     FIELD OF THE INVENTION 
     This invention relates to a new 2-(1-aryloxy-ethyl)-benzene-1,4-diamine compounds and compositions containing these new compounds as primary intermediates for oxidative coloring of hair fibers. 
     BACKGROUND OF THE INVENTION 
     Coloration of hair is a procedure practiced from antiquity employing a variety of means. In modern times, the method most extensively to color hair is an oxidative dyeing process utilizing one or more oxidative hair coloring agents in combination with one or more oxidizing agents. 
     Most commonly a peroxy oxidizing agent is used in combination with one or more oxidative hair coloring agents, generally small molecules capable of diffusing into hair and comprising one or more primary intermediates and one or more couplers. In this procedure, a peroxide material, such as hydrogen peroxide, is employed to activate the small molecules of primary intermediates so that they react with couplers to form larger sized compounds in the hair shaft to color the hair in a variety of shades and colors. 
     A wide variety of primary intermediates and couplers have been employed in such oxidative hair coloring systems and compositions. Among the primary intermediates employed there may be mentioned p-phenylenediamine, p-toluenediamine, p-aminophenol, 4-amino-3-methylphenol, N,N-bis(2-hydroxyethyl)-p-phenylene diamine, 1-(2-hydroxyethyl)-4,5-diaminopyrazole and as couplers there may be mentioned resorcinol, 2-methylresorcinol, 3-aminophenol, 2,4-diaminophenoxyethanol, and 5-amino-2-methylphenol. 
     There are numerous additional requirements for oxidation dye compounds that are used to dye human hair besides the color or the desired intensity. Thus, the dye compounds must be unobjectionable in regard to toxicological and dermatological properties and must provide the desired hair color with a good light fastness, fastness to a permanent wave treatment, acid fastness and fastness to rubbing. The color of the hair dyed with the dye compounds in each case must be stable for at least 4 to 6 weeks to light, rubbing and chemical agents. Furthermore, an additional requirement is the production of a broad palette of different color shades using different developer and coupler substances. A majority of the desired shades have been produced with dyes based on p-phenylenediamine. However, the use of p-phenylenediamine is being questioned, mainly due to sensitization potential. GB 2,239,265A describes that some individuals are becoming sensitized to p-phenylenediamine and its derivatives. The proposed replacements for p-phenylenediamine have not proved entirely satisfactory. There is therefore a need for new primary intermediate compounds to meet one or more of the desired properties but not possessing the sensitization potential possessed by p-phenylenediamine, that is, which has a weaker sensitization potential than p-phenylenediamine. 
     SUMMARY OF THE INVENTION 
     It is therefore an object of this invention to provide new primary intermediate compound useful in place of p-phenylenediamine to provide a wide range of different color shades with various combinations of primary intermediates and couplers, but which has a weaker sensitization potential than p-phenylenediamine. 
     It has been discovered that the new 2-(1-aryloxy-ethyl)-benzene-1,4-diamine compounds are suitable primary intermediates for hair coloring compositions with less sensitization potential than p-phenylenediamine and systems for providing good oxidative coloration of hair and for providing acceptable light fastness, fastness to shampooing, good selectivity, fastness to perspiration and permanent wave treatment, and suitable for providing a wide variety of different color shades with various primary intermediate and coupler compounds. 
     The invention provides new 2-(1-aryloxy-ethyl)-benzene-1,4-diamine compounds of formula (1):                           
     wherein R is hydrogen, hydroxy, nitro, amino, halogen, C 1  to C 5  alkyl or haloalkyl, C 1  to C 5  alkoxy or cyclic alkoxy, C 1  to C 5  hydroxyalkyl and C 1  to C 5  hydroxyalkoxy; Ar is an aromatic group, preferably an aromatic group selected from a furanyl, thienyl, pyridinyl, phenyl, 2,3-dihydro-benzo[1,4]dioxin-5 or-6-yl or benzo[1,3]dioxol-4 or -5-yl group; and y=1 to 3. The halogen may be fluorine, chlorine, bromine or iodine, preferable fluorine or chlorine. 
     These novel primary intermediates are used to provide coloration to hair in which there is good dye uptake by the hair and provides shades or colors which are stable over a relatively long period of time. The novel primary intermediates provides for dyeing of hair to impart color or shades that possess good wash fastness and do not undergo significant changes on exposure to light, shampooing or perspiration. 
