  • the coating composition of the present embodiment includes a monofunctional (meth) acrylate monomer, a bifunctional (meth) acrylate monomer, a trifunctional (meth) acrylate monomer, and a tetrafunctional in addition to a pentafunctional or higher functional (meth) acrylate monomer. It is preferable to include at least one selected from the group consisting of (meth) acrylate monomers.
  • a (meth) acrylate monomer having 1 to 4 functional groups having a carbon-carbon unsaturated bond it is possible to suppress an excessive increase in the crosslinking density of the resulting hydrophilic film. Therefore, the elongation is improved in addition to the hardness of the hydrophilic film, and as a result, the peeling of the hydrophilic film can be suppressed.
  • At least one of the (meth) acrylate monomer having 5 or more functional groups and the (meth) acrylate monomer having 4 or less functional groups has a hydroxyl group in the molecule. Even when the (meth) acrylate monomer is polymerized to form a hydrophilic film, it is more preferable that the hydroxyl group remains in the hydrophilic film.
  • the base resin (acrylic resin) constituting the hydrophilic film has a hydroxyl group, the base resin itself has a high affinity for water. Therefore, even when the content of the porous material is reduced, the hydrophilicity of the hydrophilic film surface can be improved.
  • the coating composition according to the present embodiment contains a porous substance in order to impart hydrophilicity to the obtained hydrophilic film. Since the porous material has a plurality of pores, the specific surface area is large, and water molecules are easily adsorbed on the surface and inside of the porous material. Therefore, when the hydrophilic film contains a porous substance, moisture is easily adsorbed on the surface of the hydrophilic film, so that the hydrophilicity can be improved.
  • the porous material is preferably zeolite.
  • the porous material is preferably carbon particles. Zeolite and carbon particles have a large number of pores and are highly adsorbable with water molecules. Therefore, it is possible to further improve the hydrophilicity of the obtained hydrophilic film.
  • a photopolymerization initiator is a compound having a function of initiating a polymerization reaction of a (meth) acrylate monomer, and is a substance that absorbs light of a specific wavelength from an active energy ray to be excited to generate radicals and ions.
  • a photopolymerization initiator for example, at least one selected from the group consisting of benzoin ether series, ketal series, acetophenone series, benzophenone series, and thioxanthone series can be used.
  • the coating composition according to this embodiment includes a (meth) acrylate monomer having a functional group having a carbon-carbon unsaturated bond of 5 or more, a surfactant, and a porous substance.
  • the coating composition further includes a (meth) acrylate monomer, a surfactant, and a dispersion solvent for dispersing the porous material. Since the hydrophilic film obtained from such a coating composition has a highly dispersed porous substance that retains moisture, the hydrophilicity of the hydrophilic film can be increased and oil can be easily removed. Further, as the (meth) acrylate monomer, a polyfunctional (meth) acrylate monomer having 5 or more functional groups having a carbon-carbon unsaturated bond is used.
  • the coating composition according to the present embodiment can be applied to a housing member such as a kitchen member. It can also be applied to sirocco fans and propeller fans installed in the kitchen range hood.
  • the coating composition is not limited to such a house member, and can be applied to, for example, a vehicle member or a security member. Specifically, it can be applied to the surface of a vehicle-mounted lens or a security camera to impart antifouling properties.

  • drying conditions are not particularly limited as long as the dispersion solvent is removed, and heat treatment may be performed as necessary.
  • the coating composition is applied to the surface of the substrate 10 and then irradiated with active energy rays to cure the coating composition.
  • active energy rays As an active energy ray to be irradiated when the coating composition is cured, at least one of ultraviolet rays, electron beams, X-rays, infrared rays, and visible rays can be used. Of these active energy rays, ultraviolet rays or electron beams are preferably used from the viewpoint of curability and prevention of resin deterioration.
  • hydrophilic member 100 is not limited to use for the purpose of removing oil, and can be suitably used for a portion that needs to be imparted with hydrophilicity.

  • Example 9 is an example prepared in the same manner as in Example 1 except that a clay-based porous adsorbent was used instead of zeolite A.
  • Example 10 is an example prepared in the same manner as in Example 1 except that a carbon-based porous adsorbent was used instead of zeolite A.
  • the coating composition of Comparative Example 2 could not be cured even when irradiated with ultraviolet rays. This is because the (meth) acrylate monomer having 5 or more functional groups was not used, and the reactivity of the (meth) acrylate monomer was reduced by the addition of zeolite, and the coating was not sufficiently cured. Conceivable.
  • Example 9 and Example 10 When the test samples of Example 3, Example 9 and Example 10 are compared, it can be seen that all the test samples have a water contact angle of the coating of 20 ° or less. Therefore, it can be seen that clay particles and carbon particles can be used as the porous material in addition to zeolite.
