Bis(azo-benzene) diamine monomers and a method of synthesizing the monomers are provided. The bis(azo-benzene) diamine monomers, in combination with amine reactive monomers, form polymers, such as polyimides and copolyimides, having photomechanical and thermomechanical properties.

This invention relates to colored polymer, a process for their preparation, electrophoretic fluids comprising such particles, and electrophoretic display devices comprising such fluids.

A pigment composition including: a first cholesteric liquid crystal pigment; and a second cholesteric liquid crystal pigment, wherein: the first cholesteric liquid crystal pigment is a pigment having: a center wavelength of a selective reflection band within a wavelength range of 400 nm or more and 800 nm or less; and a selective reflection bandwidth of 150 nm or less; the second cholesteric liquid crystal pigment is a pigment having a selective reflection bandwidth of 200 nm or more within a wavelength range of 400 nm or more and 800 nm or less; the selective reflection band of the first cholesteric liquid crystal pigment and a selective reflection band of the second cholesteric liquid crystal pigment at least partially overlap with each other; and a containing amount of the first cholesteric liquid crystal pigment relative to a total amount of the first cholesteric liquid crystal pigment and the second cholesteric liquid crystal pigment is more than 0% by weight and 30% by weight or less.

This invention relates to a process for the preparation of monodisperse optical and shape anisotropic polymer particles comprising monomer units of at least one reactive mesogen, such particles per se, the use of these particles for the preparation of optical, electrooptical, electronic electrochemical, electrophotographic, electrowetting and electrophoretic displays and/or devices and security, cosmetic, decorative, and diagnostic applications, and electrophoretic fluids and displays.

The present application relates to novel whitening agents for cellulosic substrates. The whitening agents are comprised of at least two constituents: at least one chromophore constituent and at least one polymeric constituent. Suitable chromophore components generally fluoresce blue, red, violet, or purple color when exposed to light, or they may absorb light to reflect these same shades. This disclosure also relates to laundry care compositions including but not limited to liquid and/or powder laundry detergent formulations and rinse added fabric softening (RAFS) compositions that comprise such whitening agents.

This application relates to thiophene azo carboxylate dyes for use as hueing agents, laundry care compositions comprising such dyes that may serve as hueing agents, processes for making such dyes and laundry care compositions and methods of using the same. The aforementioned dyes contain a formally charged moiety and are generally comprised of at least two components: at least one chromophore component and at least one polymeric component. Suitable chromophore components generally fluoresce blue, red, violet, or purple color when exposed to ultraviolet light, or they may absorb light to reflect these same shades. Such dyes are advantageous in providing a hueing effect, for example, a whitening effect to fabrics, while not building up over time and causing undesirable blue discoloration to the treated fabrics. Such dyes are also generally stable to bleaching agents used in laundry care compositions.

Bis(azo-benzene) diamine monomers and a method of synthesizing the monomers are provided. The bis(azo-benzene) diamine monomers, in combination with amine reactive monomers, form polymers, such as polyimides and copolyimides, having photomechanical and thermomechanical properties.

Provided are a method of producing a compound having a colorant structure suitable for a pigment dispersant, and a pigment dispersant, a pigment composition, a pigment dispersion, and a toner each containing the compound. The production method is a method of producing a compound in which a polymer portion and a colorant portion are bonded to each other through a linking group, the method including the steps of: (a) polymerizing a vinyl-based polymerizable monomer represented by the formula (A) with a radical initiator having a protective group by living radical polymerization to provide a polymer having the protective group at a terminal thereof; (b) hydrolyzing the protective group of the polymer having the protective group at a terminal thereof obtained by the step (a) to deprotect the polymer; and (c) bonding the deprotected polymer obtained by the step (b) and a colorant to each other through a covalent bond.

A laundry detergent composition having: (a) detersive surfactant; (b) bluing agent, and (c) a clay and soil removal/anti-redeposition agent; and (d) optionally, one or more additional laundry detergent ingredients.
