摘要： A method for producing a pigment dispersion composition having excellent image density, dispersibility, and storage stability, has high resolubility, and forms an ink film having excellent marker resistance and scratch resistance. The method includes bringing a pigment (I) having a surface acidic group and a basic compound (II) having two or more ammo groups selected from a primary amino group and a secondary amino group in its molecule, into contact with each other in an aqueous medium to prepare a pigment having an unreacted surface amino group, bringing the pigment into contact with a polyisocyanate polyurethane resin (III) having two or more isocyanate end groups so that the pigment and the polyisocyanate polyurethane resin are bonded via a urea bond to prepare a dispersion of a polyurethane resin-bonded pigment (A), and heating the dispersion of the polyurethane resin-bonded pigment (A) at 40 to 100° C. for 1 to 30 days.

摘要： A toner for developing an electrostatic image is constituted by a composition containing a binder resin component and a coloring agent, wherein the binder resin component contains a low-molecular weight component having a molecular weight of at most 5.times.10.sup.4 and a branching index g' of below 1. The low-molecular weight polymer component is preferably obtained by polymerizing a second monomer in mixture with a prepolymer in the presence of a polymerization initiator comprising a peroxide having a functional group of: ##STR1## and mixed with a high-molecular weight polymer component obtained by polymerization in the presence of a poly-functional polymerization initiator, and a low-molecular weight wax. The resultant toner is characterized by a good balance between the fixability and anti-offset characteristic.
