A leather-like sheet material comprising a sheet material composed of a fiber aggregate and a elastic polymer, the sheet material containing a fluorine-containing side-chain-modified urethane compound which satisfies the following requirements (i) to (iii),
(i) said urethane compound containing a urethane-bond-containing compound having a molecular weight of 500 to 5,000 and fluorine-containing side chains having a molecular weight of 200 to 1,000 each, 3 to 12 such fluorine-containing side chains bonding to the urethane-bond-containing compound,
(ii) said urethane compound having a fluorine content of 20 to 60 % by weight as a fluorine atom, and
(iii) said urethane compound having 6 to 36 urethane bonds per molecule.
The present invention provides a process for the production of the above leather-like sheet material, a modified urethane compound satisfying the above requirements (i) to (iii) for use in the process, and a process for the production of the modified urethane compound.
According to the present invention, the leather-like sheet material is excellent in water repellency from a cut cross section and water resistance.
