[PROBLEMS] To provide an anti-skid agent that has a good compatibility with water-based components contained in water-based paints, and that has excellent smoothness, sharpness, and finished appearance of a coating film formed by coating with the water-based paint. provide. An anti-waxing agent for a water-based paint has a chemical formula (1) CH 2 = C (R 1) -COO- (C m H 2m O) n -R 2 ··· (1) 5 to 90 parts by weight of an ether group-containing alkyl (meth) acrylate monomer (A) represented by the formula (2) CH 2 = C (R 3) -COO-R 4 ··· (2) And a copolymer with 95 to 10 parts by weight of the alkyl (meth) acrylate monomer (B) represented by the formula (1), wherein the copolymer has a weight average molecular weight of 3000 to 500,000 and a cloud point of 35 to 85. It shall be ℃. [Selection figure] None |
