Description: FIELD OF THE INVENTION This invention concerns organic materials, especially organic intermediates and colorant materials or chromophores therefrom, containing at least one poly(oxyalkylene) moiety having primary hydroxyl site enhancement or enrichment which contributes to one or more characteristics of enhanced functionality such as higher density hydroxyl distribution, increased branching and branching density, more uniform branch chain lengths, or the like, which characteristics appear to contribute to improved reactivity and/or compatibility of the present materials in polymeric substrates, as well as improvements in other properties such as non-extractibility from such substrates. In this regard, the chemical structures of the present colorants are readily tailorable to meet, in exceptional manner, the physical and chemical requirements of the specific industrial application, particularly in the coloring of formed thermosetting or thermoplastic resins and articles formed therefrom. Some of the desired physical and chemical characteristics of such colorants for coloring polymers per se or compositions containing polymer, in addition to having at least substantial tinctorial power, include one or more of excellent clarity and light fastness, high heat stability, crystal structure and shade immutability, availability as liquids or at least good resin compatibility at processing temperatures for easy blending with the polymer or compositions, easy clean-up from processing, homogeneity of dispersal in the polymer or composition, non-nucleating propensity of the colorant, and resistance to migration, settling, streaking, plating, subliming, blooming, solvent or water extractibility or the like of the colorant from the polymer or composition or article formed therefrom. DESCRIPTION OF RELATED ART Multi-functional reactants such as compounds containing poly(oxyalkylene) moieties having a plurality of hydroxyls, primary and/or secondary, are described, for example, in U.S. patents: 3,535,382; 4,761,502; 3,154,535; 4,298,764; 4,659,774; 3,446,757; 4,751,254; 4,086,151; and 3,945,894. Note, the production of primary and secondary hydroxyls through the base catalyzed polymerization of glycidol is described in the Journal of Polymer Science, Vol. 23, pages 915-949(1985), E.J. Vandenberg. The utility disclosures and process disclosures of these patents and literature reference concerning entry of the reactants into polymeric or resinous materials or substrates are incorporated herein by reference. Colorants having polyhydroxyl functionalities are particularly useful for permanent incorporation into polymeric materials or substrates such as polyurethanes as described for certain poly(oxyalklene) materials in the aforesaid U.S. Patents 4,751,254 and 3,446,757. Further, the nature of the epoxide chain propogation step influences the positions of the hydroxyl sites in the epoxide chain, their molar concentrations, and the ratio of their primary/secondary character all of which are quite important, particularly in regard to the reactivity of the colorant and its extractability from polymeric substrates. US-A-4,751,254 describes the reaction of 1-chloro-2,3-propanediol to introduce a diol structure into the poly(oxyalkylene) chain. In practice, only one mole of 1-chloro-2,3-propanediol can be added per chain. Moreover, the poly(oxyalkylene) chain in the colorants of US-A-4,751,254 were initially reacted to have ethylene oxide residues immediately adjacent the glycidol segment formed from the 1-chloro-2,3-propanediol. US-A-3,446,757 discloses high molecular weight polyethers prepared from silicon esters of epoxy alcohols, or copolymers of the silicon esters with an epoxide-containing monomer having an oxirane or acetone ring. US-A-4,086,151 refers to compounds having up to 2, substantially linear, poly(oxyalkylene) chains. In two particularly important utilities for the prior art poly(oxyalkylene) colorants, (1) the reactive, primary hydroxyls of the poly(oxyalkylene) moiety or moieties which are associated with the colorant are reacted into isocyanate based glues for carpet underlays, and (2) the colorants are reacted into polyurethanes which are formed into slab foam configuration for the production of shoe soles or the like. The carpet underlay application (1) employs an isocyanate based glue which may be colored by reaction with a polyhydroxyl containing poly(oxyalkylene) colorant. In this application, should the carpet underlay become flooded, for example, with soapy water, as in steam cleaning thereof, unreacted poly(oxyalkylene) colorant would extract from the underlay and migrate into the carpet, leaving the carpet unacceptably colored upon drying. In the second application (2) in the coloration of polyurethane shoe soles, the ratio of isocyanate is much lower than in carpet underlay production, making it more difficult to react the prior art poly(oxyalkylene) colorant during polyurethane formation. The benefits of soluble colorants, particularly when storing pre-formulations of polyol and colorant for extended periods of time prior to reaction with isocyanates and sole formation, are well recognized in the field, the problem of their insufficient reactivity, resulting in excessive migration of the colorant is highly evident from their trial uses. Consequently, the soles, although quite pleasing in appearance, tend to leave colored marks on the floor when worn due to the migration of unreacted colorant out of the system. It is noted that in these prior disclosures, the epoxide chain propagation both branched and unbranched, proceed according to the natural polymerization tendencies of the epoxide reactant, without further directive influence. As a result and as more clearly perceived through