NHSO; Q is a hydrogen or halogen atom; and R is selected from C-Calkyl, (CH)COOH, (CH)CONH, (CH)SOH, (CH)COOM, (CH)POH, (CH)OH, (CH)SSO&#x2033;, (CH)NR, (CH)NRH, (CH)NHCOR, PhSSO&#x2033;, PhSOH, PhPOH, PhNR, PhNR, (CH)CH(SH)R(CH)COOH, and n is an integer in the range of 1 to 4 wherein within the same molecule each n is not necessarily the same integer; M is a cation of an alkaline earth metal, alkali metal, NH4+ or NR; and Ris C-Calkyl. 

New, highly multifunctional reactive dye compounds are provided. The number of leaving groups in the non-chromophoric part of the molecule added to the number of chromophore moieties is at least equal to 5, preferably in the range of from 5 to 12, more preferably from 5 to 6. The new reactive dye compounds preferably have at least two asymmetric bridges.
