Zusammenfassung:	To provide a thick film-type floor coating material that has high hardness and is less prone to discoloration, in order to solve the problem that if a white or light-colored thick film-type floor coating material is used, the color changes so as to be visible to someone due to ultraviolet light, and a thick film-type floor coating material that has solved this disadvantage has been known, but hardness thereof has not been sufficient.SOLUTION: A thick film-type floor coating material includes a main agent containing polyol, and a hardening agent containing MDI and methylene-based diisocyanate. The main agent further includes an ultraviolet absorber, a photostabilizer, aluminum oxide, and a catalyst.SELECTED DRAWING: None 【課題】白色や淡彩色の厚膜型塗り床材を使用すると、紫外線により、人が視認できる程度に色が変化するという問題が生じていた。この問題を解決した厚膜型塗り床材が知られているが、硬度が十分なものではなかった。そのため、高硬度、且つ、変色しにくい厚膜型塗り床材を提供する。【解決手段】ポリオールを含む主剤と、ＭＤＩとメチレン系ジイソシアネートとを含む硬化剤とを含み、前記主剤には、さらに紫外線吸収剤と、光安定剤と、酸化アルミニウムと、触媒と、を含むことを特徴とする厚膜型塗り床材。【選択図】なし
