A water-based resin dispersion, a method for producing the water-based resin dispersion, and its applications. The water-based resin dispersion of the invention is excellent in permeability, leveling property and chemical stability. The water-based resin dispersion is produced by causing reaction of macromonomer composition and a vinyl monomer in an aqueous medium. The macromonomer composition is obtained by polymerization of a monomer mixture in a temperature range between 160° C. and 350° C., wherein a monomer mixture contains, with respect to the total amount of all monomers provided for the production of the macromonomer composition, for example: a vinyl monomer having alkyl group in the α-position at 10 to 80 weight %; a non-aromatic vinyl monomer having hydrogen atom in the α-position at 90 weight % or less; and styrene at 30 weight % or less. The macromonomer composition includes a hydrophilic monomer unit and a hydrophobic monomer unit.
