LEATHERY SHEET OBJECT, PROCESS FOR PRODUCING THE SAME, AND URETHANE COMPOUND MODIFIED WITH FLUORINATED SIDE CHAIN
Document Type and Number:
WIPO Patent Application WO/2004/001122
Kind Code:
A1
Abstract:
A leathery sheet object characterized by comprising a sheet object comprising a fibrous material and a polymeric elastomer and, contained in the object, a urethane compound modified with fluorinated side chains which satisfies the following requirements (i) to (iii): (i) the compound is constituted of a urethane-bond-containing compound having a molecular weight of 500 to 5,000 and bonded thereto 3 to 12 fluorinated side chains each having a molecular weight of 200 to 1,000; (ii) the compound has a fluorine content of 20 to 60 wt.% in terms of fluorine atom amount; and (iii) the compound has 6 to 36 urethane bonds per molecule. Also provided are: a process for producing the leathery sheet object; the modified urethane compound for use in the process; and a process for producing the modified urethane compound. The leathery sheet object is excellent in water repellency and water resistance in sections formed by cutting.
