Filed: 1999-07-21
Abstract: PROBLEM TO BE SOLVED: To exhibit a hydrophilic property from the first time of film formation by forming projecting and recessing parts exhibiting capillary phenomena to water on the surface of a coating film. SOLUTION: This coated material has a coating film 2 formed by applying a coating composition with a spin-coater, and the like, on a flat substrate 1. Projecting and recessing parts 5, 6 exhibiting capillary phenomena to water are formed on the surface of the coating film 2. The projecting and recessing parts 5, 6 on the surface of the coating film 2 has a >=5 nm and <=50 nm average surface roughness. The material of the substrate 1 is not limited in particular but usually glass, plastic, and the like, are used. As the glass, sodium glass, and the like, are used and as the plastic, polycarbonate resin, and the like, are used. Thereby, water permeates the projecting and recessing parts formed on the surface of the coating film 2.  In the coating film 2 having the projecting and recessing parts on the surface, the more recessive parts through which water can permeate deeply into the coating film 2 are, the smaller contact angle of water the coating film has, therefore, the hydrophilic property of the coating film 2 can be enhanced.