theoretical considerations, the degree of branching is thus limited and chain propagation appears to prodeed principally from primary hydroxyl nucleophilic sites, producing long, unbranched chains. Such limited branching, particularly where the residual functional sites are distributed in a low density pattern, appear to have a restricting effect on the propensity of the poly(oxyalkylene) moiety to affix itself, either ahemioally or physically by moleoular intertwining to substrates such as polymers or the like. It is further noted that substantial difficulty is encountered in reacting any secondary hydroxyls of a colorant with e.g., toluene diisocyanate for incorporation thereof into a polyurethane substrate. For such purpose, the present invention provides a means for converting the secondary hydroxyls to primary and thus markedly enhancing the reactivity of the intermediate or colorant with toluene diisocyanate or other such reactant to greatly increase the permanency of the colorant in the substrate. While this conversion of secondary to primary would appear to be straightforward through reaction with ethylene oxide, it has been found that with this reactant an unacceptably high proportion of secondary hydroxyls remain in the intermediate or colorant and result in diminished permanency of the colorant moiety in the substrate. As aforesaid, this diminished permanency is especially noticeable in the case of higher concentrations of colorant which can migrate from the substrate polymer and tranfer to rugs, furniture, or the like. SUMMARY OF THE INVENTION The present invention has as a principal object therefore, to provide a process, whereby a positive directive influence is brought to bear on such epoxide polymerizations to effect the aforesaid molecular improvements, especially the apparent branching and functional density enhancements, and particularly where the branched segments are ultimately terminated by primary hydroxyls. This and other objects hereinafter appearing have been attained in accordance with the present invention through the discovery of a process and product therefrom, which process provides the aforementioned directive influence on the epoxide polymerizations, the process comprising the steps of (1) providing a reaction system containing an initial reactant having at least one glycidol segment comprised of at least one glycidol residue and containing at least one primary hydroxyl and at least one secondary hydroxyl, and (2) sequentially contacting said reaction system with epoxide reactant material to (a) firstly produce at least one secondary hydroxyl containing epoxide residue segment linked directly to at least one primary oxy site on said glycidol segment by reacting the system with a secondary hydroxyl producing epoxide of three or more carbons, and (b) secondly to terminate at least a major portion of the resulting poly(oxyalkylene) chains or branches with primary hydroxyl groups by reacting the system with a primary hydroxyl producing epoxide. In certain preferred embodiments of the above process: (a) in step (2) said reaction system is first contacted in a step (2a) with a first epoxide reactant material of at least three carbons in stoichiometric excess of at least a major portion of total primary hydroxyl in said glycidol segment, and the resulting reaction system is then contacted in a step (2b) with a second epoxide reactant material which produces primary hydroxyls, the amount of said second epoxide reactant material added being in stoichiometric excess of at least a major portion of total secondary hydroxyls in the product of step 2a); (b) in steps (2a) and (2b) the first and second epoxide reactant materials respectively are added in stoichiometric excess of the total hydroxyl groups present in said reactant from step (1) and in the poly(oxyalkylene) moiety from step (2a); (c) the molar ratio of each of said first and second epoxide reactant materials to total glycidol residues is from about 1/1 to about 60/1, preferably from 1/1 to 50/1; (d) said glycidol segment contains two to eight glycidol residues (ie is a polyglycidol segment); and (e) said first epoxide reactant material is propylene oxide or butylene oxide or mixtures thereof, and said second epoxide reactant material is ethylene oxide. The glycidol segment is preferably linked to a chromophore or to an intermediate which may find utility in the production of colorants. In a broad sense, the present invention may be useful with virtually any organic nucelophile when the character of branching in a poly(oxyalkylene) substituent is critical. DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION Without limiting the scope of the invention, the preferred features of the invention are hereinafter set forth. The present invention provides marked improvements in reactivity of the intermediates or colorants and allows their successful use in the above and many other applications. It is believed that the present molecular improvements results from the diminishment of reactivity disparity between the available primary and secondary hydroxyls of the glycidol segment through conversion of at least some of the initial primary hydroxyls thereof to secondary hydroxyls by means of the initial reaction with the first epoxide reactant material, which reaction theoretically occurs more readily at primary hydroxyl sites. The secondary hydroxyls originally present or formed by this first reaction thus have diminished competition from primary hydroxyls for reaction with subsequent first and second epoxide reactants. Consequently, the possibility for unlimited, single, unbranched chain propagation from primary hydroxyl sites is markedly reduced. It is noted that the present process appears to distribute reactive