     DETAILED DESCRIPTION OF THE INVENTION 
     Preferred compounds of formula (1) of this invention are those wherein R is hydrogen, amino or C 1  to C 3  alkyl, and Ar is phenyl, pyridinyl, furanyl, 2- or 3-thienyl, 2,3-dihydro-benzo[1,4]dioxin-5 or -6-yl or benzo[1,3]dioxol-4 or -5-yl. 
     The new 2-(1-aryloxy-ethyl)benzene-1,4-diamine compounds of formula (1) of this invention can be prepared according to the following reaction sequence, where R 1  and R 2  are as defined hereinbefore.                           
     In this synthesis procedure reduction of a compound of formula (2) with a reducing agent such as sodium borohydride (NaBH 4 ) produces a compound of formula (3). Catalytic hydrogenation of the compound of formula (3) provides a compound of formula (4). By tert-butoxycarbonylation of the compound of formula (4) with di-tert-butyl dicarbonate ((Boc) 2 O) in acetonitrile gives the compound of formula (5). Subjecting the compound of formula (5) to the Mitsunobu reaction with a compound of the formula HO—Ar—(R) y  in the presence of triphenyl phosphine and diethyl azodicarboxylate or diisopropyl azodicarboxylate produces a compound of formula (6). Treatment of the compound of formula (6) with methanolic HCl results in a compound of formula (1) of this invention.

     The total amount of dye precursors (e.g., primary intermediate and coupler compounds, including the novel compounds of this invention) in the hair dyeing compositions of this invention is generally from about 0.002 to about 20, preferably from about 0.04 to about 10, and most preferably from about 0.1 to about 7.0 weight percent, based on the total weight of the hair dyeing composition. The primary intermediate and coupler compounds are generally used in molar equivalent amounts. However, it is possible to use the primary intermediate compounds in either excess or deficiency, i.e., a molar ratio of primary intermediate to coupler generally ranging from about 5:1 to about 1:5. 
     The hair dyeing compositions of this invention will contain the primary intermediate of this invention in an effective dyeing amount, generally in an amount of from about 0.001 to about 10 weight percent by weight of the hair dye composition, preferably from about 0.01 to about 5.0 weight percent. Other primary intermediates, when present, are typically present in an amount such that in aggregate the concentration of primary intermediates in the composition is from about 0.002 to about 10 weight percent, preferably from about 0.01 to about 5.0 weight percent. The coupler(s) are present in an effective dyeing concentration, generally an amount of from about 0.001 to about 10.0 weight percent by weight of the hair dye composition, preferably from about 0.01 to about 5.0 weight percent. The remainder of the hair dye composition comprises a carrier or vehicle for the couplers and primary intermediates, and comprises various adjuvants as described below. 
     Any suitable carrier or vehicle, generally an aqueous or hydroalcoholic solution, can be employed, preferably an aqueous solution. The carrier or vehicle will generally comprise more than 80 weight percent of the hair dye composition, typically 90 to 99 weight percent, preferably 94 to 99 weight percent. The hair coloring compositions of this invention may contain as adjuvants one or more cationic, anionic, amphoteric, or zwitterionic surface active agents, perfumes, antioxidants such as ascorbic acid, thioglycolic acid or sodium sulfite, chelating and sequestering agents such as EDTA, thickening agents, alkalizing or acidifying agents, solvents, diluents, inerts, dispersing agents, penetrating agents, defoamers, enzymes, and other dye agents (e.g., synthetic direct and natural dyes). These adjuvants are cosmetic additive ingredients commonly used in compositions for coloring hair. 
     The hair dye compositions of the present invention are used by admixing them with a suitable oxidant, which reacts with the hair dye precursors to develop the hair dye. Any suitable oxidizing agent can be employed in the hair dye product compositions of this invention, particularly hydrogen peroxide (H 2 O 2 ) or precursors therefor. Also suitable are urea peroxide, the alkali metal salts of persulfate, perborate, and percarbonate, especially the sodium salt, and melamine peroxide. The oxidant is usually provided in an aqueous composition generally referred to as the developer composition, which normally is provided as a separate component of the finished hair dye product and present in a separate container. The developer composition may also contain, to the extent compatible, various ingredients needed to form the developer composition, i.e., peroxide stabilizers, foam formers, etc., and may incorporate one or more of the adjuvants referred to above, e.g., surface active agents, thickeners, pH modifiers, etc. Upon mixing the hair coloring composition and the developer composition to form a hair dye product composition, the adjuvants are provided in the hair dye product composition as it is applied to the hair to achieve desired product attributes, e.g., pH, viscosity, rheology, etc. 
