The present invention may suitably comprise, consist of, or consist essentially of, the aforementioned components. The invention illustratively disclosed herein suitably may be practiced in the absence of any component or substituent group which is not specifically disclosed or enumerated herein. The term hydrocarbyl as employed herein means any aliphatic, cycloaliphatic, aromatic, aryl substituted aliphatic or cycloaliphatic, or aliphatic or cycloaliphatic substituted aromatic groups. Likewise, the term hydrocarbyloxy means a hydrocarbyl group having an oxygen linkage between it and the element to which it is attached. The term divalent hydrocarbyl group refers to the aforementioned hydrocarbyl groups minus an additional hydrogen atom. The aliphatic and cycloaliphatic groups can be saturated or unsaturated. These hydrocarbyl groups can also contain substituent groups such as halogens including chlorine bromine, fluorine, iodine, nitro, nitrile. Also, these groups can be specifically free of any one or more of such substituent groups. In any of the formulas employed herein, the cyclic group with an S in the middle of the ring indicates a saturated or unsaturated cyclohexyl group wherein the cyclohexyl group can contain one or two unsaturated groups in the ring. The advanced resins of the present invention can be either terminated in epoxy groups or phenolic hydroxyl groups as desired. The advanced resins of the present invention can be prepared by reacting the appropriate epoxy resin with the appropriate phenolic hydroxyl-containing compound at a temperature of from 25°C to 280°C, preferably from 75°C to 240°C, more preferably from 100°C to 220°C for a time sufficient to complete the reaction, usually from 0.025 to 48, preferably from 0.05 to 24, more preferably from 0.01 to 10, hours. Higher reaction temperatures require less time than the lower reaction temperatures. The pressure is not particularly significant except that the reaction is conducted at pressures which will maintain the reactive components and any solvents or reaction medium employed in the liquid phase. At temperatures below 25°C, little or no reaction occurs. At temperatures above 28θ°C, gelation of the reaction mixture occurs and the resin undergoes degradation. The epoxy resin and the phenolic hydroxyl- containing compound are employed in amounts which provide a ratio of phenolic hydroxyl groups to epoxide groups of from 0.5:1 to 2:1, preferably from 0.7:1 to 1:1, more preferably from 0.75:1 to 0.95:1. In those instances wherein the phenolic hydroxyl groups are present in excess, the majority of the product will be terminated in phenolic hydroxyl groups; whereas in those instances wherein the epoxy groups are present in excess, the majority of the product will be terminated in epoxide groups. When the ratio of phenolic hydroxyl groups to epoxide group is less than 0.5:1, an excess of unreacted diglycidyl ether remains in the reaction product. When the ratio of phenolic hydroxyl groups to epoxide group is greater than 2:1, an excess of unreacted diphenol remains in the reaction product. If desired, the advanced resins can be prepared employing catalytic quantities of a suitable catalyst for the reaction between the epoxide groups and the phenolic hydroxyl groups. Representative examples of such catalysts include metal hydroxides, tertiary amines, phosphines, quaternary ammonium and phosphonium compounds, combinations thereof. Preferred such catalysts include, for example, ethyltriphenylphosphonium chloride, ethyltriphenylphosphonium bromide, ethyltriphenyl 5 phosphonium iodide, ethyltriphenylphosphonium acetate«acetic acid complex, ethyltriphenylphosphonium phosphate, tetrabutylphosphonium chloride, tetrabutylphosphonium bromide, tetrabutylphosphonium iodide, tetrabutylphosphonium acetate«acetic acid 0 complex, tetrabutylphosphonium phosphate, triphenylphosphine, N-methylmorpholine, sodium hydroxide, potassium hydroxide, tetrabutyammonium halide, benzyltrimethylammonium chloride _- butyltriphenylphosphoniumtetrabromo bisphenate, butyltriphenylphosphonium bisphenate, butyltriphenylp"hosphonium bicarbonate, triethylamine, tripropylamine, tributylamine, 2-methylimidazole, combinations thereof. These catalysts are employed in 0 catalytic amounts and the particular amount depends upon the particular reactants and catalyst being employed. However, usually the amount is from 0.0001 to 10, preferably from 0.05 to 1, more preferably from 0.1 to 0.5, percent by weight based upon the weight of the epoxy resin. If desired, the advancement reaction can be conducted in the presence of a solvent such as, for example, alcohols, glycol ethers, aromatic hydrocarbons, aliphatic hydrocarbons, ketones, amides, sulfones, cyclic ethers, any combination thereof.

Suitable epoxy resins which can be employed to prepare the advanced resins of the present invention (the resins represented by the aforementioned formulas IA, IB, IC, and ID) include those represented by the aforementioned formula IE and the following formula II and III Formulaϋ 0 0 / \ / \ H2C C-CH2-O γ2 O-CH2-C CH 2 R Formula III 0 H 2 C C-CH2 - 0-CH-(CH 2 )n2 " 0-Y2-04- (CH 2 ) n 2-CH-0 R 0 / \ H 2 C C-CH 2 wherein R, R', Y2, γ3, a , and n2 are as hereinbefore defined. The glycidyl ethers of the oxyalkylated diols are produced by the condensation of an epihalohydrin with an oxyalkylated polyol represented by the following Formula IV: Formula IV H 4-0-CH-(CH2)n2-4- O-Z-0 CH 2 ) n 2-CH-0 H wherein Z is Y2 or 3 and R 1 , Y 2 , γ3, a an n2 are defined as hereinbefore. The resulting halohydrin product is then dehydrohalogenated by known methods with a basic acting substance, such as sodium hydroxide to produce the corresponding diglycidyl ether. The oxyalkylated diols of Formula IV are produced by reacting a diol of the following Formula V H0-Z-0H (Formula V) wherein Z is defined as hereinbefore, with the appropriate molar ratio of ethylene oxide, propylene oxide, butylene oxide, tetrahydrofuran, styrene oxide or an alkyl or aryl glycidyl ether or mixtures thereof. Combinations of these oxides added in sequential manner can also be use-d so as to form block copolymers rather than random polymers. Examples of useful diols include, bisphenol A, bisphenol F, hydroquinone, dihydroxydiphenyl oxide, resorcinol, p-xylenol, poly(bisphenol A)ether of ethylene glycol, poly(bisphenol F)ether of ethylene glycol, bisphenol capped epoxy resin, 1 ,3-cyclohexanediol, 1,4- cyclohexanediol, 1 ,4-cyclohexanedimethanol, hydrogenated bisphenol A, hydrogenated bisphenol F, butanediol, hexanediol, ethylene glycol, propylene glycol, neopentyl glycol, and any combination thereof. Some of the common methods of synthesis of the diglycidylethers of aliphatic diols produce significant amounts of organic chloride-containing impurities. However, other processes are known for preparing products with lower levels of such impurities. While the low-chloride resins are not required for the practice of this invention, they can be used, if desired, for possible improvements in the process of preparing the resins, in the storage properties of the resins or formulated coatings made therefrom or in the performance properties of the products. Particularly suitable epoxy resins include, for example, the diglycidyl ethers of biphenol, bisphenol A, bisphenol F, bisphenol K, bisphenol AP (1,1-bis(4- hydroxyphenyl)-1-phenyl ethane), 1,2-bis(3- hydroxyphenoxy)ethane, 1 ,4-bis(3-hydroxyphenoxy)butane, 1 ,4-bis(4-hydroxyphenoxy)butane, 1 ,8-bis(3- hydroxyphenoxy)octane, 1 ,8-bis(4-hydroxyphenoxy)octane, 1 , 10-bis(4-hydroxyphenoxy)decane, 1 , 12-bis(4- hydroxyphenoxy)decane, the reaction product of bisphenol A or bisphenol F with from 2 to 6 moles of propylene oxide or ethylene oxide, poly(bisphenol A)ether of ethylene glycol, poly(bisphenol F)ether of ethylene glycol, any combination thereof. Suitable phenolic hydroxyl-containing compounds which can be employed herein