Abstract:
A sheet like article produced from a polyurethane resin has a carbonate group and an oxycarbonyl group as ester groups and has uniform, elegant surface quality, a flexible, highly crease recoverable texture, and high resistance to light and hydrolysis, and also provided is a production method therefore. The sheet like article is produced by adding, as a binder, a polyurethane resin that meets requirements (I) and (II) to a fibrous base material formed mainly of ultrafine fibers: (I) a polyurethane resin such that the polyurethane resin contains, in its interior, an oxycarbonyl group and a carbonate group as ester groups; (II) a polyurethane resin such that the sum of the content of the urethane group and the content of the urea group in the polyurethane resin is 7.0 to 11.0 mass %.