     The form of the hair dye product compositions according to the invention can be, for example, a solution, especially an aqueous or aqueous-alcoholic solution. However, the form that is preferred is a thick liquid, cream, gel or an emulsion whose composition is a mixture of the dye ingredients with the conventional cosmetic additive ingredients suitable for the particular preparation. 
     Suitable conventional cosmetic additive ingredients useful in the hair dye and developer compositions, and hence in the hair dye product compositions of this invention are described below, and may be used to obtain desired characteristics of the hair dye, developer and hair dye product compositions. 
     Solvents: In addition to water, solvents that can be used are lower alkanols (e.g., ethanol, propanol, isopropanol, benzyl alcohol); polyols (e.g., carbitols, propylene glycol, hexylene glycol, glycerin). See WO 98/27941 (section on diluents) incorporated by reference. See also U.S. Pat. No. 6,027,538 incorporated by reference. Under suitable processing, higher alcohols, such as C8 to C18 fatty alcohols, especially cetyl alcohol, are suitable organic solvents, provided they are first liquified by melting, typically at low temperature (50 to 80° C.), before incorporation of other, usually lipophilic, materials. 
     The organic solvents are typically present in the hair dye compositions in an amount of from about 5 to about 30% by weight of the hair dye composition. Water is usually present in an amount of from about 5 to about 90% by weight of the hair dye composition, preferably from about 15 to about 75% by weight and most preferably from about 30 to about 65% by weight. 
     Surfactants: These materials are from the classes of anionic, cationic, amphoteric (including zwitterionic surfactants) or nonionic surfactant compounds. (Cationic surfactants, generally included as hair conditioning materials, are considered separately below.) Suitable surfactants, other than cationic surfactants, include fatty alcohol sulfates, ethoxylated fatty alcohol sulfates, alkylsulfonates, alkylbenzensulfonates, alkyltrimethylammonium salts, alkylbetaines, ethoxylated fatty alcohols, ethoxylated fatty acids, ethoxylated alkylphenols, block polymers of ethylene and/or propylene glycol, glycerol esters, phosphate esters, fatty acid alkanol amides and ethoxylated fatty acid esters, alkyl sulfates, ethoxylated alkyl sulfates, alkyl glyceryl ether sulfonates, methyl acyl taurates, acyl isethionates, alkyl ethoxy carboxylates, fatty acid mono- and diethanolamides. Especially useful are sodium and ammonium alklyl sulfates, sodium and ammonium ether sulfates having 1 to 3 ethylene oxide groups, and nonionic surfactants sold as Tergitols, e.g., C11-C15 Pareth-9, and Neodols, e.g., C12-C15 Pareth-3. They are included for various reasons, e.g., to assist in thickening, for forming emulsions, to help in wetting hair during application of the hair dye product composition, etc. Amphoteric surfactants include, for example, the asparagine derivatives as well betaines, sultaines, glycinates and propionates having an alkyl or alkylamido group of from about 10 to about 20 carbon atoms. Typical amphoteric surfactants suitable for use in this invention include lauryl betaine, lauroamphoglycinate, lauroamphopropionate, lauryl sultaine, myristamidopropyl betaine, myristyl betaine, stearoamphopropylsulfonate, cocamidoethyl betaine, cocamidopropyl betaine, cocoamphoglycinate, cocoamphocarboxypropionate, cocoamphocarboxyglycinate, cocobetaine, and cocoamphopropionate. Reference is made to WO 98/52523 published Nov. 26, 1998 and WO 01/62221 published Aug. 30, 2001, both incorporated herein by reference thereto. 
     The amount of surfactants in the hair dye compositions is normally from about 0.1% to 30% by weight, preferably 1% to 15% by weight. 