hydroxyl functionality in the final product in a more dense spatial relationship than heretofore attainable, for subsequent and improved reaction with polymeric reactants or the like. The improved materials so produced find special utility, e.g., as reactive or blendable intermediates for permanently incorporating various organic moieties such as, for example, organic colorants as aforesaid into polymeric substrates. Such incorporation into polyurethanes is described in detail in the aforesaid U.S. patent 4,284,729. Also, the present materials find utility as aqueous dispersion aids in a variety of systems, or for reactive incorporation into compounds for markedly increasing the water dispersibility thereof. In the use of poly(oxyalkylene) materials, particularly as reactive intermediates, the degree of chain branching, the positions of the functional sites on the poly(oxyalkylene) moiety and their molar concentrations thereon, and the ratio of their primary/secondary character can become quite important, particularly in regard to the permanancy and non-extractibility with which these intermediates can chemically or physically affix various moieties, such as colorants, into various polymeric substrates. In addition to the intermediates which may be useful in the manufacture of colorants, the invention is directed to the colorants themselves having poly(oxyalkylene) moieties as set forth herein. in its broad aspect, the present invention discloses a process for preparing a compound having the formula Y-(Z) 1-6 wherein Y is the residue of an organic nucleophile; each group Z is a poly(oxyalkylene) moiety comprising at least one glycidol segment comprising at least one glycidol residue, said process comprising the steps of: 1. providing a reaction system containing an initial reactant having at least one glycidol segment comprised of at least one glycidol residue of formula -CH 2 CH(OH)CH 2 O- or -CH 2 CH(OH)CH 2 OH, said glycidol segment containing at least one primary hydroxyl group and at least one secondary hydroxyl group; 2. contacting said reaction system with a first epoxide reactant material comprised of a secondary hydroxyl producing epoxide having three or more carbon atoms; 3. contacting said reaction system with a second epoxide reactant material comprised of a primary hydroxyl producing epoxide, the addition of said epoxide reactant materials being in a selective sequence firstly to produce a secondary hydroxyl containing epoxide residue segment linked directly to at least one primary oxy site on said glycidol segment and secondly to terminate at least a major portion of the resulting poly(oxyalkylene) chains or branches with primary hydroxyl groups. At least one secondary hydroxyl of said glycidol residue segment may be linked directly to a third epoxide segment having the characteristics of said first epoxide segment or said second epoxide segment. Preferably, the third epoxide segment has a primary terminal hydroxyl. As stated in a more limited embodiment, each Z is a poly(oxyalkylene) moiety containing at least one polyglycidol segment of at least two glycidol residues, said polyglycidol segment being directly linked to a terminating moiety containing a first epoxide segment comprised of (a) the residue of one or more epoxide reactants of three or more carbons, and (b) a second epoxide segment directly linked to said first epoxide segment and comprised of the residue of one or more epoxide reactants and containing at least one primary terminal hydroxyl. The above Z moieties can vary in molecular weights, for example, from about 200 to about 10,000, depending on the use intended for these reactive materials products. The Z moieties in another preferred embodiment contain in close proximity to the nucleophile a segment of at least two linked glycidol residues, which segment has been reacted with propylene oxide or butylene oxide in stoichiometric excess of the glycidol residue hydroxyl sites, and wherein the resultant product is reacted with ethylene oxide reactant to provide at least two terminal -CH 2 CH 2 OH groups. It is also preferred that in the Z moiety the glycidol residues comprise at least about 0.5 mole percent of all epoxide residues, preferably from about 2.0 to about 30.0 mole percent, and most preferably from about 8.0 to about 22.0 mole percent. Inherent in the above described process and composition is the optional provision for reacting one or more additional glycidol molecules into the Z poly(oxyalkylene) moiety at sites separated from the initial glycidol segment. In this event, it is preferred that the additional glycidol residue be subsequently reacted with one or more molecules of a secondary hydroxyl providing epoxide, and that the product thereof subsequently be reacted with one or more molecules of a primary hydroxyl providing epoxide such as ethylene oxide.

According to the present process, the colorant may be incorporated into the resins during their preparation by simply adding the colorant to the reaction mixture or to one of the components of the reaction mixture before or during the polyaddition reaction. For example the colorant may be admixed with chain extending diols, e.g., ethylene glycol, diethylene glycol and butane diol in the case of polyester preparation. In general, it is desirable not to use more than about 20 percent by weight of colorant based on the weight of polyol. In most cases very strong colorations are produced with a small proportion of the colorant, for example, from about 0.1 to about 2 percent, preferably 0.5 to 1 percent by weight colorant based on the weight of polyol. For instance, when the thermosetting resin to be colored is a polyurethane resin the process may be carried out by adding the coloring agent in the form of a