<p><P>PROBLEM TO BE SOLVED: To provide an electrodeposition coating composition capable of forming a transparent film to form a coating film imparting transparency, having appearance excellent in metallic luster and excellent in electrodeposition uniformity even at an edge part, and compatibilizing excellent abrasion resistance and adhesiveness required in an exterior coating of an electronic device to be used in an adverse environment; a water-base electrodeposition coating material; an electrodeposition coating method; and an electrodeposition coated product. <P>SOLUTION: Electrodeposition coating is performed by using the water-base electrodeposition coating material obtained by adding an amine-based neutralizing agent to the electrodeposition coating composition containing 30-80 wt.% of a (meth)acrylic resin (A) polymerized in a solvent containing an aprotic polar solvent and having anionic electrodeposition property and a weight-average molecular weight of 1,000-40,000, 10-60 wt.% of an amino resin (B) and 0.1-30 wt.% of inorganic fine particles having an average particle diameter of 0.01-5μm, and dispersing the composition in water. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
