A leuco polymer includes a leuco monomer and an alkene. The leuco polymer has a molecular weight of at least 500 and is obtainable by polymerization of the leuco monomer and one or more alkene co-monomers. The leuco monomer consists of an alkene covalently bound to a leuco moiety and the leuco monomer has a molar extinction coefficient at a wavelength in the range 400 to 750 nm of less than 1000 M.sup.1cm.sup.1. The alkene monomer(s) have a molar extinction coefficient at a wavelength in the range 400 to 750 nm that is less than 100 M.sup.1cm.sup.1. Methods of making the leuco polymer, laundry care compositions comprising the leuco polymer and methods of treating textiles with such laundry care compositions.

Provided is a reduction dyeing method for indigo color using Nesterenkonia sp. KDB2, KDB3 and/or KDB4. The reduction dyeing method is relatively simple, efficient and allows good reproducibility, by using Nesterenkonia sp. KDB2, KDB3 and/or KDB4 bacterial strains instead of a traditional fermentation process which entails poor reproducibility and is exacting and complicated.

A chromic luminescent composition and method for fabricating the composition are disclosed. The chromic luminescent composition comprises at least one or more non-luminescent materials and one or more luminescent materials. The one or more non-luminescent materials having absorption spectra that at least partially overlap with the spectrum of incident electromagnetic radiation. The one or more luminescent materials convert at least a portion of energy of incident electromagnetic radiation to a lower energy wavelength. The one or more non-luminescent materials and the one or more luminescent materials are selected such that, when subsequently exposed to incident electromagnetic radiation, color and brightness are substantially modulated through absorption and emission as a function of incident electromagnetic radiation. Also disclosed are a chromic luminescent textile and a method for fabricating the textile.

A method for dyeing artificial fibers comprises preparing an artificial fiber, and adding a dyestuff, a crosslinking agent, and an appropriate amount of water into a tank for mixture. Then, the artificial fiber is immersed in the tank to obtain a dyed artificial fiber, and the dyed artificial fiber is pressed by a roller set. Finally, the dyed artificial fiber is dried out.

A laundry care composition including: (a) at least one laundry care ingredient and (b) a leuco composition. The laundry care composition after 30 days of storage at 25 C. provides a whiteness benefit to cotton upon washing that is greater than the initial whiteness benefit. Methods of treating textiles with such laundry care compositions.

An ink jet ink composition includes one or two or more compounds A selected from the group consisting of a compound represented by Formula (1) and a compound represented by Formula (4), one or two or more compounds B selected from the group consisting of a compound represented by Formula (2), a compound represented by Formula (3), and a compound represented by Formula (5), and water, ##STR00001## (in Formula (1) to Formula (5), R each independently represents NZ.sub.2 or OZ; R each independently represents a hydrogen atom, a sulfate group, or a sulfate; X each independently represents a hydroxyl group or a hydroxide salt; Y each independently represents a hydrogen atom, a hydroxyl group, or a hydroxide salt; and Z each independently represents a hydrogen atom or an alkyl group having 1 to 6 carbon atoms).

The present invention relates to a method of colouring polymer substrates at low temperatures. The method comprises subjecting the polymer substrate that is to be coloured to a colouring liquor comprising a solvent in which the colourant has a high solubility and then adding a solvent in which the colourant has a low solubility, typically water.

Novel inkjet ink compositions for forming an image in a form of an elastic film attached to a surface of a stretchable and/or flexible substrate and processes utilizing same for inkjet printing color images on various substrates such as colored and absorptive or impregnable stretchable materials, which are characterized by heightened efficiency in process time, ink and energy consumption, as well as products having durable, wash-fast and abrasion-fast images printed thereon by the process, are disclosed. The novel ink compositions comprise a first part, which contains a property-adjusting agent and a carrier, and a second part which contains an emulsified property-sensitive proto-elastomeric film-forming agent, a colorant and a carrier, such that the second part congeals upon contact with the property-adjusting agent. The second part is digitally applied to the substrate less than 1 second following the application of the first part to the substrate.

An article, such as an article of footwear or an article of apparel, includes an upper having a gradient-like coloring pattern. The article further includes protruding elements configured in a pattern that corresponds to the coloring pattern. The article may have a layered structure including a base layer, a coloring ink layer and a layer of protruding elements.