solid, solution, diespersion or liquid to the polyol or even in some instances to the polyisocyanate component of the reaction mixture either before or during polyurethane formation. The subsequent reaction may be carried out in the usual manner,ie., in the same way as for polyurethane resins which are not colored. It is particularly noted that the coloring agents produced by one embodiment of the present invention are polymeric, liquid, reactive coloring materials. As such, they may be added to the reaction mixture or to one of the components thereof in solvent-free form rather than as a of solution or dispersion in solvent or dispersing medium. Obviously, such liquids have significant processing advantages over solids in solvent systems in eliminating the need for extraneous nonreactive or reactive solvent or dispersing agent and thus the need for removing such from product. The thermosetting resins to which the process of the present invention may be applied may be made by the reaction of a nucleophile with an electrophile. Examples of such resins include alkyds, allylics, the amines, e.g., melamine and urea, epoxies, phenolics, polyesters, silicones and urethanes. These resins colored according to the present invention can be used in a variety of end uses, including moldings, sealants, elastomers, films, fibers, lacquers, coatings and foamed materials. It has been found in particular that the present colorants may be quite advantageously employed for the production of foams, such as polyurethane foams which may be soft, semi-rigid or rigid, or the so-called polyurethane integral skin and microcellular foams. Such foams are useful for producing shaped products by injection molding, extrusion or the like. The polyols may be hydroxy terminated polyesters which contain hydroxyl groups, in particular, reaction products of dihydric alcohols and dibasic carboxylic acids, or polyethers which contain hydroxyl groups, in particular products of the addition of ethylene oxide, propylene oxide, styrene oxide or epichlorohydrin to water, alcohols or amines, preferably dialcohols. The colorants produced by the present invention are, in themselves, polymeric compounds, thus they may be soluble, for instance, in most polyols which would be used in polyurethane manufacture, in most epoxy formulations, in polyester formulations, as well as in colorant admixtures. This property may be particularly valuable in that this solubility permits rapid mixing and homogeneous distribution throughout the resin, thus eliminating shading differences and streaks when properly mixed. The colorants also have greatly reduced no tendency to settle as compared to pigment dispersions. The intersolubilities of the colorants makes it possible to prepare a blend of two or more colorants to provide a wide range of colors or shades. In the use of the present primary hydroxyl enhanced compounds, which contain hydroxyls, in the production of polyurethane foams, several reactions generally take place. First an isocyanate such as toluene diisocyanate is reacted with a polyol such as polypropylene glycol in the presence of heat and suitable catalyst. If both the isocyanate and the polyol are difunctional, a linear polyurethane results, whereas should either have functionalities greater than two, a cross linked polymer will result. If the hydroxylic compound available to react with the -NCO group is water, the initial reaction product is a carbamic acid which is unstable and breaks down into a primary amine and carbon dioxide. Since excess isocyanate is typically present, the reaction of the isocyanate with the amine generated by decarboxylation of the carbamic acids occurs, and if controlled, the liberated carbon dioxide becomes the blowing agent for the production of the foam. Further, the primary amine produced also reacts with isocyanate to yield a substituted urea which affords strength and increased firmness characteristics to the polymer. In general, amine and tin catalysts are used to delicately balance the reaction of isocyanate with water, the blowing reaction, and the reaction of isocyanate with polymer building substituents. If the carbon dioxide is released too early, the polymer has no strength and the foam collapses. If polymer formation advances to rapidly a closed cell foam results which will collapse on cooling. If the colorant or another component reacts to upset the catalyst balance, poorly formed foam will result. It is particularly noted, that the present colorants are especially stable to the tin catalysts and to excess isocyanate materials employed. The present liquid reactive coloring agents may also be of considerable value in reaction injection molding (RIM) applications. The RIM process is a method of producing molded polyurethanes and other polymers wherein the two reactive streams are mixed while being poured into a mold. Upon reaction, the polymer is "blown" by chemicals to produce a foam structure. This process may be hindered by the presence of solid particles, such as conventional pigments. By comparsion, the present colorants do not effect this hinderance since there are no solid particles in the system and the colorant becomes part of the polymer through chemical reaction. Thermoplastic resins which may be used according to the present invention include a wide range of resins and synthetic resin compositions which are known in the art as being essentially thermoplastic in nature. The term "thermoplastic" is used herein in its conventional sense to mean a resin having the property of softening or fusing when heated and of hardening again when cooled" (see Webster,s Seventh Collegiate Dictionary, G & C Merriam Co., 1965). Thermoplastic resins are to be clearly distinguished both in terms of their essential