Abstract:
This invention relates to unsubstituted and polymeric leuco colorants for use as consumer product additives to indicate a product function by color change, to make attractive or distinctive visual effects, or to provide latent or delayed color generation. The colorants may be present in a stable, colorless state and may be transformed to an intense colored state upon exposure to certain physical or chemical changes. Alternatively, the colorants may be transformed from one color to another color upon exposure to certain physical or chemical changes. The colored form of the unsubstituted or polymeric leuco colorant may be transient, since the colorant can revert back to its colorless form or its original color after the physical or chemical activation has been removed or changed. Polymeric leuco colorants are typically comprised of at least two components: at least one leuco chromophore component and at least one polymeric component.
Abstract:
Optical lenses and methods of preparing the same, in which an active material encapsulated in resin capsules is impregnated in said lens, adjacent an optical surface thereof. The active material may be a coloring material for producing a printed color pattern in the iris or other areas of the lens, or it may be a therapeutic agent.
Abstract:
Disclosed are various embodiments for dyeing a material using a dyed nanocellulose dispersion, thereby reducing or eliminating the need for water in dyeing materials, such as fabrics and textiles. A dyed nanocellulose dispersion or gel may be prepared from wood pulp fibers using a homogenizer and a dye, wherein the dyed nanocellulose dispersion comprises nanosized cellulose fibrils. The dyed nanocellulose gel may comprise an approximate concentration of 0.5% to 6%. The dyed nanocellulose dispersion may be applied to a material, such as a fabric or textile material. The fabric or textile material can be dried resulting in a dyed material.

Abstract:
A leuco composition comprises at least one reactive leuco compound, which reactive leuco compound comprises a leuco moiety and at least one reactive moiety covalently bound to the leuco moiety. A laundry care composition comprises a laundry care ingredient and a leuco composition. A method of treating a textile comprises the steps of (i) treating a textile with an aqueous solution containing a leuco composition, (ii) optionally, rinsing the textile, and (iii) drying the textile.
Abstract:
An aqueous inkjet ink composition is disclosed and includes a dye based polymeric dispersant, an aqueous organic solvent, at least one additive and water for inkjet printing specific patterns on various texture products. The dye based polymeric dispersant is present in an amount of from 2 to 30 percent by weight of the total weight of the inkjet ink composition, the aqueous organic solvent is 15 to 65 percent by weigh, and the at least one additive less than 2 percent by weigh. The dye based polymeric dispersant, the aqueous organic solvent and the at least one additive are dissolved or dispersed in water. The present invention does not easily clog at printerhead nozzles and gets rid of a great deal of industrial waste water and a tedious and complex post treatment of water cleaning, thereby scaling down the manufacturing apparatus for digital fabric.
