Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an easy-to-clean marking agent for turf, which allows a line formed easily therefrom to keep sharpness without being erased by light rain and be erased easily only by water washing, which does not hinder the growth of natural turf and hardly pollutes the environment. SOLUTION: The marking agent is obtained by using a water-soluble dispersion containing polyvinyl alcohol (A), aliphatic acid-treated heavy calcium carbonate (B) and a pigment (C). It is preferable that the saponification degree of the polyvinyl alcohol is ≥90 mol%, the average particle size of the aliphatic acid-treated heavy calcium carbonate is 0.5-10 μm, the weight ratio of (B)/(A) is 1-9 and the volume ratio of ((B)+(C))/((A)+(B)+(C)) is 40-90 vol.%.