     Thickeners: Suitable thickeners include such as higher fatty alcohols, starches, cellulose derivatives, petrolatum, paraffin oil, fatty acids and anionic and nonionic polymeric thickeners based on polyacrylic and polyurethane polymers. Examples are hydroxyethyl cellulose, hydroxymethylcellulose and other cellulose derivatives, hydrophobically modified anionic polymers and nonionic polymers, particularly such polymers having both hydrophilic and hydrophobic moieties (i.e., amphiphilic polymers). Useful nonionic polymers include polyurethane derivatives such as PEG-150/stearyl alcohol/SDMI copolymer. Suitable polyether urethanes are Aculyn® 22, 44 and Aculyn® 46 polymers sold by Rohm &amp; Haas. Other useful amphiphilic polymers are disclosed in U.S. Pat. No. 6,010,541 incorporated by reference. See also WO 01/62221 mentioned above. Examples of anionic polymers that can be used as thickeners are acrylates copolymer, acrylates/ceteth-20 methacrylates copolymer, acrylates/ceteth-20 itaconate copolymer, and acrylates/beheneth-25 acrylates copolymers. In the case of the associative type of thickeners, e.g., Aculyns 22, 44 and 46, the polymer may be included in one of either the hair dye composition or the developer composition of the hair dye product and the surfactant material in the another. Thus, upon mixing of the hair dye and developer compositions, the requisite viscosity is obtained. The thickeners are provided in an amount to provide a suitably thick product as it is applied to the hair. Such products generally have a viscosity of from 1000 to 100000 cps, and often have a thixotropic rheology. 
     pH Modifying agents: Suitable materials that are used to adjust pH of the hair dye compositions include alkalizers such alkali metal and ammonium hydroxides and carbonates, especially sodium hydroxide and ammonium carbonate, ammonia, organic amines including methylethanolamine, aminomethylpropanol, mono-, di-, and triethanolamine, and acidulents such as inorganic and inorganic acids, for example phosphoric acid, acetic acid, ascorbic acid, citric acid or tartaric acid, hydrochloric acid, etc. See U.S. Pat. No. 6,027,538 incorporated by reference. 
     Conditioners: Suitable materials include silicones and silicone derivatives; hydrocarbon oils; monomeric quaternary compounds, and quaternized polymers. Monomeric quaternary compounds are typically cationic compounds, but may also include betaines and other amphoteric and zwitterionic materials that provide a conditioning effect. Suitable monomeric quaternary compounds include behentrialkonium chloride, behentrimonium chloride, benzalkonium bromide or chloride, benzyl triethyl ammonium chloride, bis-hydroxyethyl tallowmonium chloride, C12-18 dialkyldimonium chloride, cetalkonium chloride, ceteartrimonium bromide and chloride, cetrimonium bromide, chloride and methosulfate, cetylpyridonium chloride, cocamidoproypl ethyldimonium ethosulfate, cocamidopropyl ethosulfate, coco-ethyldimonium ethosulfate, cocotrimonium chloride and ethosulfate, dibehenyl dimonium chloride, dicetyldimonium chloride, dicocodimonium chloride, dilauryl dimonium chloride, disoydimonium chloride, ditallowdimonium chloride, hydrogenated tallow trimonium chloride, hydroxyethyl cetyl dimonium chloride, myristalkonium chloride, olealkonium chloride, soyethomonium ethosulfate, soytrimonium chloride, stearalkonium chloride, and many other compounds. See WO 98/27941 incorporated by reference. Quaternized polymers are typically cationic polymers, but may also include amphoteric and zwitterionic polymers. Useful polymers are exemplified by polyquaternium-4, polyquaternium-6, polyquaternium-7, polyquaternium-8, polyquaternium-9, polyquaternium-10, polyquaternium-22, polyquaternium-32, polyquaternium-39, polyquaternium-44 and polyquaternium-47. Silicones suitable to condition hair are dimethicone, amodimethicone, dimethicone copolyol and dimethiconol. See also WO 99/34770 published Jul. 15, 1999, incorporated by reference, for suitable silicones. Suitable hydrocarbon oils would include mineral oil. 
     Conditioners are usually present in the hair dye composition in an amount of from about 0.01 to about 5% by weight of the composition. 
