This invention relates to bis-azo colorants for use as bluing agents, laundry care compositions comprising bis-azo colorants that may serve as bluing agents, processes for making such bluing agents and laundry care compositions and methods of using the same. The bluing agents are generally comprised of at least two components: at least one chromophore component and at least one polymeric component. These bluing agents are advantageous in providing a whitening effect to fabrics, while not building up over time and causing undesirable blue discoloration to the treated fabrics.

This invention relates to polymer particles, a process for their preparation, the use of these particles for the preparation of an electrophoretic device, electrophoretic displays comprising such particle, and new polymerisable dyes.

The present invention relates to an ink comprising: a solvent having a relative permittivity, measured at a frequency of 1 kHz and a temperature of 22 C., of 3 or less and a solubility in water at 25 C. of 20 mg/L or less; and a specific azo compound.
