The present invention relates to a core-shell emulsion resin, a method for producing the same, and a paint composition containing the same. The core-shell emulsion resin comprises a core and a shell. The core, on the basis of 100 parts by weight of polymer units for constituting the core, comprises, as the polymer units: 90 to 94.5 parts by weight of an ethylenically unsaturated monomer; 1 to 5.5 parts by weight of an amino group-, sulfur-, or phosphorus-containing hydrophilic monomer; 0.1 to 5 parts by weight of an olefin-containing crosslinking polyfunctional monomer; and 1 to 5 parts by weight of a carboxylic acid group-containing monomer. The shell, on the basis of 100 parts by weight of polymer units for constituting the shell, comprises, as the polymer units: 90 to 94.5 parts by weight of an ethylenically unsaturated monomer; 1 to 5.5 parts by weight of an amino group-, sulfur-, or phosphorus-containing hydrophilic monomer; and 0.1 to 5 parts by weight of an olefin-containing crosslinking ...