     Direct Dyes: The hair dyeing compositions according to the invention can also contain compatible direct dyes including Disperse Black 9, HC Yellow 2, HC Yellow 4, HC Yellow 15, 4-nitro-o-phenylenediamine, 2-amino-6-chloro-4-nitrophenol, HC Red 3, Disperse Violet 1, HC Blue 2, Disperse Blue 3, and Disperse Blue 377. These direct dyes can be contained in the hair coloring compositions of the invention in an amount of from about 0.05 to 4.0 percent by weight. 
     Natural ingredients: For example, proteins and protein derivatives, and plant materials such as aloe, chamomile and henna extracts. 
     Other adjuvants include polysaccharides, alkylpolyglycosides, buffers, chelating and sequestrant agents, antioxidants, and peroxide stabilizing agents as mentioned in WO 01/62221, etc. 
     The adjuvants referred to above but not specifically identified that are suitable are listed in the International Cosmetics Ingredient Dictionary and Handbook, (Eighth Edition) published by The Cosmetics, Toiletry, and Fragrance Association, incorporated by reference. In particular reference is made to Volume 2, Section 3 (Chemical Classes) and Section 4 (Functions) are useful in identifying a specific adjuvant to achieve a particular purpose or multipurpose. 
     The above-mentioned conventional cosmetic ingredients are used in amounts suitable for their functional purposes. For example, the surfactants used as wetting agents, associative agents, and emulsifiers are generally present in concentrations of from about 0.1 to 30 percent by weight, the thickeners are useful in an amount of from about 0.1 to 25 percent by weight, and the hair care functional materials are typically used in concentrations of from about 0.01 to 5.0 percent by weight. 
     The hair dyeing product composition as it is applied to the hair, i.e., after mixing the hair dye composition according to the invention and the developer, can be weakly acidic, neutral or alkaline according to their composition. The hair dye compositions can have pH values of from about 6 to 11.5, preferably from about 6.8 to about 10, and especially from about 8 to about 10. The pH of the developer composition is typically acidic, and generally the pH is from about 2.5 to about 6.5, usually about 3 to 5. The pH of the hair dye and developer compositions is adjusted using a pH modifier as mentioned above. 
     In order to use the hair coloring composition for dyeing hair, the above-described hair coloring compositions according to the invention are mixed with an oxidizing agent immediately prior to use and a sufficient amount of the mixture is applied to the hair, according to the hair abundance, generally from about 60 to 200 grams. Some of the adjuvants listed above (e.g., thickeners, conditioners, etc.) can be provided in the dye composition or the developer, or both, depending on the nature of the ingredients, possible interactions, etc., as is well known in the art. 
     Typically, hydrogen peroxide, or its addition compounds with urea, melamine, sodium borate or sodium carbonate, can be used in the form of a 3 to 12 percent, preferably 6 percent, aqueous solution as the oxidizing agent for developing the hair dye. Oxygen can also be used as the oxidizing agent. If a 6 percent hydrogen peroxide solution is used as oxidizing agent, the weight ratio of hair coloring composition and developer composition is 5:1 to 1:5, but preferably 1:1. In general, the hair dyeing composition comprising primary intermediate(s) and coupler(s), including at least one of the compounds of formula (1), is prepared and then, at the time of use, the oxidizing agent, such as H 2 O 2 , contained in a developer composition is admixed therewith until an essentially homogenous composition is obtained, which is applied shortly after preparation to the hair to be dyed and permitted to remain in contact with the hair for a dyeing effective amount of time. The mixture of the oxidizing agent and the dye composition of the invention (i.e., the hair dye product composition) is allowed to act on the hair for about 2 to about 60 minutes, preferably about 15 to 45, especially about 30 minutes, at about 15 to 50° C., the hair is hair rinsed with water, and dried. If necessary, it is washed with a shampoo and rinsed, e.g., with water or a weakly acidic solution, such as a citric acid or tartaric acid solution. Subsequently the hair is dried. Optionally, a separate conditioning product may also be provided. 
     Together the hair dye composition of the present invention comprising the hair dye primary intermediate (1) and the developer composition comprising the oxidizing agent form a system for dyeing hair. This system may be provided as a kit comprising in a single package separate containers of the hair dye composition, the developer, the optional conditioner or other hair treatment product, and instructions for use. 
     Especially useful primary intermediates of formula (1) of this invention will provide hair coloring compositions having outstanding color fastness, especially light fastness, fastness to washing and fastness to rubbing. 
     Dyeing Example 1
