PROBLEM TO BE SOLVED: To provide a sheet material which has high wear resistance and flexibility while maintaining a high anti-staining property.SOLUTION: In a sheet material 1, an anti-staining layer 3 is formed on a surface of a body material 2 including a base material 5 and a resin layer 6. The anti-staining layer comprises a two-liquid curable type fluorine-containing resin generated by the reaction of an alkyl silicone-containing fluororesin with a polyisocyanate. The alkyl silicone-containing fluororesin comprises a fluoroolefin, an acrylate monomer, an alkyl silicone, a hydroxyl group containing monomer, and an unsaturated carboxylic acid. The polyisocyanate includes an aliphatic-alicyclic polyisocyanate obtained by copolymerizing an aliphatic diisocyanate with an alicyclic diisocyanate. An example of the aliphatic diisocyanate includes hexamethylene diisocyanate (HDI), and an example of the alicyclic diisocyanate includes isophorone diisocyanate (IPDI). |
