PROBLEM TO BE SOLVED: To obtain a water-based coating material composition for road surface marking excellent in drying properties, abrasion and fouling resistances and adhesion, etc., to the road surface. SOLUTION: This water-based coating material composition for road surface marking is obtained by blending an alkoxysilyl group-containing acrylic emulsion containing an acrylic copolymer having >=150000 average molecular weight, 0-70 deg.C glass transition temperature and alkoxysilyl groups and >=43wt.% solid concentration in an amount of 100 pts.wt. expressed in terms of the solid content with 60-200 pts.wt. color pigment and 100-400 pts.wt. filler. |