include, for example, those represented by the aforementioned formula IB and following formula VIA or VIB Formula VIA HO — Y l OH Formula VIB HO — Y2 OH wherein Yl and Y 2 are as previously defined. Particularly suitable phenolic hydroxyl- containing compounds which can be employed herein include, for example, biphenol, bisphenol A, bisphenol F, bisphenol K, bisphenol AP ( 1, 1-bis(4-hydroxyphenyl)- 1-phenyl ethane), 1 ,2-bis(3-hydroxyphenoxy)ethane, 1,4- bis(3-hydroxyphenoxy)butane, 1,4-bis(4- hydroxyphenoxy)butane, 1 ,8-bis(3-hydroxyphenoxy)octane, 1 ,8-bis(4-hydroxyphenoxy)octane, 1 , 10-bis(4- hydroxyphenoxy)octane, 1 , 12-bis(4- hydroxyphenoxy)dodecane, pol (bisphenol A)ether of ethylene glycol, poly(bisphenol F)ether of ethylene glycol, any combination thereof. Most of the phenols are well known as well as the procedures for their preparation. However, those wherein A is an -0-Rl-O- or an -(0-CH2-CHR2) n -0- group can be prepared by reacting a catechol, hydroquinone, resorcinol, bisphenol A, bisphenol F, or bisphenol K with the appropriate dihalogen containing compound, i.e. those represented by the formulas Hal-Rl-Hal or Hal-CH 2 -CHR2-(0-CH 2 -CHR2) n 4-Hal; wherein Rl and R2 are as hereinbefore defined, Hal is a halogen, preferably chlorine or bromine and n has a value from zero to 9, at a temperature of from 0°C to 200°C. preferably from 25°C to 150°C, more preferably from 50°C to 125°C, in the presence of a hydrogen halide scavenging compound for a time sufficient to complete the reaction, usually from 0.1 to 24, preferably from 0.5 to 10, more preferably from 1 to 5, hours. The higher reaction temperatures require less time to complete the reaction whereas the lower temperatures require more time to complete the reaction. The reaction is usually conducted in the presence of water or ethanol so as to reduce the viscosity of the slurried reaction mixture and make it more susceptible to stirring by conventional means. The particular amount of water being that amount which provides the -desired stirring viscosity, and can vary from as little as 2 to as much as 30, preferably from 3 to 20, more preferably from 5 to 10, percent by weight based upon the amount of phenolic hydroxyl-containing compound employed. The particular amount of ethanol can vary from 2 to 500, preferably from 10 to 200, more preferably from 50 to 150 percent by weight based upon the amount of phenolic hydroxyl-containing compound employed. At temperatures below 0°C, little or no reaction occurs. At temperatures above 200°C, the yield significantly decreases as a result of side reactions. Hydrogen halide scavenging compounds which can be employed herein include, for example, alkali metal hydroxides, alkali metal car ' bonates, alkaline earth metal hydroxides, alkaline earth metal carbonates. Preferred hydrogen halide scavenging compounds include, for example, sodium hydroxide, potassium hydroxide, lithium hydroxide, any combination thereof. In those instances where it is desirable to have a water-borne coating composition, the advanced resin can be rendered water compatible i.e. water soluble or miscible. This can be accomplished by 5 reacting the advanced resins of the present invention including mixtures of these advanced resins with a different epoxy resin having an average of more than one vicinal epoxide group per molecule with one or more _,„ nucleophilic compounds. The nucleophilic compound is suitably " employed in an amount sufficient to convert at least a portion of the epoxy groups to cationic groups or cation-forming 15 groups. When the nucleophilic compound is added to the epoxy-containing compound in the presence of an acid, a cationic group is formed. When the nucleophilic compound is added to the epoxy-containing compound in the absence of an acid, an adduct of the epoxy- 0 containing compound and the nucleophilic compound is formed which is a cation-forming group which forms a cationic group when an acid is added. c The nucleophilic compound is usually employed in an amount which provides a ratio of moles of nucleophilic compound per epoxide group of from 0.15:1 to 1.1:1, preferably from 0.4:1 to 1:1, more preferably from 0.7:1 to 0.9:1, in the presence of a Brδnsted acid. 0 At ratios of moles of nucleophilic compound per epoxide group less than 0.15:1, an unstable aqueous dispersion is usually obtained because it has a low charge density. At ratios of moles of nucleophilic compound per epoxide group greater than 1.1:1 an aqueous solution is usually obtained. Whether this stoichiometry results in an aqueous solution or dispersion depends upon the molecular weight of the epoxy resin. With a low (<2,000) number average molecular weight epoxy resin, the 1.1:1 stoichiometry gives a solution in most instances. With a high (>2,000) number average molecular weight epoxy resin, the 1.1:1 stoichiometry may give a dispersion rather than a solution. The reaction is usually conducted at temperatures of from 25°C to 110°C, preferably from 60°C to 100°C, more preferably from 70°C to 90°C, for a time sufficient to complete the desired reaction, usually from 0.5 to 24, preferably from 1 to 12, more preferably from 2 to 8, hours. The higher reaction temperatures require less time than the lower reaction temperatures. At temperatures below 25°C, the reaction is too slow to be practical. At temperatures above 110°C, the reaction is often accompanied by undesirable side reactions. For water-borne systems, the charge density of the solid resin is used to determine the quantity of nucleophilic compound per epoxy group contained in the epoxy resin. The charge density is the milliequivalents of nucleophilic compound per gram of solid. A larger charge density is required for a high molecular weight epoxy resin than a low epoxy resin to obtain a dispersion. For the same molecular weight epoxy resin, a low charge density gives an aqueous dispersion whereas a higher charge density may give an aqueous solution. The charge density may vary from 0.08 to 1.4, preferably from 0.35 to 0.6, more preferably from 0.35 to 0.45, milliequivalents of nucleophilic compound per gram of solid. The ratio of epoxy-containing reactant/ nucleophilic compound/Brδnsted acid is variable so long as the reaction mixture is at neutral or acid pH. Stoichiometry of the reaction requires 1 equivalent of nucleophilic compound and 1 equivalent of acid per vicinal epoxy group converted. In order to form the instant nucleophilic compounds from strong acids, an excess of the nucleophilic compound is required. With weaker acids, good results can be achieved by using substantially stoichiometric amounts of reactants although a slight excess or deficiency of the epoxy- containing reactant or pyridine can be used. With still weaker acids a slight excess of acid is preferred to maximize the yield of nucleophilic compound salts. Good results have been achieved using a ratio of 1.1 equivalents of weak acid and one equivalent of nucleophilic compound per epoxide equivalent. The amount of water that is included in the reaction mixture, for water-borne compositions, can be varied to convenience so long as there is sufficient acid and water present to stabilize nucleophilic compound salt formed during the course of the reaction. Normally, it has been found preferably to include water in the reaction in amounts of from 10 to 30 moles per epoxy equivalent. The aqueous compositions of the present invention can also contain any amount of an organic solvent such as ethylene glycol monobutyl ether. These solvents are usually employed in amounts of from 1 to 75, preferably from 4 to 35, more preferably from 6 to 18, percent by weight based upon the weight of the aqueous dispersion or solution. Usually, the Brόnsted acid is employed in amounts which provides a ratio of moles of acid to moles of nucleophilic compound of from 0.2:1 to 10:1, preferably from 0.5:1 to 1.5:1, more preferably from 1:1 to 1.1:1.

