There was a thing as described in the -76563 gazette. This paint is a reaction-curable acrylic paint that tries to make it hydrophilic by using a phosphate ester monomer and colloidal silica. Colloidal silica and several acrylate monomers are used as paint monomer components. It is intended to give a coating film that is durable by blending a monomer, phosphate ester type monomer, glyceryl glycidyl ether acrylic acid ester, etc., and can effectively spread water drops that adhere to the surface by the effect of wetting. is doing. Addition of only the phosphate ester type monomer, or addition of the phosphate ester type monomer and colloidal silica gives the initial antifogging property but the durability is inferior. In addition, durability was able to be secured by a complicated combination by blending glyceryl glycidyl ether acrylate.

As a result of the hydrophilicity evaluation described above, water showed a state where it spreads to 7 cm 2 in the wetted area of water as in Example 1, indicating that the hydrophilicity was sufficiently exhibited. Also in this example, the dispersant and the leveling agent did not need to be added as in Example 1, and the hydrophilicity was not impaired even with a paint colored with a pigment.

る。As described above, the hydrophilic paint according to claim 1 of the present invention is a paint containing inorganic oxide particles and a fluorine-based surfactant or a silicone-based surfactant. By using a combination of surfactants, the water that wets the surface of the coating film exhibits a hydrophilic property that allows the water to remain spread without being converged into water droplets.
Therefore, since the water on the surface of the coating film spreads in the form of a thin film, the surface area is larger than that of spherical water, and therefore the time required for drying can be greatly shortened. In addition, since it contains an inorganic oxide, it has high surface hardness and excellent wear resistance. Furthermore, when silica gel or silica particles are used as the inorganic oxide, a transparent or translucent coating film is obtained, and it can be used as a coating material for overcoat.

という効果が得られる。The hydrophilic coating composition according to claim 2 has a fluorine-based surfactant having a perfluoro chain, an ethoxyl group,
By using those containing ether groups such as ether groups such as propoxyl group, polyethylene oxide, polypropylene oxide, etc., high hydrophilic performance can be obtained,
At the time of drying, the effect of the perfluoro chain protruding to the surface of the coating film makes it difficult for dirt such as oil to adhere, and the attached dirt can be easily removed by water that wets the surface of the coating film.

の効果が得られる。The hydrophilic coating film according to claim 3 has a dimethylsiloxane chain in the silicone-based surfactant and contains an ether group such as an ethoxy group, a propoxy group, an ether group such as polyethylene oxide or polypropylene oxide. By using, it is possible to obtain high hydrophilic performance, and the dimethylsiloxane chains that line the coating surface make it difficult for dirt such as oil to adhere when dry, and the adhered dirt can be removed by water that wets the coating surface. The same effect as that of the fluorine-based surfactant of claim 2 is obtained in that it is easily removed.
