Disclosed is a pigment-dispersible compound (pigment dispersant) excellent in compatibility with a wide range of resins and excellent in pigment dispersibility. A pigment-dispersing polyallylamine derivative represented by the general formula (1), and a pigment dispersant containing the same as an active ingredient.n n n [Chemical Formula 1]n n n n n n n n In this formula,n n n R 1 is a polycondensation product of a polyester, a polyamide or an ester and an amide by forming a salt (primary ammonium salt) through the formation of a free amino group or a covalent acid amide bond of an amino group of a polyallylamine) And at least one of n R < 1 > is a residue having a covalent bond;n n n n is an integer from 2 to 1,000;n n n X and Y are independently of the other hydrogen, a polymerization initiator residue or a chain transfer catalyst residue. |
