COLORED RADIATION SENSITIVE COMPOSITION, A COLOR FILTER USING THE SAME, A MANUFACTURING METHOD FOR THE COLOR FILTER, A MANUFACTURING METHOD FOR COLORED PATTERNS, A SOLID-STAGE IMAGE TAKING DEVICE, AND A LIQUID CRYSTAL DISPLAY DEVICE CAPABLE OF SUPPRESSING THE UNEVENNESS OF COLOR DENSITY

摘要

PURPOSE: A colored radiation sensitive composition, a color filter using the same, a manufacturing method for the color filter, a manufacturing method for colored patterns, a solid-stage image taking device, and a liquid crystal display device are provided to form a cured film with even color.;CONSTITUTION: A colored radiation sensitive composition includes a pigment polymer and a solvent. The pigment polymer is polymerized by a chain-transfer agent of which LogP is 5 or less. The pigment polymer includes a structural unit with a pigment structure. The chain-transfer agent is alkyl mercaptan. The pigment structure is derived from a dipyrromethene-based metal complex or the tautomer of the complex. The dipyrromethene-based complex is obtained from metals or metal compounds, and a dipyrromethene-based compound represented by chemical formula III. In chemical formula III, R1 to R6 are respectively hydrogen atoms or monovalent substituents; R7 is a hydrogen atom, a halogen atom, an alkyl group, an aryl group, or a heterocyclic group; and no ring is formed by R1 and R6.;COPYRIGHT KIPO 2013
