Electrodeposition liquid and electrodeposition-coated article

An electrodeposition dispersion comprising:

• a polyamide-imide resin;
• a polar solvent;
• water;
• a poor solvent having a solubility of polyamide-imides of 1 g/100 g-the solvent or less;
• and
• a base,
• wherein the polar solvent is an organic solvent having a boiling point of higher than 100° C. and D(S-P) represented by a formula (1) satisfying a relationship of D(S-P)<6, where D(S-P) represents a Hansen solubility parameter value (HSP value),
• a weight-average molecular weight of the polyamide-imide resin is 10×104 to 30×104 or a number-average molecular weight of the polyamide-imide resin is 2×104 to 5×104,
• an average size of the polyamide-imide resin particles is 400 nm or less,
• D(S-P)=[(dDS−dDP)2+(dPS−dPP)2+(dHS−dHP)2]1/2 (1)
• where dDS represents a dispersion term of an HSP value of the polar solvent, dDP represents a dispersion term of an HSP value of the polyamide-imide resin, dPS represents a polarity term of the HSP value of the polar solvent, dPP represents a polarity term of the HSP value of the polyamide-imide resin, dHS represents a hydrogen bonding term of the HSP value of the polar solvent, and dHP represents a hydrogen bonding term of the HSP value of the polyamide-imide resin,
• the poor solvent is selected from the group consisting of isopropyl alcohol, 1-methoxy-2-propanol and cyclohexanone, and
• the average size of the polyamide-imide resin particles is in a range of 130 to 290 nm.
