ABSTRACT:
A floor coating composition containing one or more unsaturated urethane compounds, which is(are) obtained from an isocyanate compound(s) and a hydroxyl compound(s) as starting materials, wherein at least one of the isocyanate compound(s) and the hydroxyl compound(s) has an unsaturated bond(s), wherein the poly(alkyleneoxy) group content (as defined in the specification) is 2–16 wt % and the proportion of the number of the unsaturated bonds (as defined in the specification) is not less than 6, can form a coating film superior in staining resistance against extremely powerful staining substances and gloss retentivity against extremely great load from walking, and which permits easy polishing away of damages and color stain, as well as use of water as a solvent. When a coating object is covered with a film made from the composition, a coated material can be obtained, wherein warpage of a coating object (floor, floor material, plastic film and the like) and cracks in the film are suppressed.
