(57) Abstract: [PROBLEMS] To provide a water-based coating agent for paper, which can impart water resistance, blocking resistance and slip resistance to the paper surface without impairing the adhesiveness between the paper surface and the adhesive tape. In the presence of an aqueous graft copolymer comprising silicone macromonomer-based units, α, β-ethylenically unsaturated carboxylic acid salt-based units and other radically polymerizable monomer units. In addition, a paper coating agent comprising an aqueous resin dispersion obtained by emulsion-polymerizing a radically polymerizable monomer containing a (meth) acrylic acid ester as a main component in an aqueous medium. |
