Electrowetting apparatus including at least one compound selected from the group consisting of: ##STR00001##
wherein each of R.sup.1, R.sup.2, R.sup.3 and R.sup.4 is independently an alkyl group. In examples a fluid includes a dye compound selected from: ##STR00002##

Dyes of formula (1) ##STR00001##
their production and their use are described.

This invention relates to a laundry care composition comprising a laundry care ingredient and a polymeric thiophene hueing agent.

Provided are a dye compound, a composition comprising the dye compound, and a display device using the dye compound. The dye compound is represented by Formula 1.

##STR00001##

This invention relates to a laundry care composition comprising a laundry care ingredient and a polymeric thiophene hueing agent.

The present invention relates to azo dyes of formula ##STR00001##
wherein R.sub.1 denotes C.sub.1-C.sub.12 alkyl which is unsubstituted or substituted by one or more C.sub.1-C.sub.12 alkoxy groups, hydroxyl groups, amino groups, cyano groups or halogen atoms and which may be interrupted one or more times by the radical O, S, NR.sub.4, COO or OOC; R.sub.4 is hydrogen or C.sub.1-C.sub.12 alkyl; either R.sub.2 is cyano and R.sub.3 is halogen or R.sub.2 is halogen and R.sub.3 is cyano; and Ar represents a carbocyclic or heterocyclic aromatic radical, to the process for the preparation thereof, to mixtures containing said dyes and to the use thereof in dyeing or printing semi-synthetic and especially synthetic hydrophobic fiber materials, more especially textile materials.

This invention relates to heterocyclic red azo colorants for seed treatment applications. The red azo colorants contain a heterocycle that includes one nitrogen atom and one sulfur atom and are free from electron-withdrawing groups on the heterocycle. Seeds for use in horticultural/agriculture applications that are coated with the heterocyclic azo colorants provide anti-counterfeiting properties to the coated seeds. A color change phenomenon is observed when the coated seeds are exposed to an acidic material, such as vinegar, and provides evidence of the authenticity of the coated seeds. The invention also relates to agricultural formulations containing the heterocyclic red azo colorants that can be used as an anti-counterfeit agents.

The present invention relates to disperse azo dyes based on diazo components having at least one fluorine-containing substituent and an 2,6-diaminosubstituted pyridine coupling component, to a process for the preparation of such dyes and to their use in the dyeing or printing of semi-synthetic and, especially, synthetic hydrophobic fiber materials, more especially textile materials.

Disclosed is a mono-azo dichroic dye compound represented by the following Chemical Formula 1, a composition for polarizing plate, a polarizing plate, and an optical device. ##STR00001## In Chemical Formula 1, R.sub.3 represents a substituted or non-substituted heterocyclic group having 1-20 carbon atoms. The mono-azo dichroic dye compound shows excellent dichroic properties, and has excellent heat resistance and photo-resistance, and thus may be used advantageously for a dye-based polarizing plate.

Provided are an azo dye composition including an azo dye compound represented by Formula (I) and a urea compound represented by Formula (II), and a method for producing an azo dye composition. R.sup.11, R.sup.12, R.sup.13 and R.sup.14 each independently represent a hydrogen atom, a halogen atom, or an aliphatic group; R.sup.15 represents an aliphatic group; R.sup.21 and R.sup.22 each independently represent a hydrogen atom, an aliphatic group, or an aromatic group; and n represents an integer from 0 to 2. ##STR00001##
