Problems solved by technology

However, the color filter formed using the photosensitive composition has a problem of insufficient adhesion to transparent conductive films such as ITO and IZO or inorganic films such as SiNx films and SiOx films formed thereon.
[0004] In addition, in the field of color filter technology in recent years, reduction of exposure amount and shortening of tact time have become mainstream, but the problem of insufficient solvent resistance of pixels formed with conventional colored radiation-sensitive compositions is becoming prominent

Abstract

The present invention relates to a coloring composition, a color filter and a color liquid crystal display element. The novel coloring composition provided by the invention has excellent binding firmness with transparent conductive film and inorganic film and can form the pixel with excellent solvent resistance with a low exposure amount. The coloring composition is characterized by comprising the following components: (A) a colorant, (B) an adhesive resin, (C) a multifunctional momomer and (D) a polyhedral oligomeric silsesquioxane with at least group selected from sulfhydryl and polymeric unsaturated group.

Description

technical field [0001] The present invention relates to a coloring composition, a color filter, and a color liquid crystal display element, and more specifically, relates to a color liquid crystal display device for forming a transmissive or reflective type, a color camera tube element, an organic EL display element, A coloring composition for a colored layer useful for a color filter used in electronic paper, a color filter having a colored layer formed of the coloring composition, and a liquid crystal display element including the color filter. Background technique [0002] Conventionally, when a colored radiation-sensitive composition is used to manufacture a color filter, a known method is to apply a colored radiation-sensitive composition on a substrate or a substrate on which a light-shielding layer of a desired pattern is formed in advance, and after drying, The dried coating film is irradiated with radiation in a desired pattern shape (hereinafter referred to as "exp...
