Abstract: The present invention relates to a process for dyeing or printing manufactured natural polymer or synthetic hydrophobic fiber materials, characterized in that it comprises using dyes of the formula (I), where R1 is hydrogen, hydroxyl or a radical —NHCO—R6, where R6 is C1-C6alkyl or unsubstituted or C1-C4alkyl- or halogen-substituted phenyl, R2 is hydrogen, hydroxyl or a radical W—R7, where W is —NHCO— or —S— and R7 is C1C6alkyl or unsubstituted or C1-C4alkyl- or halogen-substituted phenyl, R3 is hydrogen, R4 is hydrogen or hydroxyl, R5 is hydrogen, halogen, methoxy, phenoxy or phenylthio, or R3 and R4 combine to form the radical of the formula (II), where the rings A and B may independently bear further substituents, to the use of these dyes for trichromatic dyeing of manufactured natural polymer or synthetic hydrophobic fiber materials and mass dyeing of plastics materials and to producing solid on-tone combinations of plastics material and manufactured natural polymer or synthetic fiber material.
Abstract: The present invention relates to methods and compositions for removing excess dye from dyed and/or printed materials, such as, textile materials dyed with disperse dyes, by treating a dyed or printed material with an esterase. The improvements resulting form the present invention include, for example, improvements in the washfastness, the wetfastness, the crockfastness, sublimation, and/or the quality of the color, such as, brightness, of dyed and/or printed materials. The present invention also relates to methods for printing or dyeing a material by dyeing or printing the material with a combination of a dye that is affected by esterase treatment and a dye that is not affected by esterase treatment, and after dyeing or printing the material, discharging residual dye by treating the material with an esterase.
Abstract: Described is a process for lightening or partially decolorizing vat- or sulfur-dyed textile materials, which comprises treating the material with aminoalkanesulfinic acids in a neutral or weakly acidic medium, and preparations of the aminoalkanesulfinic acids for carrying out this process.

Abstract: Provided is a hair dye composition containing a direct dye (1): [wherein, R1, R2, R3, R4, R5 and R6 each represents a C1-6 alkyl group; R7 and R8 each represents a hydroxy group, a C1-6 alkyl group, a C1-6 alkoxy group, an amino group or alkylamino groups; R9 represents a hydrogen atom or a C1-6 alkyl group; and X? represents an anion]. This hair dye composition undergoes a small change in color tone even after storage because it contains the direct dye (1) which has high stability against any one of an alkali agent, oxidizing agent and reducing agent, and at the same time, has markedly high hair dyeing power and exhibits excellent light resistance, washing resistance, perspiration resistance, friction resistance and heat resistance.
Abstract: Bioprosthetic tissues are treated by immersing or otherwise contacting fixed, unfixed or partially fixed tissue with a glutaraldehyde solution that has previously been heat-treated or pH adjusted prior to its contact with the tissue. The prior heat treating or pH adjustment of the glutaraldehyde solution causes its free aldehyde concentration to decrease by about 25% or more, preferably by as much as 50%, and allows a “stabilized” glutaraldehyde solution to be obtained at the desired concentration and pH for an optimal fixation of the tissue at high or low temperature. This treatment results in a decrease in the tissue's propensity to calcify after being implanted within the body of a human or animal patient.

Abstract: The invention concerns the use of indoline derivatives of formula (I): in which R1, R2, R3, R4 and R5 independently of one another represent hydrogen or C1-4 alkyl groups, or R4 and R5 together with the oxygen atoms to which they are attached represent a C1-4 alkylenedioxy group, or of salts of such indoline derivatives, as additives to hair dyeing agents of the direct dyeing or primary intermediate/secondary intermediate type, thus producing hair dyeing with excellent color fastness characteristics.
Abstract: A method of forming a distinct pattern in an article of apparel formed of fabric, including the steps of: impregnating a viscous blocking agent into the fabric of the article of apparel in the distinct pattern; treating at least a portion of fabric surrounding the blocking agent in the distinct pattern to alter a color of the portion of fabric surrounding the blocking agent; and removing substantially all of the blocking agent from the article of apparel.
Abstract: A group of known refrigerants, (R-227ea, R-124, R-134a, R-143a, R-125, R-E125, R-E143a, R-E227ca2, R-254cb, R-600a, R-142b, R-22, R-290, R-E170, R-1270, R-1216, R-218, R-C318, R-C270), that may be combined in novel ways to produce several excellent “drop-in” substitutes for refrigerants R-12 or R-500. The performance of the preferred “drop-in” substitutes for R-12 or R-500 of the present invention often exceeds that of the refrigerant being replaced, while maintaining acceptable oil circulation with existing mineral oils used in R-12 or R-500 refrigeration and air conditioning systems.
Abstract: A process for permanently deforming keratin fibers and compositions suitable for use in this process are provided. The process includes treating keratin fibers, before and/or after mechanically deforming the keratin fibers, with an aqueous reducing composition containing a keratin reducing substance, rinsing the keratin fibers with a rinse after contact with the reducing composition, and applying to the keratin fibers an aqueous fixing composition containing an oxidizing agent, where at least one of the reducing composition, the fixing composition, or the rinse is in the form of a two-phase or multiphase system. The two phase or multiphase system contains at least one oil component and/or at least one alcohol having limited miscibility with water and is capable of being converted at least temporarily with mechanical agitation into a homogeneous system for application to hair.

Abstract: The new 7-nitro-2,1,3-benzoxadiazole compounds and 7-nitro-2,1,3-benzthiadiazole compounds of formula (I) are: Dyeing agents for keratin fibers containing these compounds and methods of dyeing hair with the dyeing agents are described.
Abstract: A reactive dye compound comprising: (a) at least one chromophore moiety; (b) at least one nitrogen-containing heterocycle; (c) a linking group to link each chromophore moiety to each nitrogen-containing heterocycle; characterised in that at least one nitrogen-containing heterocycle is substituted with at least one Y group wherein Y is a phosphonate or a borate derivative. The compounds herein have high Exhaustion Values (E), high Fixation Values (F) and high Efficiency Values (T) and show significant improvements in terms of reducing spent dyestuff in effluent, increasing dye affinity to the substrate, increasing the dye-substrate covalent bonding, increasing the ability to dye substrates at room temperature, decreasing the amount of dye that is removed during the post dyeing “soaping off process” and therefore simplifying the post dyeing “soaping off process” traditionally associated with dyeing cotton with fibre reactive dyes and reduction of staining of adjacent white fabrics.
