Description

200821362 IX. OBJECTS OF THE INVENTION: The present invention relates to a pigment dispersion composition, a photocurable composition containing the same, a color filter using the photocurable composition, and the color A method of manufacturing a filter. [Prior Art] The photocurable composition contains a pigment dispersion composition in which an organic pigment or an inorganic pigment has been dispersed, a polyfunctional monomer, a photopolymerization initiator, an alkali-soluble resin, and other components. The color filter can be produced by forming a colored pattern using a photocurable composition and using a photolithography method or the like. In recent years, color filters have been used as liquid crystal display elements (LCDs), and there is a tendency that the use of televisions (TVs) is not limited to monitors. As the use tends to expand, high color characteristics are also required in chromaticity, contrast, and the like. Also, the use of image sensors (solid-state imaging devices) requires a high degree of color characteristics. In response to the above requirements, it is required to disperse the pigment in a finer state (good dispersibility) and to disperse it in a stable state (good dispersion stability). When the pigment dispersibility is insufficient, the formed colored photoresist film may have a fringe (a zigzag pattern at the edge portion) or a surface unevenness, and the color filter or the dimensional accuracy of the manufactured color filter may be lowered, or The contrast is significantly worse. In addition, when the dispersion stability of the pigment is insufficient, in the step of producing the color filter, in particular, the film thickness uniformity is likely to be lowered in the coating step of the photocurable composition, and the photosensitive sensitivity is likely to be lowered in the exposure step. Problems such as a decrease in alkali solubility in the development step. In addition, when the dispersion stability of the material of the film 200821362 is poor, the composition of the photocurable composition is agglomerated and the viscosity is increased, and the application period is extremely short. However, when the particle size of the pigment is made fine, the surface area of the pigment particles is increased, and the cohesive force between the pigment particles is increased, and it is difficult to achieve high level of dispersibility and dispersion stability. In order to solve such problems, various pigment dispersants have been developed. Among these dispersants, copolymers containing a large monomer (an oligomer having an ethylenically unsaturated group at the terminal) are useful. It is disclosed that by using a copolymer containing the macromonomer (an oligomer having an ethylenically unsaturated group at the terminal), a pigment dispersion having a small pigment particle size and excellent dispersion stability can be obtained (for example, Refer to Patent Documents 1, 2). However, since the copolymer containing the macromonomers described in Patent Documents 1 and 2 does not have a functional group for promoting adsorption of the pigment, it does not function as a dispersing agent alone, and it is necessary to use it with other dispersing agents. Further, when φ is used as a dispersing agent for a pigment containing a copolymer of such a large monomer, the viscosity-increasing effect seen in the local molecular dispersant can be suppressed, but the pigment is not sufficiently refined, and there is a pigment. The problem of insufficient dispersion. In order to improve the dispersion stability of the pigment, a partial structure having an organic coloring material (for example, 'Reference Patent Document 3), a nitrogen-containing hetero ring (for example, refer to Patent Document 4), and a cyclic quinone imine group (for example, reference) are disclosed. Patent Document 5) A graft polymer. However, the pigment dispersion group in which the dispersibility and dispersion stability of the pigment are excellent, and the photocurable composition containing the same are not provided at present.
