COLORED PHOTOSENSITIVE RESIN COMPOSITION WITH DIKETOPHYRROLOPYRROLE-BASED RED DYE, A COLORED PATTERN, A COLOR FILTER, AND A LIQUID CRYSTAL DISPLAY DEVICE COMPRISING THE SAME

摘要

PURPOSE: A colored photosensitive resin composition a color pattern, a color filter, a liquid crystal display device, an image sensor, and an image pick-up device are provided to have excellent solvent resistance.;CONSTITUTION: A colored photosensitive resin composition comprises a colorant, an alkali soluble resin, a photopolymerizable compound, a photopolymerization initiator, and a solvent. The dye in the colorant is diketophyrrolopyrrole-based red dye, and comprises a structure unit indicated in chemical formula 2. In chemical formula 1, R is a C2-C9 alkyl. In the chemical formula 2, each of R1 and R2 is independently hydrogen or methyl. The content of the structure unit indicated in the chemical formula 2 in the alkali soluble resin is 3-80 mol% based on the total mole numbers of the alkali soluble resin.;COPYRIGHT KIPO 2013