Substantially any organic acid, especially a carboxylic acid, can be used in the conversion reaction to form onium salts so long as the acid is sufficiently strong to promote the reaction between the nucleophilic compound and the vicinal epoxide group(s) on the resinous reactant. In the case of the salts formed by addition of acid to a secondary amine-epoxy resin reaction product, the acid should be sufficiently strong to protonate the resultant amine product to the extent desired. Suitable Brδnsted acids which can be employed include any such acid or combination of acids which promotes the reaction between the pyridine compound and the epoxide group and provides a compatible anion in the final product. By "compatible anion", it is meant one which exists in close association with the cationic nitrogen of the pyridine compound for an indefinite period. Monobasic acids are usually preferred. The Bronsted acids can be inorganic or inorganic acids. Preferred inorganic acids which can be employed include, for example, phosphoric acid, hydrochloric, acid, hydrobromic acid, nitric acid, sulfuric acid, any combinations thereof. Organic acids which can be employed herein include, for example, those saturated or unsaturated acids having from 2 to 30, preferably from 2 to 6, more preferably from 2 to 3 carbon atoms. Also suitable are the hydroxy-functional carboxylic acids (e.g., glycolic acid, lactic acid, etc.) and organic sulfonic acids (e.g., methanesulfonic acid). The preferred organic acids include, for example, acetic acid, propionic acid, acrylic acid, methacrylic acid, itaconic acid, ethanesulfonic acid, decanoic acid, triacontanoic acid, lactic acid, any combination thereof. The conversion reaction to form cationic resins is normally conducted by merely blending the reactants together and maintaining the reaction mixture at an elevated temperature until the reaction is complete or substantially complete. The progress of the reaction is easily monitored. The reaction is normally conducted with stirring and is normally conducted under an atmosphere of inert gas (e.g., nitrogen). Satisfactory reaction rates occur at temperatures of from 25°C to 100°C, with preferred reaction rates being observed at temperatures from 60° to 100°C. Good results can be achieved by using substantially stoichiometric amounts of reactants although a slight excess or deficiency of the epoxy- containing resin or the nucleophilic compounds can be used. With weak acids, useful ratios of the reactants range from 0.5 to 1.0 equivalent of nucleophilic compounds per epoxide group of the resin and 0.4 to 1.1 10 equivalents of organic acid per epoxide. These ratios, when combined with the preferred epoxide content resins described above, provide the desired range of cationic charge density required to produce a stable dispersion _._- of the coating composition in water. With still weaker acids (e.g., a carboxylic acid, such as acetic acid) a slight excess of acid is preferred to maximize the yield of onium salts. In preparing the compositions in which the cationic group being formed is an onium group, the 0 acid should be present during the reaction of the nucleophilic compounds and the epoxy group of the resin. When the nucleophilic compounds is a secondary amine, the amine-epoxy reaction can be conducted first, followed by addition of the organic acid to form the 5 salt and thus produce the cationic form of the resin. Larger excesses of amine can be used and the excess amine subsequently removed as known in the art such as by vacuum distillation, steam distillation, falling film 0 distillation. For the onium-forming reactions, the amount of water that is also included in the reaction mixture can be varied to convenience so long as there is sufficient acid and water present to stabilize the cationic salt formed during the course of the reaction. Normally, it has been found preferable to include water in the reaction in amounts of from 5 to 30 moles per epoxy equivalent. When the nucleophilic compound is a secondary amine, the water can be added before, during, or after the resin epoxy group/nucleophile reaction. The preferred range of charge density of the cationic, advanced epoxy resin is from 0.2 to 0.8 milliequivalent of charge per gram of the resin, calculated assuming complete salting of the limited reagent (acid or amine). 10 It has also been found advantageous to include minor amounts of water-compatible organic solvents in the reaction mixture. The presence of such solvents tends to facilitate contact of the reactants and thereby - c promote the reaction rate. In this sense, this particular reaction is not unlike many other chemical reactions and the use of such solvent modifiers is conventional. The skilled artisan will, therefore, be aware of which organic solvents can be included. 0 When a desired degree of reaction is reached, any excess nucleophilic compound can be removed by standard methods, e.g., dialysis, vacuum stripping and steam distillation. 25 The cationic, advanced epoxy resins of this invention in the form of aqueous dispersions are useful as coating compositions, especially when applied by electrodeposition. The coating compositions containing 30 the cationic resins of this invention as the sole resinous component are useful but it is preferred to include crosslinking agents in the coating composition so that the coated films, when cured at elevated temperatures, will be crosslinked and exhibit improved film properties. The most useful sites on the resin for crosslinking reactions are the secondary hydroxyl groups along the resin backbone. Materials suitable for use as crosslinking agents are those known to react with hydroxyl groups and include blocked polyisocyanates; amine-aldehyde resins such as melamine-formaldehyde, urea- ormaldehyde, benzoguanine-formaldehyde, and their alkylated analogs; polyester resins; and phenol-aldehyde resins. The advanced resins of the present invention can be cured by any suitable curing agent for curing epoxy resins, e.g. those resins containing a vicinal epoxide group as well as those curing agents which cure through the secondary hydroxyl groups appearing along the backbone of either the epoxy terminated resins and the hydroxyl terminated resins. Suitable curing agents which cure through the epoxide groups include, compounds containing at least two primary or secondary amine hydrogen atoms such as, for example primary and secondary aliphatic, cycloaliphatic or aromatic amine compounds; compounds containing at least two carboxylic acid groups per molecule (organic polybasic acids) and their anhydrides such as for example, saturated an unsaturated aliphatic or cycloaliphatic carboxylic acids and aromatic carboxylic acids. Suitable primary or secondary amine-containing compounds which can be employed as the epoxy curing agent include, for example, ethylenediamine, diethylenetriamine, triethylenetetramine, tetraethylenepentamine, isophoronediamine, N- aminoethylpiperazine, menthanediamine, 1,3- diaminocyclohexane, xylylenediamine,. m-phenylenediamine, 