METHOD FOR PRODUCING AZO-BASED PIGMENT MICRO-PARTICLE, AZO-BASED PIGMENT MICRO-PARTICLE OBTAINED FROM THE SAME, COLORING PHOTOSENSITIVE RESIN COMPOSITION AND PHOTOSENSITIVE RESIN TRANSFER MATERIAL COMPRISING THE SAME AND COLOR FILTER AND LIQUID CRYSTAL DISPLAY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a nano-size azo pigment micro-particle having a sharp particle diameter distribution peak and a method for producing the micro-particle, to provide the azo-based pigment micro-particle exhibiting excellent characteristics such as high contrast when used in a color filter and affording a thin film of the color filter and a method for producing the micro-particle, to provide the color filter affording excellent color display by using the azo-based pigment micro-particle and a liquid crystal display using the same and to provide a coloring photosensitive resin composition and a photosensitive resin transfer material used therein.;SOLUTION: The method for producing the azo-based pigment micro-particle by which a pigment dispersing agent having an amino group is made to coexist when a pigment solution comprising an azo-based pigment dissolved in a good solvent is mixed with a solvent which is compatible with the good solvent and provides a poor solvent for the azo-based pigment to produce the azo pigment as the nano-size micro-particle.;COPYRIGHT: (C)2007,JPO&INPIT