physical and chemical characteristics from thermosetting resins. The term "thermosetting" used herein is also used in its conventional sense to means a resin "having the property of becoming permanently rigid when heated or cured. Examples of thermoplastic resin systems which may be employed include a wide range of polyolefin polymers, e.g., polyethylene, linear low density polyethylene, polypropylene, polybutylene and copolymers made from ethylene, propylene and/or butylene. Other thermoplastic polymers which may be employed according to the present invention include polyvinyl chloride, polyvinylidene chloride, cellulosic resins such as cellulose acetate, cellulose acetate butyrate and cellulose acetate propionate, acrylic resins such as poly(methyl methacrylate), styrene-acrylonitrile copolymer, polystyrene, polycarbonate and acrylonitrile-butadiene-styrene terpolymer(herein ABS), polyamides such as nylon 6 and nylon 66 and polyesters such as poly(ethylene terephthalate), especially glycol modified poly(ethylene terephthalate) and poly(butylene terephthalate). As mentioned above, the colorants may be employed in the thermoplastic resins in a minor amount sufficient to provide the desired degree of coloration therein. The actual amount used will, in addition to the desired depth of shade, depend upon the tinctorial strength of the chromophore used and the overall molecular weight of the colorant, e.g., chromophore plus poly(oxyalkylene) chain length. Typically the amount of colorant employed may be from about 0.001 percent to about 10 percent, preferably from about 0.01 percent to about 3 percent, and most preferably from about 0.01 to about 1.0 percent by weight based upon the overall weight of the resin composition. Other conventional additives may also be present in the resin compositions of the present invention. For instance, such additives may include plasticizers, antioxidants, stabilizers, lubricants, flame retardants, nucleating agents and other additives as will be readily recognized by those skilled in the art. In general, the present colorants have been observed to have little or no adverse interactions with these conventional additives. The colorants if used properly ordinarily do not detract from the clarity of the resin, and it has been found that additives which improve the clarity may be used in combination with colorants as described herein to provide resin products that are both colored and which also have excellent clarity. One particular class of additives which have been found to be useful in this regard are the benzylidene sorbitols including substituted benzylidene sorbitols such as those described in: U.S. Pat. No. 4,016,118 to Hamada, et al. (E.C. Chemical); U.S. Pat. No. 4,371,645 to Mahaffey (Milliken Research Corporation); and Japanese Pat. No. SHO [1977] 53-117044 to Kobsyashi, et al. (New Japan Chemical); all of these patents being hereby incorporated herein by reference. The particular shade of the colorant will depend primarily upon substituents present on the basic chromophore. A large variety of colors and shades may be obtained by blending two or more colorants. Blending the colorants of the present invention can be readily accomplished as the colorants are polymeric materials which may have substantially identical solubility characteristics dictated by the nature of the polymeric chain. Therefore, the colorants are in general soluble in one another, and are also, in general, completely compatible with each other. According to the process of the invention, the colorant may be incorporated into the thermoplastic resin using conventional techniques such as those employed to incorporate other additives in such resins. For instance, the colorant may he incorporated into the resin by simply adding it to the resin while the resin is in a plasticized or molten state, typically prior to formation of the polymer into its final shape, e.g., by molding, extrusion, blow-molding and the like. For instance, when the thermoplastic resin to be colored is a polyolefin resin the process may be carried out by adding a colorant comprised of a poly(oxyalkylene) substituted chromophore group directly to the molten polymer, by tumbling it onto a pre-extruded pelletized resin, or by mixing it into the resin powder prior to extrusion. The polymer may then be molded or extruded in the usual manner, i.e., in the same way as for polyolefin resins which are not colored. Alternatively, a concentrate of the colorant in an appropriate resin or vehicle may first be prepared. Such concentrate may contain an appropriately high percentage of colorant. The concentrates may be in the form of liquids, solids, e.g., powders, pellets, or the like, as may be desired. These may then be incorporated into the thermoplastic resin. Obviously, liquids may have certain processing advantages over solids, and moreover liquids may, if desired, be added directly to the molten polymer and therefore contain no extraneous solvent or dispersing agents. This process may, therefore, provide unusual and advantageous properties in the final thermoplastic resin product. Alternatively, however, the colorants may be premixed with minor amounts of or solvent or dispersing agent which is compatible with the resin, thus providing certain processing advantages. The highly branched intermediates and colorants of the invention are prepared in three steps. In the first step, a nucleophile, such as an aromatic amine, is hydroxyalkylated by the reaction with glycidol at about 80-150°C to give a intermediate having both primary and secondary hydroxyls. Useful nucleophiles are primary or secondary amines, hydroxy compounds, mercapto compounds, sulfinic acids, sulfonamides, imides or sulfoic acids. The glycidol is added in the