PROBLEM TO BE SOLVED: To provide a solvent free coloring composition having extremely good abrasion resistance under wet condition and scrub washing resistance in wet condition even at high pigment volume concentration (PVC) of more than 75%. SOLUTION: The coloring composition containing a binder (I), a pigment (II), a pigment dispersant (III), optionally an inorganic filler (IV) and an auxiliary (V), but not a solvent is provided, wherein the main component of the binder (I) is a copolymer which is produced in an aqueous emulsion using a free radical by monomer mixtures consisting of a monomer (a) having a glass transition temperature of less than 20 deg.C when forming homopolymer, a monomer (b) having a glass transition temperature of more than 50 deg.C when forming homopolymer, an acidic monomer (c), and another monomer (d). |
