METHOD FOR PRODUCING FINE PARTICLES OF QUINACRIDONE PIGMENT, QUINACRIDONE PIGMENT FINE PARTICLES OBTAINED THEREBY, COLORING PHOTOSYNTHETIC RESIN COMPOSITION INCLUDING THE SAME AND PHOTOSENSITIVE RESIN TRANSCRIPTION MATERIAL, AND COLOR FILTER AND LIQUID CRISTAL DISPLAY DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide quinacridone pigment nano-fine particles having a sharp distribution peak and a method for producing the same, further to provide a quinacridone pigment fine particles that shows excellent properties, when it is used for reflecting color filter, and a method for producing the same. In addition, to provide a reflection type color filter that can develop excellent image display having high contrast or the like by using the quinacridone pigment particles and provide a liquid crystal display using the same. Further, provide a coloring photosensitive resin composition to be used in them and photosensitive resin transcription material.;SOLUTION: In the method for producing fine particles of quinacridone pigment, when quinacridone pigment solution in a good solvent is mixed with a solvent that is compatible with the good solvent and is poor to the quinacridone pigment to prepare nano-fine particles of quinacridone pigments, a pigment dispersant including nitrogen is combined.;COPYRIGHT: (C)2007,JPO&INPIT
