Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a composition of a color filter protective film having excellent flatness and a color filter protective film. More specifically, a composition for a color filter protective film of a liquid crystal display (LCD) containing a polysilane compound and an epoxy compound, and a protective film obtained from the composition. [Prior art] The color filter protective film for LCD requires hiding the unevenness of the surface of the color ink pixels of the raw materials and the black matrix, and the flatness of the surface. When the surface of the color filter protective film is not flat, when the protective film is incorporated into an LCD panel, the LCD may cause problems such as color spots and degradation of display quality. Various compositions are disclosed for the composition for a color filter protective film. For example, Japanese Patent Application Laid-Open No. 63-2 1 877 1 discloses a composition for forming a protective film containing a hydrolyzate or a part of a hydrolyzate of an organic alkoxysilane. Furthermore, Japanese Patent Publication No. 8-30 1 67 discloses a sulfamic acid compound, an imine compound, and a composition for forming a hardening protective film containing a silyl compound having a hydrolyzable group. In addition, Japanese Unexamined Patent Publication No. 4-345608 contains a material for a color filter and a cured product thereof, which contains a compound having a diphenol structure. These compositions have the function of flattening the surface step difference generated in the color ink pixels and the black matrix of the raw materials, and can be used as a protective film for LCDs. However, these compositions have insufficient flattening performance during high-speed driving of the STN driving method and IPS driving method. In such methods, it is required to develop a protective film material having more excellent flatness during high-speed driving. Furthermore, Japanese Patent Application Laid-Open No. 9-328534 discloses a composition for a color filter protective film containing an epoxidized compound 1243917 V. Description of the Invention (2) and an xm 3¾ oxygen hardener.

The pixel difference is the height difference between the center of the red pixel and the green pixel. Next, a protective film having a film thickness of 2 μm and 5 μm was formed on the dummy color filter by the above method, and the inter-pixel step difference (d2) was obtained at the portion measured before coating. Based on the following formula (3): R = (d 2) / (d 1) (3) as the reference, find the pixel interval (d 1) before the protective film is applied and the pixel interval after the protective film is applied The ratio R of the step difference (d 2). The larger R 値 indicates lower flatness, while the smaller R 値 indicates higher flatness. It was evaluated on the following basis. ○: Excellent flatness (R is less than 0.2). Δ: The flatness is slightly better (R is 0.2 to 0.4). X: Poor flatness (R is greater than 0.4). 5. Transparency A color filter protective film was formed on the glass substrate by the above method. The transmittance of the obtained protective film was measured at a wavelength of 400 to 700 nm using a spectrophotometer "U-2000 (manufactured by Hitachi, Ltd.)" and evaluated in accordance with the following criteria. ○: Excellent in transparency (minimum transmittance is 95.5% or more). X: Poor transparency (minimum transmittance is 95% or less). 6. Surface hardness A color filter protective film was formed on the glass substrate by the method described above. The surface hardness of the obtained protective film was measured with a pencil hardness meter based on: HS-K-5400. It was evaluated on the following basis. -19-1243917 V. Description of the invention (18) 〇: Has sufficient hardness (hardness is above 3H). X: Insufficient hardness (hardness is 2H or less). Table 2 shows the evaluation results of the coating films and protective films prepared from the compositions for color filter protective films of Examples 1 to 7 and Comparative Example 1.

[Effects of the Invention] The present invention can provide a composition for an LCD color filter protective film having excellent planarization performance. In addition, by using the cured protective film composition as the protective film, a protective film having excellent flatness can be used to produce the LCD filter having excellent flatness as described above.
