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##

The present disclosure provides a compound represented by the following formula (1).

##STR00001##

The present invention refers to dyes of the formula (I) and mixtures thereof ##STR00001##
a process for their production and to their use.

This application relates to thiophene azo dyes for use as hueing agents, laundry care compositions comprising such thiophene azo dyes, processes for making such thiophene azo dyes, and laundry care compositions and methods of using the same. The thiophene azo 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. These thiophene azo 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. The thiophene azo dyes are also generally stable to bleaching agents used in laundry care compositions.

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.

A dye mixture, comprising at least one blue dyeing dye of the formula (1), wherein Q.sub.1 represents a bivalent radical of formula (4a), (4b) or (4c), wherein X.sub.1 denotes chlorine or fluorine, R.sub.1 is hydrogen or C.sub.1-C.sub.8 alkyl, R.sub.2 is hydrogen, C.sub.1-C.sub.8alkyl, C.sub.1-C.sub.4alkoxy or sulfo, Y.sub.1 is vinyl or a radical CH.sub.2CH.sub.2U and U is a leaving group removable under alkaline conditions, R.sub.3 is hydrogen or C.sub.1-C.sub.8alkyl that is unsubstituted or substituted by hydroxy, sulfo, sulfato, cyano, carboxy, C.sub.1-C.sub.4alkoxy or phenyl, r and s are each independently of the other the number 0 or 1, and t is the number 0, 1 or 2, and the sum of r, s and t is 2 or 3 and at least one yellow or red dyeing reactive dye is suitable especially for the dichromatic or trichromatic dyeing or printing of natural or synthetic polyamide fibre materials and yield dyeings or prints having good reproducibility and good all-round fastness properties. ##STR00001##

Dye mixtures based on dye(s) of formula (1) ##STR00001##
and dye(s) of formula (2) ##STR00002##
formula (3) ##STR00003##
formula (4) ##STR00004##
formula (5a) ##STR00005##
and/or formula (5b) ##STR00006##

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, Z represents any one selected from the group consisting of CN, COOR.sub.11, indanone and 1,3-dioxoindane, wherein R.sub.11 is any one selected from the group consisting of alkyl groups, aryl groups, and substituted or non-substituted heteroaryl groups. 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.

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