Provided is a pigment-dispersible compound (pigment dispersant) which exhibits an excellent compatibility with a wide variety of resins and an excellent pigment dispersibility.
Means For Solution
A pigment-dispersible polyallylamine derivative represented by formula (I), and a pigment dispersant containing the same as an active ingredient.
wherein
R1 represents a residue in which a free amino group or an amino group of a polyallylamine is bound to a polyester, a polyamide or a copolycondensate of an ester and an amide by covalent bond (acid amide bond) formation or by salt (primary ammonium salt) formation through terminal carboxyl groups thereof, and at least one of an n-number of R1's is a residue that has the covalent bond,
n represents an integer of from 2 to 1,000, and
X and Y, independently from each other, represent hydrogen, a polymerization initiator residue or a chain transfer catalyst residue.