presence of an inert gas such as nitrogen until the desired amount of glycidol is reacted. This base catalyzed reaction is carried out with or without solvents. If solvents are desired, toluene, xylenes, nitrobenzene, dioxane are representive solvents that may be used. Exemplary of the useful base catalysts are potassium hydroxide, lithium hydroxide, calcium hydroxide, and barium hydroxide. The amount of basic catalyst can vary but is usually in the range of from about 0.05 percent to about 2 percent by weight. In addition, certain tertiary organic amines are useful catalysts, such as dimethylaminocyclohexane, triethylamine, and benzyldimethylamine. In the second step, the intermediate from step one containing the glycidol segment is converted into a substantially solely secondary hydroxyl containing intermediate by further hydroxyalkylation with one or more alkylene oxides containing more than two carbon atoms at about 80-150°C. This reaction is carried out as in step one. In the third step, an intermediate from step two is converted into the final intermediate containing substantially solely primary hydroxyls by hydroxyethylation with ethylene oxide at about 80-150°C. The ethylene oxide is added in the presence of an inert gas such as nitrogen until the desired amount of ethylene oxide is absorbed. This reaction is carried out as in step one. The primary hydroxyl enriched aromatic colorants produced by the present invention can be prepared by many different methods depending, e.g., on the chromophoric group desired in the polymer. Some of these routes are illustrated in (I) through (VI) below. These routes are given as illustrations and are not intended to limit the scope of the present invention. In Route I the azo colorants of the invention are prepared by diazotizing carbocylic or heterocyclic amines (I) to give diazonium salts (II) which are coupled with intermediate aromatic coupling components (III) to give the azo colorants (IV) wherein Q- and -Ar are as defined above, and wherein either one or both of Q- and -Ar contain at least one -Z moiety. Various methods for diazotizing aromatic amines are known in the chemistry of azo dyes. The couplings are usually carried out in dilute mineral acids or organic acids such as acetic or propionic acid, with coupling being facilitated by addition of some base to raise the pH to a least 3-4. Intermediates containing a hydrazo functionality are set out below in Route IA. The corresponding diazonium salts (II) from Route I above are reduced with sodium sulfite in the presence of mineral acid at a temperature of about 70-100°C to form the hydrazo intermediates (IIA) of the invention. The methine colorants of the invention are prepared in according to Route II, wherein Route II comprises three steps. In the first step, primary hydroxyl enriched aromatic amine intermediate, H-Ar, is reacted with an organic acid anhydride to form the diester intermediate. Most generally, the aromatic amine intermediate, H-Ar, is reacted with acetic anhydride at a temperature within the range of about 60-130°C. Certain tertiary organic amines are useful catalysts, such as triethylamine, dimethylaminocyclohexane and benzyldimethylamine. In the second step, the aromatic diester intermediate, from step one is reacted with the Vilsmeier reagent to get the corresponding aldehydes, [Bull. Societe Chim. de France, No.10:1989-99(October 1962);Angewanate Chemie 72, No.22, 836-845,(Nov. 1960)] generally using N,N-dimethylformamide (DMF) and phosphorous oxychloride. After base hydrolysis, the corresponding aromatic aldehyde intermediate, Ar-COH is isolated. Finally, in the third step, the aromatic aldehyde intermediate Ar-COH (V) is reacted under Knoeveneagel conditions with an active methylene compound (VI) to give the methine compound (VII). The azamethine colorants of the invention are prepared in two steps according to Route III. In step one, the aromatic amine intermediate (III) is nitrosated using nitrous acid to give nitroso aromatic amine intermediates (VIII). In the second step, the nitroso aromatic amine intermediate (VIII) is reacted with an active methylene compound (VI) to give the azamethine compound (IX). The cationic azo or cationic methine colorants of the invention can be prepared by many different methods. Some of these methods are illustrated in Routes (IV) through (VI) below. These routes are given as illustrations and are not intended to limit the scope of the present invention. The azo colorants (X), where A is the residue of a heterocyclic ring, are converted to the corresponding cationic colorants (XI), by reacting with an alkylating agent at elevated temperature with or without an inert solvent. Suitable alkylating agents that can be used are dialkyl sulfates, alkyl halides, aralkyl halides, alkyl esters of sulfonic acids, activated vinyl compounds, haloacetic acids, etc. Examples of such alkylating agents include dimethyl sulfate, diethyl sulfate, dipropyl sulfate, ethyl bromide, butyl bromide, methyl iodide, ethyl iodide, benzyl chloride, benzyl bromide, methyf-p-toluene sulfonate, butyl-p-toluene sulfonate, ethyl benzenesulfonate, acrylamide, and bromoacetic acid. The cationic methine colorants of the invention are prepared in several ways as illustrated in Routes V and VI. In Route V, methine cationic colorants (XIII) of the invention are prepared by condensing substituted 2-methylene-1,3,3-trimethylindoline (Fischer's Base) (XII) with the aromatic aldehyde (V) described above at elevated temperature in the presence of a catalyst with or without an inert solvent. The base (XII), is commerically available and the condensation procedures are well known. Alternatively, cationic methines (XV) are prepared by condensing substituted quaternary bases salts (XIV) with