Method of electrodeposition using an electrocoating composition containing a low volatile organic content pigment grind composition

A method of electrocoating an electroconductive substrate serving as a charged electrode in an electrical circuit comprising said electrode and an oppositely charged counter electrode, at least one of said electrodes being immersed in an aqueous electrocoating composition, comprising passing electric current between said electrodes to cause the deposition of the electrocoating composition on the substrate as a substantially continuous film and drying or heating the electrodeposited film at elevated temperatures to form an at least partially cured film, said aqueous electrocoating composition comprising

• (a) an electrodepositable water dispersible film forming polymer,
• (b) a pigment grind composition having a volatile organic content (VOC) of less than 1 pound per gallon comprising a pigment, an electrodepositable water-dispersible acrylic polymer, and a reactive diluent having a number average molecular weight of between about 200 and about 2500 selected from the group consisting of polyalkylene glycol mono esters formed by the reaction of polyalkylene glycol with a monocarboxylic acid having between eight and eighteen carbon atoms glycol ether formals, and mixtures thereof.
