In order to solve the above-mentioned problems, a non-aqueous dispersion of antimony-containing tin oxide fine powder and a hydrolysis product of silicon alkoxide (hereinafter referred to as “silica sol”) has conventionally been applied to the surface of a transparent substrate. Was applied and dried to form an antistatic film. That is, an antistatic film is formed by using a paint made of a non-aqueous dispersion containing a mixture of the above-mentioned antimony-containing tin oxide fine powder and the above-mentioned silica sol. Then, there is a cathode ray tube in which the antistatic paint is sprayed onto a display surface by spraying to form an uneven film, and an antireflection effect is imparted by light scattering (for example, Japanese Patent Application Laid-Open No. 62-176946). ,

When the antimony-containing tin oxide fine powder is added, the refractive index n of the antistatic film is n = 1.50.
It is about 1.54, and there is almost no difference from the refractive index of the glass base material as the base material or it is higher than that, so that the antireflection effect is not sufficient. Further, conventionally, an anti-reflection effect or an anti-static paint formed by forming an uneven surface using a dispersion liquid containing silicon dioxide fine particles and antimony-containing tin oxide fine powder by light scattering or spraying an anti-static paint is used. In the case of forming an uneven surface by spraying on the display surface and giving an anti-reflection effect by light scattering, the roughness of the surface of the formed uneven film is large, the haze value becomes large, and the resolution of the image is significantly reduced. There was a problem.

Furthermore, an antistatic film obtained by adding a quaternary ammonium salt or a nitrate to silica sol has an insufficient antistatic effect, and also has a defect that conductivity is deteriorated due to a decrease in humidity. In addition, a silica film formed by baking a silica sol did not exhibit a sufficient antireflection effect. Further, studies have been made to improve the color purity by adding various dyes to these coating films, but no satisfactory effect has been recognized.

Next, a method for forming a coating film using the composition for forming a film having a color purity improving function of the present invention will be described. First, as the transparent substrate to be used, a glass substrate is preferable. For example, a substrate made of non-alkali glass, alkali borosilicate glass, alumina silicate glass, lead glass, or other glass is used. A coating solution of the composition for forming a film having a color purity improving function of the present invention on the surface of the above-mentioned transparent substrate is usually coated by a spin coating method, a dipping method, a knife coating method, a roll coating method, a spray coating method. It can be formed by applying a coating method such as a gravure coating method, a bar coating method, a curtain coating method, etc., drying the coating, and further performing a baking treatment.

The thickness of the coating film is preferably 0.05 to 0.5 μm, where the thickness of the coating film at the average roughness of the fine irregularities is referred to as the film thickness. When the film thickness is 0.05 μm or less, the film strength tends to be too weak, and when it exceeds 0.5 μm, cracks tend to occur due to shrinkage of the film during drying. Further, a fine uneven surface having a height of 0.01 to 0.1 μm can be formed on the surface of the coating film.
