Abstract | The present invention provides a pigment dispersion for a colour filter having excellent storage stability and low viscosity, which can form a cured film with excellent contrast, a method for manufacturing same, a colouring composition comprising said pigment dispersion for a colour filter, and a colour filter. Disclosed are: (1) A pigment dispersion for a colour filter comprising a pigment dispersant having a structural unit derived from a dialkylaminoalkyl (meth)acrylamide (A) and a structural unit derived from an alkoxypolyalkylene glycol (meth)acrylate (B), with a rate of quaternarization of 10 to 80 mol%, an organic pigment and an ether-based organic solvent; (2) a colouring composition for a colour filter comprising said pigment dispersion; (3) a method for manufacturing the pigment dispersion of (1); and (4) a colour filter manufactured using the pigment dispersion described in (1).
La présente invention concerne une dispersion de pigment pour un filtre coloré ayant une excellente stabilité de stockage et une faible viscosité, qui peut former un film durci ayant un excellent contraste, son procédé de fabrication, une composition de coloration comprenant ladite dispersion de pigment pour un filtre coloré et un filtre coloré. L'invention concerne : (1) une dispersion de pigment pour un filtre coloré comprenant un dispersant de pigment ayant une unité structurale issue d'un dialkylaminoalkyl(méth)acrylamide (A) et une unité structurale issue d'un (méth)acrylate d'alcoxypolyalkylène glycol (B), présentant un taux de quaternisation de 10 à 80 % en mole, un pigment organique et un solvant organique à base d'éther ; (2) une composition de coloration pour un filtre coloré comprenant ladite dispersion de pigment ; (3) un procédé de fabrication de la dispersion de pigment de (1) ; et (4) un filtre coloré fabriqué à l'aide de la dispersion de pigment décrite dans (1). |
