Description

201038678 6. TECHNOLOGICAL FIELD OF THE INVENTION [Technical Field] The present invention relates to a pigment-dispersed composition containing build-up pigment microparticles, a color-sensitive photosensitive resin composition using the same, and an inkjet ink for color filters. And photosensitive resin transfer materials, and color filters and liquid crystal display devices using the same. [Prior Art] In recent years, the quality of image-related precision devices such as color image sensors and color liquid crystal display devices has been rapidly increasing. It is reflected that the 'color filter' also strongly requires an improvement in display performance led by comparison. Based on such a viewpoint, in view of the color material of the color filter, an organic pigment is used instead of the dye, and recently, pigment fine particles having a nanometer size level and monodisperse and stable are required. Furthermore, a method of manufacturing a novel color filter using ink jet technology is reviewed. Therefore, it is expected that the degree of freedom in design will be greatly increased. The cost is drastically reduced, and a dispersion composition of pigment microparticles suitable for exhibiting sufficient performance is required. The method for producing the organic pigment particles as described herein is generally a crushing method such as a bead milling method or a salt milling method. In the above honing method, in order to sufficiently refine the organic pigment to be dispersed in the composition, a lot of time and energy are required. Also, the types of pigments available are limited. Moreover, as the pigment is refined, the dispersed composition exhibits a high viscosity, which may be gelled in the storage as the case may be. For this, a manufacturing method for producing a pigment dispersion composition having high dispersion stability by an accumulation method has recently been developed. This method is suitable for obtaining fine 201038678 pigment particles, and specifically discloses a method of mixing a pigment solution with a weak solvent to precipitate nano particles and adding a specified polymer compound (see Patent Documents 1 and 2). It was attempted to use this dispersion composition to manufacture a color filter, which was highly contrasted. CITATION LIST OF THE INVENTION PROBLEMS TO BE SOLVED BY THE INVENTION The problems to be solved by the invention are as described in the above Patent Documents 1 and 2. The dispersion composition does have a high contrast effect when it is used as a color filter. On the other hand, the color filter is usually subjected to processing such as development, post-baking, and UV cleaning at the time of molding, so that cracks (surface irregularities) occur on the surface of the colored film. If the crack is formed, the color filter or the dimensional accuracy of the manufactured color filter is lowered, and the contrast is significantly deteriorated. The inventors of the present invention have focused on this point, and have an object to solve the above-mentioned characteristic use in a color filter produced by using a dispersion composition containing pigment fine particles (hereinafter, simply referred to as "accumulated pigment fine particles") prepared by an accumulation method. problem. That is, the object of the present invention is to provide a pigment dispersion composition having a dispersion stability suitable for producing a color filter containing accumulated pigment particles.
