<p>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).</p> |
