<p>PURPOSE: Imitation leather in which a resin layer of a base sheet is formed by fluorine-containing polyurethane is provided which is free from problems associated with the relevant conventional techniques, made from inexpensive materials, and excellent in water repellency/oil repellency and antifouling tendency, abrasion resistance and non-tackiness. CONSTITUTION: This imitation leather is composed of a base sheet and a resin layer at least on one side of the base sheet, wherein the resin layer comprises a polyurethane having a side chain derived from a fluorine-containing diol represented by the general formula(I). In formula, R1 is C1-20 perfluoroalkyl or perfluoroalkenyl; X is C1-10 alkylene, alkenylene or -O-phenyl-(CH2)n-(n is 0 to 6); Y is a direct bonding, -O-, -NH-, or P0-NH-(P0 is C1-6 alkylene), Z is a direct bonding, or -N(R1)R-(R is C1-20 alkylene, R1 is H, or C1-6 alkyl); R1 and R2 are divalent organic groups; and P3 is an aliphatic, alicyclic or aromatic diisocyanate residue.</p> |
