What is claimed is: 1. An aqueous effect coating material comprising at least one water soluble or dispersible binder, at least one effect pigment, and a neutralized mixture of at least two fatty acids selected from the group consisting of fatty acids having 6 to 30 carbon atoms in the molecule, comprising from 1 to 6 percent by weight of the neutralized mixture of at least two fatty acids, based on the weight of the effect pigment, wherein an excess of neutralizing agent is employed for the neutralized mixture of at least two fatty acids and wherein the neutralizing agent is selected from the group consisting of ammonia, trimethylamine, triethylamine, tributylamine, amino alcohols, dibutylamine, dimethylaniline, diethylaniline, triphenylamine, dimethylethanolamine, diethylethyanolamine, methyldiethanolamine, 2-aminomethylpropanol, dimethylisopropylamine, dimethylisopropanolamine, triethanolamine, and combinations thereof. 2. The coating material as claimed in claim 1, wherein the at least one effect pigment comprises at least one metallic effect pigment. 3. The coating material as claimed in claim 1, wherein the at least one effect pigment comprises at least one aluminum effect pigment. 4. The coating material as claimed in claim 3, wherein the at least one aluminum effect pigment is selected from the group consisting of nonleafing pigments. 5. The coating material as claimed in claim 3, wherein the aluminum effect pigment or pigments are selected from the group consisting of aluminum effect pigments having a substantially circular form and aluminum effect pigments having a substantially elongate form. 6. The coating material as claimed in claim 3, wherein the at least one aluminum effect pigment is selected from the group consisting of leafing pigments. 7. The coating material as claimed in claim 1, wherein at least two fatty acids selected from the group consisting of caproic acid, enanthic acid, caprylic acid, pelargonic acid, capric acid, undecylic acid, lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, elaidic acid, arachidic acid, behenic acid, lignoceric acid, cerotic acid, and melissic acid are used. 8. The coating material as claimed in claim 1, wherein the water soluble or dispersible binder or binders are selected from the group consisting of polyurethanes, polyesters, and polyurethane modified (meth)acrylate copolymers. 9. A process for preparing a coaxing material as claimed in claim 1, which comprises (I) dispersing the effect pigment or pigments in a mixture comprising at least one water miscible organic solvent, at least one water soluble or dispersible binder, and the neutralized mixture of at least two fatty acids; (II) combining the resulting dispersion (I) with an aqueous solution or dispersion of at least one water soluble or dispersible binder. 10. A method of coating with a coating material as claimed in claim 1, comprising applying the coating material of claim 1 to a substrate selected from the group consisting of automotive substrates, interior and exterior constructions, doors, windows, furniture, industrial substrates, coil, containers, and electrical components. 11. The coating material as claimed in claim 1, wherein the neutralized mixture of at least two fatty acids comprises neutralized palmitic, stearic, and oleic acids.
