  • Antiviral agents are thought to be able to inactivate viruses, for example, when viruses present in the air approach the surface of the antiviral agent. For this reason, in a coating film formed using a coating composition containing an antiviral agent, the virus can approach the antiviral agent located near the surface of the coating film, which is the surface that is in contact with air. Can inactivate viruses well. However, the virus cannot approach the antiviral agent located inside the coating film away from the surface or on the side of the coating film that is not in contact with the air, for example, the back side, and the antiviral agent has poor performance. You may not be able to perform to your full potential.

  • antiviral performance refers to the ability to reduce or eliminate the ability to infect viruses, and can be evaluated based on the antiviral activity value.
  • antiviral agents are thought to be able to inactivate viruses, for example, when viruses present in the air approach the surface of the antiviral agent. Therefore, in a coating film formed using a coating composition containing an antiviral agent, the antiviral agent located near the surface of the coating film that is in contact with air can efficiently inactivate the virus.

This is because the amount of moisture absorption of the coating film of the coating composition is within a predetermined range, and when the coating film absorbs moisture, the virus enters the coating film together with the moisture, and the inside of the coating film separates from the surface of the coating film. It is thought that this is because the antiviral agent also functions effectively because it approaches the surface of the antiviral agent that is arranged in such a manner. As a result, it is possible to exhibit higher antiviral performance than, for example, a coating film using a conventional coating composition with the same amount of antiviral agent added.
