ていた。Prior art and conventional technology When forming a colored film on a metal object to be treated by electrodeposition coating, a method of obtaining a colored film using a solution containing a dye or pigment in an electrodeposition coating bath has been carried out. However, this method has various drawbacks, such as a tendency to cause unevenness in achromatization. Therefore, in order to solve this problem, after forming a clear electrodeposition coating on the metal object to be treated, the coating is immersed in a colored liquid containing dye or pigment, and then the coating is dried and hardened. Although a method of obtaining a colored film by using conventional methods has been proposed, the problem with this type of conventional method is that the dye used is limited to water-soluble dyes. In other words, conventionally, water-soluble dyes such as disperse dyes, basic dyes, and acid dyes have been used as coloring liquids for coloring clear electrodeposition coatings; It is excellent in terms of ease of use because it dissolves well, but on the other hand, because the dye is water-soluble, the colored coating does not necessarily have excellent physical properties such as water resistance, corrosion resistance, and chemical resistance. Also, the temperature resistance of the dye used is 1.
Since the temperature is 20 to 150°C or less, the temperature resistance is also not fully satisfactory. Therefore, there has been a strong demand for colored electrodeposition coatings that are water-resistant, corrosion-resistant, chemical-resistant, and temperature-resistant.

をなすに至ったものである。In other words, oil-soluble dyes have traditionally been mixed with various plastic particles;
It is used as a dye to dye plastics by heating, but since this dye is oil-soluble, it does not dissolve in water at all, so it cannot be used as a water-soluble coloring liquid, and it has not been used in the past. has not been used as a coloring dye for N-coated coatings, but a particularly hydrophilic organic solvent is used as a solubilizer, and an oil-soluble dye dissolved in this hydrophilic organic solvent is dissolved in water. The oil-soluble dye is dissolved in water at a significant concentration (sufficient concentration to color the e-coat film), and the e-coat film is immersed in this coloring liquid (either before baking or drying). after) by
The electrodeposited coating can be colored evenly and neatly, and the colored electrodeposition coating obtained has excellent water resistance, corrosion resistance,
It was discovered that it has chemical resistance and temperature resistance, and this led to the present invention.

、この有機溶剤が水と均一に混合するためである。When dissolving these oil-soluble dyes in water, a solubilizer is used.As a solubilizer, a hydrophilic organic solvent that dissolves these oil-soluble dyes and dissolves in water, such as ethylene glycol, ethanol, It is preferable to use one or more of isopropanol, cyclohexanone, methyl isobutyl ketone, ethyl acetate, butyl cellosolve, ethyl cellosolve, and the like. In this case, in order to dissolve the oil-soluble dyes of -F in water, it is preferable to first dissolve these dyes in a hydrophilic organic solvent and then mix this with water. Note that the oil-soluble dye is solubilized in water due to the action of the hydrophilic group of the hydrophilic organic solvent, and the organic solvent dissolves the oil-soluble dye and the organic solvent dissolves in water. This is to ensure uniform mixing.

との混合割合等を適宜選択し、着色液を作成する。When an oil-soluble dye is solubilized in water using a solubilizing agent (especially a hydrophilic solvent) to obtain a colored liquid, the degree of dye a is not necessarily limited, but is usually 1 to 52/no. ,
In particular, it is preferably 3 to 4 fangs/''. In this case, the dye solubilizing power of a mixed solvent containing a hydrophilic organic solvent in an appropriate ratio is greater than the dye solubilizing power of each individual solvent, so a mixed solvent is used when dissolving the dye at a high a degree. It is preferable to do so. That is, when a hydrophilic organic solvent is used alone, a composition of 60 to 70 parts of water and 40 to 30 parts of a single organic solvent usually only solubilizes an oil-soluble dye by about 2 to 3 parts/J. When two or more types of hydrophilic organic solvents are mixed, for example, when a mixed solvent of 60 parts of ethylene glycol, 30 parts of butyl cellosolve, and 10 parts of cyclohexanone is used, 60 to 70 parts of water and 40 to 30 parts of the mixed organic solvent are used. In the composition, an oil-soluble dye can be solubilized with a culm degree of 3 to 59/J. Therefore, when obtaining a colored liquid having a desired dye temperature, the type of solvent, the mixing ratio of the solvent, the mixing ratio of water and solvent, etc. are appropriately selected to prepare the colored liquid.