a the aromatic aldehyde (V) described above at elevated temperature in the presence of a catalyst with or without an inert solvent. The quaternary base salts of formula (XIV) and the condensation procedures are well known. Examples of useful quaternary bases include quaternized quinolines, benzothiazoles, benzoxazoles, indolenines, and benzimidazoles. Examples of the above anion X - include Cl - , Br - ,I - , CH 3 SO 4 - , C 2 H 5 SO 4 - , or the like. The anion used depends upon the method of isolation utilized and the particular quaterizing agent employed. Intermediates having increased branching and containing aromatic amine functionality are prepared according to Routes VII through IX. Route VII involves the conversion of nitro compounds (XVI) to amine intermediates (XVII) by catalytic hydrogenation. Any suitable reduction catalyst may be used. For example, catalysts such as Raney nickel, nickel oxides, finely divided metals such as iron, cobalt, platinum, ruthenium, osmium, and rhodium may be used. Furthermore, metal catalysts supported on pumice, asbestos, Kieselguhr, alumina, silica gel or charcoal work equally as well. The amount of catalyst can vary from about 0.025 to 15 percent by weight based on the nitro intermediate used. Reduction temperatures of about 20°C to about 90°C, are suitable but temperatures of 40°C to 90°C are preferred since they may provide faster reaction times and higher yields. During the reduction of the nitro intermediates, pressures ranging from about 500 to about 1800 psi of hydrogen may be used. The reduction reaction is usually carried out in the presence of a suitable solvent. Solvents include lower alcohols such as methyl alcohol, ethyl alcohol, and isopropyl alcohol; ethers such as dioxane; hydrocarbons such as benzene, toluene, xylenes, cyclohexanes, and petroleum ether; and mixtures of lower alcohols and water such as about equal parts by weight of ethyl alcohol and water. The amount of solvent present usually varies from about 30 to about 80 percent by weight of the total mixture as solvent plus nitro compound. Route VIII involves the condensation of an acetamidosulfonyl chloride intermediate (XVIII), wherein Ar 1 is phenylene or substituted phenylene with at least a stoichiometric quantity of a aromatic amine (XVII) wherein Ar is defined above and contains at least one -Z moiety, and a inorganic base at a temperature of from about 0°C to about 100°C to form an acetamido intermediate (XIX). Further heating at 80°C to 100°C hydrolyzes the corresponding acetamido intermediate (XIX) into the polyaromatic amine intermediate (XX). Route IX involves the condensation of a nitrosulfonyl chloride intermediate (XXI), wherein Ar 1 is as defined above in Route IX, with at least a stoichiometric quantity of an aromatic amine (XVII) and an inorganic base at a temperature of from about 0°c to about 100°C to form a nitro polyaromatic intermediate (XXII). The corresponding polyaromatic amine intermediate (XXIII) is then prepared by conversion of the polyaromatic nitro intermediate (XXII) by catalytic reduction as described in Route VII above. The following examples and tables illustrate specific compounds of the present invention and their preparation. Various parts or percentages, unless otherwise stated, being by weight. The abbreviations EO, PO, and BO refer to -CH 2 CH 2 O-, -CH(CH 3 )CH 2 O-, and -CH(C 2 H 5 )CH 2 O- respectively, or to their precursor epoxide, whichever is appropriate. In the examples, GL 1 represents the unterminated glycidol residue segment and GL the terminated glycidol residue segment. The numerical designation preceding each GL 1 and GL represents the average number of glycidol residues per reactive site of the nucleophile. For example, in Examples 1 and 1A wherein the numerical designation is 1.5, in actuality one reactive site of the nitrogen will have a single glycidol residue and the other will have two such residues linked together. Also, referring to Example 1 and 1A, the terminology "1.5GL/5PO/5EO-H" means that at least one primary hydroxyl of the GL 1 segment has been reacted with a propylene oxide molecule, the propylene oxide reactant having been in the reaction system in stoichiometric excess, and that the secondary hydroxyl of each terminal PO has been reacted with an ethylene oxide molecule, the ethylene oxide reactant also having been in stoichiometric excess in the reaction system. It is noted that the numerical values "5" assigned to each of the PO and EO residues of Example 1A, also represents the average number of these residues per reactive site of the nucleophile. Example 1 In a dry 1000 ml three-neck flask equipped with nitrogen purge, heating mantle, mechanical stirrer, temperature controller and addition funnel is charged 125 grams of aniline (1.34 moles) and 0.6 gram of potassium hydroxide. The mixture is heated to 110°C with stirring with by means of the heating mantle and temperature controller. Two hundred ninety-eight grams (4.03 moles) of glycidol are slowly dropwise added through the addition funnel. The first few milliliters cause a slight temperature drop before the exotherm begins. Once it starts, the heating mantle may be removed and the exotherm controlled by the addition rate. The temperature is maintained between 110-125°C by the addition rate. After all of the glycidol is charged the reaction mixture is to post-heated for one hour. At this time the hydroxyl number is run for the aniline-3 glycidol intermediate and is found to be 905 (theory is 890).