1,4-methylenedianiline, metaphenylenediamine, diaminodiphenylsulfone, diaminodiphenyl ether, 2,4- toluenediamine, 2,6-diaminopyridine, bis(3, - diaminophenyDsulfone, resins prepared from aniline and formaldehyde, aminated polyglycols, any combination of any two or more such curing agents. Organic polybasic acid curing agents include, 10 for example, oxalic.acid, phthalic acid, maleic acid, aconitic acid, carboxyl terminated polyesters, any combination of any two or more such curing agents. Anhydrides of polycarboxylic acids include, for 15 example, phthalic anhydride, succinic anhydride, citraconic anhydride, itaconic anhydride, dodecenylsuccinic anhydride, Nadic Methyl Anhydride (methylbicyclo(2.2.1)heptene-2,3-dicarboxylic anhydride isomers), pyromellitic dianhydride, 20 cyclopentanetetracarboxylic dianhydride, benzophenonetetracarboxylic dianhydride,any combination thereof. pr - Other curing agents include, for example, amides and polyamides, urea-aldehyde resins, melamine- aldehyde resins., hexamethoxymethylmelamine, imidazoles, guanimines, aromatic hydroxyl-containing compounds, any combination thereof. Preferred other 30 curing agents which can be employed herein include, for example, dicyandiamide, 2-methylimidazole, phenol- formaldehyde resins, cresol-formaldehyde resins, any combination thereof. Curing agents which cure through the secondary hydroxyl groups along the backbone of the advanced resins include, for example, polyisocyanates, blocked polyisocyanates, urea-aldehyde resins, melamine-aldehyde resins, phenol-aldehyde novolac resins, alkylated phenol-aldehyde novolac resins, any combination thereof. Preferred such curing agents include, for example, hexamethoxymethylmelamine, urea-formaldehyde resins, melamine-formaldehyde resins, aromatic or cycloaliphatic or aliphatic polyisocyanates, blocked polyisocyanates, a mixture of the allyl ethers of mono-, di- and tri- methylol phenol, a mixture of the allyl ethers of methylol phenol partially polymerized, phenol- formaldehyde novolac resins and cresol-formaldehyde novolac resins, any combination thereof. Blocked polyisocyanates include, for example, those blocked with alcohols, phenols, oximes, lactams and N,N-dialkylamides or esters of alpha-hydroxyl group- containing carboxylic acids. Particularly suitable polyisocyanates include, for example, isocyanurate trimer of hexamethylene diisocyanate, toluene diisocyanate, methylene diphenylene diisocyanate, isophorone diisocyanate, a prepolymer of toluene diisocyanate and trimethylolpropane.

The preferred ketoximes is methyl ethyl ketoxime, acetone oxime, methyl ethyl ketoxime, methyl amyl ketoxime, methyl isobutyl ketoxime, cyclohexanone ketoxime. The blocked polyisocyanates are prepared by reacting equivalent amounts of the isocyanate and the blocking agent in an inert atmosphere such as nitrogen at temperatures between 25° to 100°C, preferably below 70°C to control the exothermic reaction. Sufficient blocking agent is used so that the product contains no residual, free isocyanate groups. A solvent compatible with the reactants, product, and the coating composition can be used such as a ketone or an ester. A catalyst can also be employed such as dibutyl tin dilaurate. The blocked polyisocyanate crosslinking agents are incorporated into the coating composition at levels corresponding to from 0.2 to 2.0 blocked isocyanate groups per hydroxyl group of the cationic resin. The preferred level is from 0.3 to 1 blocked isocyanate group per resin hydroxyl group. A catalyst can, optionally, be included in the coating composition to provide faster or more complete curing of the coating. Suitable catalysts for the various classes of crosslinking agents are known to those skilled in the art. For the coating compositions using the blocked polyisocyanates as crosslinking agents, suitable catalysts include dibutyl tin dilaurate, dibutyl tin diacetate, dibutyl tin oxide, stannous octanoate, and other urethane-forming catalysts known in the art. Amounts used typically range between 0.1 and 3 weight percent of binder solids. The curing agents are employed in amounts which will generally cure the advanced resin, i.e. that amount which is sufficient to render the resultant cured coating composition non-tacky. In those instances where the curing agent cures by reacting with the epoxide groups, they are employed in amounts which provide a ratio of equivalents of curing agent per epoxide group of from 0.01:1 to 10:1, preferably from 0.1:1 to 5:1, more preferably from 0.5:1 to 1.5:1. In those instances where the advanced resin cures through the secondary hydroxyl groups along the backbone, the curing agent is employed in amounts which provide a ratio of equivalents of curing agent per secondary hydroxyl group of from 0.05:1 to 5:1, preferably from 0.1:1 to 3:1, more preferably from 0.3:1 to 2:1. 10 The advanced resins of the present invention can be blended with other materials such as solvents or diluents, fillers, pigments, dyes, flow modifiers, thickeners, reinforcing agents, antifoam agents, slip agents, adhesion promoters, flexibility promoters, 15 surface tension modifiers, stress release agents, gloss reducing agents, rheology modifiers, stabilizers, surfactants, plasticizers, or any combination thereof. The amount of additive depends on the 20 additive type, formulation, crosslinker (curing agent) concentration and type, and many other variables. As a consequence, the Applicants do not wish to be bound by any particular concentration pc - range. Typically additives are usually employed in amounts of from 0.00001 to 10, preferably from 0.001 to 5, more preferably from 0.01 to 0.05 percent by weight based upon the weight of total solids. 30 Fillers are added in amounts up to 60 percent by weight. Plasticizers are added in quantities of from10 to 40 percent by weight. Solvents or diluents which can be employed herein include, for example, alcohols, hydrocarbons, ketones, glycol ethers, or any combination thereof. Particularly suitable solvents or diluents include, for example, methanol, ethanol, isopropanol, butanol, pentanol, toluene, benzene, xylene, methyl ethyl ketone, methyl isobutyl ketone, diethylene glycol methyl ether, dipropylene glycol methyl ether, ethylene glycol methyl ether, ethylene glycol ethyl ether, ethylene glycol butyl ether, ethylene glycol phenyl ether, or any combination thereof. Reinforcing materials which can be employed herein include natural and synthetic fibers in the j. form of woven cloth , mat, monofilament, multifilament. Suitable reinforcing materials include, glass, ceramics, nylon, rayon, cotton, aramid, graphite, or any combination thereof. 0 Suitable fillers which can be employed herein include, for example, inorganic oxides, ceramic microspheres, plastic microspheres, or any combination thereof. _- The advanced resins of the present invention are particularly useful in the preparation of coatings; however, they ifiay also find utility in castings, laminates, encapsulants. 