PURPOSE: Provided is an aqueous dispersion for a colored resin, which has excellent water resistance, photo-resistance, chemical resistance, solvent resistance, clear color tone, storage stability and heat curability. A water dispersible colored resin using the aqueous dispersion is also provided. CONSTITUTION: The aqueous dispersion for a colored resin is characterized in that the aqueous dispersion is an emulsion polymer obtained by the emulsion polymerization of the mono(meth)acrylic maleate of the formula 1 and an ethylenically unsaturated monomer, wherein R is hydrogen or a C1-C6 alkyl group, and n is an integer ranged from 1 to 6. Preferably, the ethylenically unsaturated monomer is a cyano group-containing monomer, hydroxy-containing monomer, a styrene monomer or a (meth)acrylate monomer. The water dispersible colored resin comprises 100 parts by weight of the emulsion polymer and 1 to 10 parts by weight of a dye.
