Description of the Related Art Conventionally, decorative papers for walls and ceilings for the purpose of antibacterial and deodorizing properties include, for example, an antibacterial agent in which a metal is carried on an adsorbent on a base material and a deodorizing agent for activated carbon fine particles. Are coated with a polyvinyl chloride resin or the like, or are laminated with a film in which an antibacterial agent and a deodorant have been kneaded, but their functional effects are low for their content, and their functional effects are sustained. There are issues such as not doing. Also recently,
Photocatalyst technology that irradiates semiconductors with light to generate active oxygen and acts as an antibacterial agent and decomposes odorous substances has attracted attention.As an example of its use, photocatalyst particles are kneaded into a thermoplastic resin film, Alternatively, there is a type in which a photocatalyst functional layer is provided by coating by adding it to a thermoplastic resin liquid, etc. However, since the surface of the photocatalyst particles is coated with a resin and is not in direct contact with the outside air, it has antibacterial properties, Not only can not be sufficiently exhibited, but also when the photocatalyst particles are irradiated with light, the thermoplastic resin coating the surface of the photocatalyst particles is decomposed and destroyed by the photocatalyst particles. There is a problem that embrittlement of the layer or the thermoplastic resin film and falling off of the photocatalyst particles are caused.