0 The coating compositions can be applied by any conventional method known in the coating industry. Therefore, spraying, rolling, dipping, flow control or electrodeposition applications can be employed for both clear and pigmented films. Spraying is the preferred technique for the aqueous .coating compositions. After application onto the substrate, the coating is thermally cured at temperatures of from 95°C to 280°C or higher, for periods in the range of from 0.08 to 60 minutes-. The resultant films can be dried at ambient temperatures for longer periods of time. Unpigmented coating compositions are prepared by blending the resinous product with the crosslinking agent and optionally any additives such as catalysts, solvents, surfactants, flow modifiers, plasticizers, defoamers, or other additives. This mixture is then dispersed in water by any of the known methods. A preferred method is the technique known as phase- inversion emulsification, wherein water is slowly added with agitation to the above mixture, usually at temperatures ranging from ambient to 70°C, until the phases invert to form an organic phase-in-water disper¬ sion. The solids content of the aqueous dispersion is usually between 5 and 45 percent by weight and preferably between 10 and 30 percent by weight for application by electrodeposition. Pigmented coating compositions are prepared by adding a concentrated dispersion of pigments and extenders to the unpigmented coating compositions. This pigment dispersion is prepared by grinding the pigments together with a suitable pigment grinding vehicle in a suitable mill as known in the art. Pigments and extenders known in the art are suitable for use in these coatings including pigments which increase the corrosion resistance of the coatings. Examples of useful pigments or extenders include titanium dioxide, talc, clay, lead oxide, lead silicates, lead chromates, carbon black, strontium chromate, and barium sulfate. Pigment grinding vehicles are known in the art. A pigment grinding vehicle suitable for use with electrodepositable coatings consists of a water-soluble cationic resinous product, water, and a minor amount of water-compatible solvent. The cationic resinous product is prepared by reacting an epichlorohydrin/bisphenol A condensation product having an epoxide group content of 8 percent with a nucleophilic compound, an acid, and water in a similar fashion as described above for the cationic resins used in the preferred embodiment of the invention. The water-soluble product can be diluted with water to form a clear solution useful as a pigment grinding vehicle. The pH and/or conductivity of the coating compositions can be adjusted to desired levels by the addition of compatible acids, bases, and/or electrolytes known in the art. Other additives such as solvents, surfactants, defoamers, anti-oxidants, bactericides, etc. can also be added to modify or optimize properties of the compositions or the coating in accordance with practices known to those skilled in the art. Although the coating compositions of the invention can be applied by any conventional technique for aqueous coatings, they are particularly useful for application by cathodic electrodeposition, wherein the article to be coated is immersed in the coating com¬ position and made the cathode, with a suitable anode in contact with the coating composition. When sufficient voltage is applied, a film of the coating deposits on the cathode and adheres. Voltage can range from 10 to 1,000 volts, typically 50 to 500. The film thickness achieved generally increases with increasing voltage. In the case of the coating compositions of the invention, suitable films may be achieved at higher voltages than for compositions using resins prepared by a one-step preparation. Current is allowed- to flow for between a few seconds to several minutes, typically two minutes over which time the current usually decreases. Any electrically conductive substrate can be coated in this fashion, especially metals such as steel and aluminum. Other aspects of the electrodeposition process, such as bath maintenance, are conventional. After deposition, the article is removed from the bath and typically rinsed with water to remove that coating composition which does not adhere. The uncured coating film on the article is cured by heating at elevated temperatures, ranging from 200°F to 536°F (93°C to 280°C), for periods of 0.08 to 60 minutes. EXAMPLE 1 RECRYSTALLIZATION OF 1,2-BIS(3- HYDROXYPHENOXY)ETHANE Technical grade (85 percent purity) of 1,2-Bis- (3-hydroxyphenoxy)ethane, 3,3'-ethylenedioxydiphenol, was obtained from Aldrich Chemical Chemical Company. A 300 gram sample was dissolved in 750 ml of acetone which was then treated with decolorizing carbon and filtered through a filter aid, celite, to remove particulate matter and colored impurities. The filtrate was concentrated to 600 ml by distillation at atmospheric 10 pressure and allowed to stand at room temperature overnight. A crystalline material, 29 grams, .was removed by filtration under reduced pressure and enough acetone was added to the filtrate to bring the volume up -.c to 800 ml. After cooling in the refrigerator overnight, another 115 grams of white crystalline material was recovered and high pressure liquid chromtography (HPLC) analysis revealed 95 percent purity by peak area. This 115 gram fraction was redissolved in acetone to a volume 0 of 300 ml and, after cooling in a refrigerator overnight, a 91.6 gram fraction of white crystalline material (97.3 area percent purity by HPLC analysis) was recovered for use in examples 8, 9, 17, and 21. Both 1H and 13C nuclear magnetic resonance (NMR) spectra were 25 consistent with the known structure. EXAMPLE 2 PREPARATION OF 1,4-BIS(3- HYDR0XYPHEN0XY)BUTANE A five neck five liter round bottom flask 30 equipped with a mechanical stirrer, two condensers, and a dropping funnel was purged with nitrogen then charged under a nitrogen blanket with 1.5 kg (13.6 moles) resorcinol, 120 grams deionized water, and 138.75 grams (0.64 moles) 1 ,4-dibromobutane. The reaction slurry was slowly heated with stirring to reflux under a slow nitrogen purge; then a solution of 109 grams (1.64 moles) 85 percent KOH pellets in 109 grams water was added dropwise under a nitrogen blanket over a two hour period. After an additional hour of refluxing, the reaction mixture was allowed to cool enough to pour the contents into 10 liters deionized water. The water slurry was acidified with 30 percent sulfuric acid and allowed to stand at room temperature overnight before filtering under reduced pressure and washing with several portions of warm water. The residue, 80 grams of yellow amorphous solid, was then extracted with large quantities of boiling water to remove oils. After cooling to room temperature, the water extracts (14 liters) yield 28 grams of white, shiny platelets. HPLC analysis revealed 92 percent purity by peak area. Recrystallization from acetone yielded product of >98 percent purity by HPLC analysis with a melting point of 103°C-106°C (literature melting point, 105°C-108°C) for use in examples 10, 18 and 20. Both 1H and 13C NMR spectra were consistent with the proposed structure. EXAMPLE 3 PREPARATION OF 1,4-BIS(4- HYDR0XYPHEN0XY)BUTANE A five neck five liter round bottom flask equipped with a mechanical stirrer, two condensers, and a dropping funnel was purged with nitrogen then charged under a nitrogen blanket with 1.25 kg (11.36 moles) hydroquinone,. 