In addition, a light stabilizer such as an ultraviolet absorber or a radical scavenger may be added to such an aqueous coating material in order to improve the weather resistance of the formed coating film. However, the light stabilizer such as the ultraviolet absorber and the radical scavenger is usually made of an oily organic compound. Therefore, there is a problem that even if a light stabilizer is simply added to the water-based paint, the light stabilizer is not well dispersed in the water-based paint, and the formed coating film does not exhibit sufficient weather resistance. Further, there is a problem that the light stabilizer is separated during storage and the storage stability is poor.

示されている。Therefore, in order to obtain an aqueous paint capable of forming a coating film having excellent weather resistance, a method of increasing the amount of the light stabilizer added, a method of increasing the dispersibility of the light stabilizer by using an emulsifier,
A method of previously dissolving a light stabilizer in an oil-based film-forming aid or the like and then adding this together with the film-forming aid has been studied. In addition, in addition, a method of dispersing a light stabilizer in an aqueous coating composition by polymerizing a raw material monomer of a resin which is a coating film forming component in a system to which a light stabilizer is added in advance is disclosed in Patent No. It is disclosed in Japanese Patent No. 3056427.

に光安定剤を混合する場合には適用できなかった。However, if a large amount of a light stabilizer which is difficult to disperse is added to the water-based paint, the cost of the light stabilizer becomes high, and the formed coating film tends to be tacky. There was a problem that a coating film could not be obtained. Further, even with a method of simply using an emulsifier or a method of previously dissolving a light stabilizer in a film-forming aid and adding it, there is a limit to the improvement of the dispersibility of the light stabilizer, and also sufficient weather resistance is exhibited. There was a problem that a coating film could not be obtained. Also, there is a method of increasing the dispersibility of the light stabilizer by adding an emulsifier excessively, but the addition of an excessive emulsifier caused a decrease in water resistance of the coating film. Furthermore, Patent No. 30
In the method disclosed in Japanese Patent No. 56427, it is necessary to add a light stabilizer in the step of polymerizing a resin which is a coating film forming component. Therefore, a user of an aqueous paint appropriately adds a light stabilizer to a commercially available aqueous paint. Not applicable when mixing.

ン中の安定性が低下する。The light stabilizer aqueous emulsion of the present invention is an emulsion composition in which the light stabilizer is stably emulsified and dispersed by the action of an emulsifier, and the light stabilizer is 20 to 85% by mass, preferably 30 to The content is 70% by mass, which is higher than the conventional concentration. Therefore, an aqueous emulsion paint capable of forming a coating film having excellent weather resistance can be obtained by appropriately adding this to a commercially available general aqueous paint or the like. Here, when the content of the light stabilizer is less than 20% in the light stabilizer aqueous emulsion, it is necessary to add a large amount in order to impart sufficient weather resistance. As a result, in the obtained aqueous emulsion paint, the concentration of the resin component, which is a coating film forming component, decreases, so that the solvent drying rate at the time of forming the coating film becomes slow and the composition becomes unsuitable for the paint. Further, the lower the concentration of the light stabilizer, the higher the transportation and storage costs of the light stabilizer aqueous emulsion per unit weight of the light stabilizer, which is not preferable. When the content of the light stabilizer exceeds 85% in the light stabilizer aqueous emulsion,
The light stabilizer is phase-separated, and the stability in the light stabilizer aqueous emulsion is reduced.

0 parts by weight of an emulsifier is mixed and dispersed, and a small amount of water of about 1 to 10 parts by weight is added dropwise under stirring to prepare a water-in-oil emulsion in which water is dispersed in a light stabilizer. Then, by further adding an appropriate amount of water to this water-in-oil emulsion to invert the phase, an emulsion having a light stabilizer dispersed in water, that is, a light stabilizer aqueous solution that is an oil-in-water emulsion Make an emulsion.
By such a phase inversion emulsification method, a light stabilizer aqueous emulsion containing 20 to 85 mass% of a light stabilizer can be produced.