EXAMPLE 77 This example demonstrates the improved reactivity of the enriched primary hydroxyl colorants of the invention over conventional colorants by measuring the amount of colorant that migrates from a colored polyurethane foam to a reference foam upon heating for a given time period. The colorant samples from Examples 10 and 11 are formulated into a polyether based urethane molded foam and tested according to the following procedure: 1) A colored polyurethane molded foam is prepared using the formulation shown below: Ingredient Amount Colorant 0.3g Polyol (Renesol RU6744B) 30.0g Isocyanate (Renesol RU6744A) 10.8g The mold employed is approximately 5 cm in diameter and 1 cm in depth. The above ingredients are mixed under high shear, poured into the mold, cured 15-20 minutes at room temperature and oven cured at 50°C for one hour. 2) A reference polyurethane molded foam is prepared using the the formulation shown below: Ingredient Amount Polyol (Renesol RU6744B) 30.0g Isocyanate (Renesol RU6744A) 10.8g The mold employed is also approximately 5 cm in diameter and 1 cm in depth. The above ingredients are mixed under high shear, poured into the mold, cured 15-20 minutes at room temperature and at 50°C for one hour. 3) The colored foam and uncolored reference foam are then clamped tightly together and placed in a 50°C oven for 24 hours. At the end of this period, the molded foams are separated. 4) The amount of color which migrates to the uncolored reference foam is measured via CIELAB readings from an ACS Color Computer. This migration is represented as Delta values that are obtained on an ACS Specto-Sensor. The color difference (Delta E) between the sample colored foams and and reference foams is summarized in the table below. Colorant DELTA E Example 10 1.29 Example 11 17.5 These results clearly show that the enriched primary hydroxyl colorants of the invention (Example 10) are far superior to the conventional polymeric colorants (Example 11). This test indicates that a large amount of color migrates from the sample foam (prepared from Example 11) into the uncolored reference foam, because of its poor reactivity. A production run using conventional polymeric colorants (such as Example 11) is unacceptable because color bleeding occurs. In contrast, a very low level of migration is observed for the enriched primary hydroxyl colorants of the invention (Example 10) making their use preferable in the production of colored polyurethane foams. EXAMPLE 78 This example demonstrates the increased reactivity for enriched primary hydroxyl colorants of the invention over conventional colorants by measuring the amount of colorant that extracts with acetone (or unreacted colorant). The colorant samples from Examples 32B and 33 are formulated into a scrap polyurethane foam which is glued together to make carpet padding of which the glue is also an isocyanate-polyol. The colorant is first mixed into the glue employed for binding together scrap polyurethane foam for carpet underlay. The glue itself is a type of polyurethane foam, forming a pad that is economical and firm when used to pad carpet. This colored scrap polyurethane foam is prepared and tested according to the following procedure: 1) A colored scrap polyurethane foam is prepared using the formulation shown below: Ingredient Amount Colorant (Example 32B) 10.5g Propylene Carbonate (Diluent) 15.0g Coscat 83 (Catalyst) 0.8g Scrap polyurethane foam 1875.0g Binder (3000 mw polyol) Toluene Diisocyanate Index = 4.0 15.0g The colorant from Example 33 is formulated exactly as above except that 10.0 grams of this colorant are used so that in this comparsion the colorants are calibrated at equivalent color strenghts based on their average molecular weights. In the glue, the amounts of each material are some ratio of the above weights. The ingredients are mixed thoroughly and placed in a forming pan. 2) After all the ingredients are mixture, steam is applied for five minutes. 3) The carpet underlay is removed and air dried. 4) A 10 gram piece of the colored carpet padding is extracted with 300 grams of acetone for 4 hours. 5) The amount of color that is extracted from the carpet padding is measured by using the absorbance of the solution on a Beckman DU-7 Spectrophotometer. These extraction results are summarzing in the table below: Colorant Absorbance Example 33 0.4787 Example 32B 0.0680 These results clearly show that the enriched primary hydroxyl colorants of the invention (Example 32B) are far superior to the conventional polymeric colorants (Example 33). The deeply colored extract from the carpet foam (prepared from Example 33) indicates that a large loss of color from the substrate has occurred due to poor reactivity of colorant itself. Use of these conventional polymeric colorants is unacceptable in carpet applications because color bleeding occurs when exposed to strong solvents. In contrast, a practically colorless extract is observed for the enriched primary hydroxyl colorants of the invention (Example 32B) making their use preferable for the production coloration of polyurethane foams for carpet underlay. EXAMPLE 79 This example illustrates the use of enriched primary hydroxyl colorants of the invention in polyolefin systems. The following formulations are preblended using a paddle type mixer and the colorant of Example 35: INGREDIENT Formulation 1 4MF Polypropylene resin (Exxon 9142G) 99.47% Irganox 1010 (Ciba-Geigy) 800 ppm Millad 3940 2500 ppm Calcium stearate 1000 ppm Colorant (Example 35) 1000 ppm INGREDIENT Formulation 2 4MF Polypropylene resin (Exxon 9142G) 99.62% Irganox 1010 (Ciba-Geigy) 800 ppm TiO 2 1000 ppm Calcium stearate 1000 ppm Colorant (Example 35) 1000 ppm After mixing, the formulations shown above are melt compounded on a Brabender Twin Screw Mixer with a stock temperature of 245-250°C. The compounded samples are then injection molded on a small toggle clamp machine into two-step plaques with thickness of 50 and 85 mils. Formulation #1 has good clarity and is a bright red shade.