350 grams deionized water, and 231.25 grams (1.07 moles) 1 ,4-dibromobutane. The reaction mass becomes a stirable slurry as it was slowly heated to reflux under a slow nitrogen purge. A solution of 180 grams (2.7 moles) 85 percent KOH pellets in 180 grams water was added dropwise under a nitrogen blanket over a two hour period. After about one third of the KOH had been added, the slurry had converted to a tea colored solution; then, after most of the KOH had been added, a white material precipitates in increasing amounts as the refluxing was continued an additional hour. The reaction mixture was quenched before cooling by pouring into 6 liters deionized water. The water slurry was acidified with 30 percent sulfuric acid and allowed to stand at room temperature overnight before filtering under reduced pressure and washing with several portions of boiling water to remove hydroquinone. The white, residue was dried in a vacuum oven at 140°C to a weight of 240 grams. It was then taken up in 4 liters boiling MEK, treated with decolorizing carbon and filtered through a filter aid, celite, to remove particulates and colored impurities. A total of 154 grams of a white product was recovered from a series of filtrates. Analysis by gpc showed contamination by higher molecular weight species which were much less soluble in acetone than the desired product; thus, the product was taken up in boiling acetone, filtered, and cooled to recover 135 grams (46 percent yield based on the dibromobutane). HPLC analysis showed >90 percent purity by peak area. Another crystallization from 3 liters boiling acetone yields 116 grams of white "mica-like" crystals (melting point 202°C-204°C) with greater than 96 percent purity by HPLC peak area" or use in examples 11 and 22. Both 1H and 13C NMR spectra were consistent with the proposed structure. EXAMPLE 4 PREPARATION OF 1,8-BIS(4- HYDR0XYPHEN0X )OCTANE A five neck five liter round bottom flask equipped with a mechanical stirrer, two condensers, and a dropping funnel was purged with nitrogen then charged under a nitrogen blanket with 1.1 kg (10.0 moles) hydroquinone, 350 grams deionized water, and 272.0 grams (1.0 moles) 1,8-dibromooctane. The reaction mass becomes a stirable slurry as it was slowly heated to reflux under a slow nitrogen purge. A solution of 184 grams (2.7 moles) 85 percent KOH pellets in 184 grams water was added dropwise under a nitrogen blanket over a period of 75 minutes. After about one third of the KOH had been added, the slurry had converted to a tea 10 colored solution; then, after.most of the KOH had been added, a white material precipitates in increasing amounts as the refluxing was continued an additional 90 minutes. The reaction mixture was quenched with one liter of water then poured into 4 liters of water. The 15 water slurry was acidified with 30 percent sulfuric acid and filtered under reduced pressure. The filter cake was slurried in warm (50-70°C) water, filtered again and washed with several portions of boiling water. It was then dried in a vacuum oven at 120°C and 310 grams of 20 crude white product was recovered. The product was treated with 8 liters of boiling ethanol and filtered to remove oligomers. The filtrate yields a total of 134 grams (41 percent Yield based on the dibromide) of p c - white, shiny, "mica-like" crystals more than 95 percent pure by HPLC peak area and GPC analysis. A final crystallization" from 1.1 liters boiling ethanol gives product more than 99 percent pure by HPLC peak area (m.p. 151- 153-5°C) for use in preparation of the 30 copolymer epoxy resin, examples 12, 14, 15, 23 and 24. The ultraviolet absorption spectrum in 30/70 (by volume) methanol/dimethylformamide (DMF) showed a maximum absorption at 297 πm and in 30/70 (by volume) 1.0N KOH in methanol/DMF at 315 nm. EXAMPLE 5 PREPARATION OF 1,8-BIS(3- HYDROXYPHENOXY)OCTANE A five neck five liter round bottom flask equipped with a mechanical stirrer, two condensers, and a dropping funnel was purged with nitrogen then charged under a nitrogen blanket with 1.6 kg (14.5 moles) resorcinol, 160 grams deionized water, and 296.7 grams (1.091 moles) 1,8-dibromooctane. The easily stirable reaction mass was slowly heated to reflux under a slow nitrogen purge. A solution of 181 grams (2.74 moles) 85 percent KOH pellets in 184 grams water was added dropwise at reflux under a nitrogen blanket over a period of two hours. After about 25 percent of the KOH had been added, the reaction mass had dissolved to light tea colored solution then it becomes increasingly clouded as salt was formed. The reaction mixture was refluxed an additional hour after all the KOH had been added. The pH of the reaction mixture was basic. The reaction was quenched with 1.5 liters of water and acidified with 40 percent sulfuric acid. The reaction mixture was then poured into 4 liters of water, cooled in an ice bath to a temperature of 10°C and filtered to recover a tan colored solid which was slurried in 1.2 liters boiling water to wash out resorcinol and KBr. The cooled slurry was then filtered and 350 grams of crude product was recovered. Crystallization from 400 ml acetone yield 170 grams white crystals, '88 percent pure by HPLC peak area, and recrystallization from 500 ml acetone yields 97-4 grams product of 96 percent purity by HPLC peak area and high purity by gel permeation chromatography (m.p. 78-82°C). EXAMPLE 6 PREPARATION OF THE DIGLYCIDYL ETHER OF 1,8- BIS(4-HYDROXYPHENOXY)OCTANE A one liter, five neck flask equipped with a Truebore Vacuum stirrer, a Dean Stark trap designed to replenish the flask with the more dense layer of propylene glycol methyl ether in epichlorohydrin while retaining the less dense layer of water, a glycol cooled condenser, a thermometer, and a dip tube for adding caustic solution fed by a peristaltic pump was charged with 574.4 grams of .a 20 wt. percent solution of propylene glycol methyl ether in epichlorohydrin (4.98 moles epichlorohydrin) and 111.02 grams (0.336. moles) of 1,8-Bis(4-hydroxyphenoxy)octane from example 4. The Dean Stark trap was filled with a 20 wt. percent solution of propylene glycol methyl ether in epichlorohydrin, the system was purged with nitrogen and the reaction mixture was heated to reflux (65°C at 170 mm Hg pressure controlled by a I2R Manostat with nitrogen bleed). Analysis by ultraviolet spectroscopy (UV) of a sample of the reaction slurry taken at this point showed 15.3 wt percent diphenol (compared to 16.2 wt. percent based on amounts charged). 