An aqueous resin dispersant having a good water resistance and prepared by subjecting a radical-polymerizable ethylenically unsaturated monomer, a dimethylpolysiloxane having in its molecule a radical-polymerizable unsaturated double bond, and a radical-polymerizable monomer represented by formula (A) or (B) to free-radical polymerization in the presence of a reactive emulsifier, an oil-soluble polymerization initiator, and water, wherein R 1 represents (C 2 H 5 O) 2 or (CH 3 O) 2 and R 2 represents (C 2 H 5 O) 3 or (CH 3 O) 3 . |