53.76 grams of 50 percent aqueous caustic (0.672 moles of NaOH) was added through the dip tube at a constant rate over a one hour period at reflux (65°C at 170 mm Hg pressure). After about 25 percent of the caustic had been added, the reaction mixture dissolves into a dark purple solution then .it becomes increasingly clouded as NaBr was produced. Increasing amounts of water was collected in the Dean Stark trap. A sample taken near the end of caustic addition was neutral to pH test paper and showed 95 percent conversion of the starting diphenol. The remaining caustic along with a 5-10 percent excess was added over a twenty minute period and refluxing was continued another 15 minutes. The reaction mixture at this point was basic to pH test paper and it showed better than 99.8 percent conversion of the starting diphenol by UV analysis. The heating mantle was removed and the reaction was quenched by acidifying with C0 chips. A 300 ml portion of methylene chloride was added to the cooled, viscous reaction mass to allow filtration under reduced pressure. The filter pad was then taken up in 3.5 liters of warm methylene chloride and filtered to remove salt and insoluble materials. The methylene chloride solution was washed with three portions of 300 ml each of distilled water and was then passed through 2V filter paper twice to remove most of the resorcinol and NaBr. The clear solution was concentrated under reduced pressure and was allowed to crystallize. The white crystals (108.8 grams, m.p. 120-122°C) were better than 99 percent pure by HPLC peak area and titration revealed 18.1 percent epoxide (theoretical, 19.4 percent) . EXAMPLE 7 PREPARATION OF THE DIGLYCIDYL ETHER OF 1,8- BIS(3-HYDROXYPHENOXY)OCTANE A one liter, five neck flask equipped with a Truebore Vacuum stirrer, a Dean Stark trap designed to replenish the flask with the more dense layer of propylene glycαJ. methyl ether in epichlorohydrin while retaining the less dense layer of water, a glycol cooled condenser, a thermometer, and a dip tube for adding caustic solution fed by a peristaltic pump was charged with 574.4 grams of a 20 wt. percent solution of propylene glycol methyl ether in epichlorohydrin (4.98 moles epichlorohydrin) and 111.02 grams (0.336 moles) of 1 ,8-Bis(3-hydroxyphenoxy)octane from example 5. The Dean Stark trap was filled with a 20 wt. percent solution of propylene glycol methyl ether in epichlorohydrin, the system was purged with nitrogen and the reaction mixture was heated to reflux (65°C at 180 mm Hg pressure controlled by a I2R Manostat with nitrogen bleed). Then 56 grams of 50 percent aqueous caustic (0.70 moles of NaOH) was added to the light yellow reaction solution through the dip tube at a constant rate over a one hour period at reflux (65°C at 170 mm Hg pressure). The solution darkens during 10 caustic addition and becomes increasingly clouded as NaBr was produced. Reflux was continued an additional 30 minutes after caustic addition was completed. A sample tests neutral to pH test paper and showed better than 99.^ percent conversion of the starting diphenol by 15 UV analysis.

An aqueous dispersion was prepared by combining 280 grams of the above resin solution, 167.2 grams of 0 Crosslinker A, 13-2g of propylene glycol phenyl ether, 4.3g of Surfactant A, and 13.0 grams of lactic acid (73.5 percent non-volatile) in a suitable reaction vessel. The mixture was stirred very rapidly as 553 grams of D.I. water was added dropwise over a period of 5 90 minutes. The resulting aqueous dispersion was then stripped of methyl isobutyl ketone solvent to yield a dispersion of about 32 percent solids. The dispersion was then pigmented with a 0 commercial ED-4 pigment paste to a pigment/binder ratio of 0.25. The final bath had a non-volatile content of 20 percent. c - The results are given in Table VII. EXAMPLE 69 Into a 1 liter round bottom flask equipped with a condenser, thermometer, nitrogen inlet, and a 0 mechanical stirrer was charged 100.4 grams (.053 equiv) of the diglycidyl ether of bisphenol A having an EEW of 188.7, and 150.1 grams (0.81 equiv) of the diglycidyl ether of 1 ,2-bis(3-hydroxyphenoxy)ethane prepared as in Example 8 having an EEW of 185.5, and 124.7 grams (1 equiv) of 1 ,2-bis(3-hydroxyphenoxy)ethane prepared as in Example 1. The mixture was heated to 110C and 0.3 grams of a 70 percent solution of ethyltriphenyl phosphonium phosphate in methanol was added as a catalyst. The mixture was heated to 160°C and allowed to exotherm. The temperature was then maintained between 165 and 170°C for 30 minutes. The epoxide equivalent weight was measured at 1181. The mixture was then cooled to 120°C and 136.2 grams of methyl isobutyl ketone was added. At 90°C, 33.3 grams of 2- (methylamino)ethanol was added and allowed to react, with the epoxy for 60 minutes at a temperature between 90 and 95°C. The solution was then cooled to room temperature and the non-volatile content was measured at 75.4 percent. An aqueous dispersion was prepared by combining 280 grams of the above resin solution, 165.9g of Crosslinker A, 13.1g of propylene glycol phenyl ether, 4.2g of Surfactant A, and 12.2g of lactic acid (73.5 percent non-volatile) in a suitable reaction vessel. The mixture was stirred very rapidly as 547g of D.I. water was added dropwise over a period of 90 minutes. The resulting aqueous dispersion was then stripped of methyl isobutyl ketone solvent to yield a dispersion of about 32 percent solids. The dispersion was then pigmented with a commercial ED-4 pigment paste to a pigment/binder ratio of' 0.25/1. The final bath had a non-volatile content of 20 percent. The results are given in Table VII. a Determined by DSC . TEST PROCEDURES EPOXIDE EQUIVALENT WEIGHT (EEW) The epoxide equivalent weight was determined by titration with perchloric acid and tetramethyl ammonium bromide by the procedure of ASTM D-1652-87. GLASS TRANSITION TEMPERATURE (Tg) The glass transition temperature of the resins were determined on a DuPont 912 Differential Scanning Calorimeter (DSC). The glass transition temperature of the cured coatings was determined on a DuPont 943 Thermomechanical Analyzer (TMA). The glass transition temperature of the cured coatings prepared in Examples 66-69 and comparative experiments S and R were determined by differential scanning calorimetry (DSC). MOLECULAR WEIGHT Molecular weight was determined by Gel Permeation Chromatography (GPC) on a Waters model 150-C Gel Permeation Chromatograph equipped with a Bimodal Column Set using tetrahydrofuran eluant at 1 cc/min. calibrated against polystyrene standards. WEDGE BEND 0 Wedge bend was determined according to a modified ASTM D3281-84 procedure, where the diameter of the bend at the less stressed end was either 1/8 inch (3.175 mm) or 1/16 inch (1.5875 mm). The bend was taped £ - and pulled with Scotch brand 610 tape and treated with acidic copper sulfate solution to highlight the exposed metal. The results are reported as millimeters of coating failure. 0 METHYL ETHYL KETONE (MEK) RESISTANCE The resistance of the cured coating on a cold rolled steel panel to removal with methyl ethyl ketone was determined by rubbing across the baked panels a two t - pound ball pein hammer with the ball end covered with eight layers of cheesecloth which had been saturated with methyl ethyl ketone (MEK). No force was applied to the hammer other than that necessary to guide the hammer back and forth over the same area. A twelve inch ruler 0 clamped into place was used to guide the hammer in the same path. The coated panels after rubbed were dipped into a mixture of 20 percent CuS04 5H20 and 10 percent concentrated hydrochloric acid in water for 30 seconds and then dipped into deionized water to determine breakthrough. A forward and reverse stroke returning to the starting point was considered as being one MEK double rub. T-BEND T-bend was used as a measure of the flexibility of the coating on the panel at a slow rate of deformation. The edges of the cold rolled steel panel were cut to leave a two inch wide specimen of uniform thickness. A bend was made in the panel at approximately 0.75 inches from the end of the coated panel by using a fingerbrake. The bend was squeezed tight with the palm of the hand. Then the bent specimen was placed in a vice, which was previously taped with plastic tape to prevent scratching the substrate, and the panel was bent back on itself to form a 180 degree bend. The stressed area was then tested for adhesion by taping with Scotch 610 tape. The tape was applied in such a manner where no air bubbles were trapped under the tape. The tape was then pulled with a rapid and forceful fashion at a 90 degree angle in an attempt to pull the coating away from the substrate ' . Next the bend was dipped into a solution of copper sulfate (10 grams) in 1.0 N hydrochloric acid for 30 seconds and then dipped into deionized water. The purpose of this step was to oxidize any resulting bare metal in order to more accurately observe adhesion failures. The specimen was examined under a magnifying glass to determine failure. The first bend was noted as TO (T zero) because there was no panel sandwiched between the bend. The process of bending the panel by using the fingerbrake and vice was continued until there was no sign of cracking or adhesion loss. Each successive bend was noted as T1, T2, T3, T4, etc. because of the number of layers of panel sandwiched between plys. The lower the number of T-bends, the better the flexibility. IMPACT RESISTANCE Impact resistance was a measure of the formability of a coating on a panel at a rapid rate of deformation. Coated cold rolled steel panels were subjected to the impact of a falling weight from a Gardner Impact Tester at different calibrated heights ranging from 0 to 160 inch-pounds. The impacted area was then tested for adhesion by taping with Scotch 610 tape. The tape was applied in such a manner that no air bubbles were trapped under the tape. The tape was then pulled with a rapid and forceful fashion at a 90 degree angle in an attempt to pull the coating away from the substrate. Next, a solution of copper sulfate (10 grams) in 1.0N hydrochloric acid (90 grams) was applied to the impacted area to check for failure. The specimen was examined under a table-top illuminated magnification system with lenses having a total of 11 diopter power to determine failure. WATER PASTEURIZATION RESISTANCE Water pasteurization resistance was performed on a single specimen for each coating to determine the permeability of the coating to water with pressure and heat. The coating substrate was tin free steel. The width of each specimen was about 12 centimeters while the length was about 6 centimeters. A mold and the Gardner Impacter Tester were used to form a semi¬ circular bend in each specimen. The semi-circular bend was used to simulate a stressed area. The dart impacter rod was dropped from 56 inch-pounds for all the specimens when forming the bend. The specimens were then placed in a Model 8100-TD NORCO Autoclave with deionized water for 90 minutes at 121°C (250°F) and 1 bar (15 psi) pressure. The clock was only started after both the desired temperature and pressure were reached. After the specimens were pasteurized for the prescribed conditions, the heat was turned off, the pressure bled off and the panels removed for testing. The coated 10 specimens were submerged in deionized water after removal from the autoclave. The specimens were blotted dry after removal from the water with a paper towel. They were rated for blush and adhesion. _,_ The tested coatings were rated for blush by placing the specimens next to the panels from which the specimens were cut. The coatings were rated for blush according to the following scale: 0 5 0 Adhesion was determined by using the tape test described in method A of ASTM 3359-87. The tape was Scotch 610 tape. X-cuts were made in the stressed and non-stressed areas of each specimen. The adhesion of the non-stressed specimen was listed first while the adhesion in the stressed area was listed second. The coatings were listed for adhesion according to the following scale. WET AND DRY ADHESION The coatings were tested for wet and dry. adhesion under wet and dry conditions, using the T-peel test ASTM D1876 (1978). A wet adhesion test was performed on test panels by first immersing the test panels in 90 C C water for four days and then carrying out the T-peel test. A dry adhesion test was carried out on test panels without immersing the test panels in 90°C water. THROWPOWER Two 18" x 4" (45.72 cm x 10.16 cm) phosphated panels were assembled face-to-face and parallel with a 3/8" (9.5 mm) space between them using a slotted rubber strip down each side. Only the bottom of the assembly was open for paint and current. The coatings were electrodeposited for two minutes at 275 volts at 8θ°F (26.7°C). A linear measurement of how high the coating plated on the inside of the assembly was referred, to as throw, the results being indicated in the tables as throwpower. CHIP RESISTANCE The Chip Resistance was determined by the procedure of ASTM D3170-87 and the results were quantified using a Que-2 Image analyzer. The number recorded represnts the number of chips in an 80 cm2 area multiplied by the average area of each chip. The smaller the number, the better the chip resistance. GM SCAB CORROSION TEST This test was a cyclic test where the panels were scribed and subjected to 20 corrosion cycles. One cycle consists of a 24 hour period which the panels were 10 immersed in ambient temperature 5 percent salt solution for 15 minutes followed by a room temperature drying period for one hour and 15 minutes and then placed in a humidity cabinet (60°C and 85 percent relative humidity) for 22 hours and 30 minutes. During cycles 1, 6, 11 and 15 16, the panels were additionally exposed to hot and cold by placing them in an oven at 60°C for 1 hour followed by a freezer at -10°F (-23.9°C) for 30 minutes. During these cycles, the total time the panels were in the humidity cabinet was 22 hours and 30 minutes. After 20 20 cycles, the panels were scraped to remove any loose coatings. Then the width of the scribe was measured in millimeters at ten different positions. The results are reported as the average width of the total creep. A pt - lower number represents better corrosion resistance. 30
