Abstract: PROBLEM TO BE SOLVED: To produce a membrane easily from an aqueous dispersion containing a polyurethane with the use of a mold which is used usually to produce car interior finish members.
SOLUTION: One mold is coated with an aqueous dispersion containing a polyurethane A in the form of a plane (process I), the membrane, obtained in the process I, of the aqueous dispersion containing the polyurethane A is dried (process II), as the occasion demands, the mold coated with the mono-layer membrane, which was obtained in the process II, is coated again with the aqueous dispersion containing the polyurethane A in the form of a plane to produce a multilayer membrane (process III), the membrane of the aqueous dispersion containing the polyurethane A, which was newly formed in the process III, is dried into one membrane layer (process IV), and as required, the processes III, IV are repeated 5-50 times.

Abstract: PROBLEM TO BE SOLVED: To obtain the subject solution improvable mechanical properties of a foam, e.g. wear resistance, tensile strength and appearance of an outer layer skin by including a specific alkanolamine and carbon dioxide in bonded state. SOLUTION: This solution is obtained by reacting at least one kind of alkanolamine with carbon dioxide in at least one organic compound having 60-600 molecular weight and at least one piece of hydroxyl group as a solvent. The resultant compound contains bonded state of carbon dioxide in an amount of at least 0.51 mol. per 1 mol. of alkanolamine and the alkanolamine is expressed by one of the formulae: NH2-X-OH, OH-X-Y-OH and OH-X-NR9-(CR7 R8)n5-Y-OH (X is formula I; n1, n3 and n5 are each 1-4; n2 and n4 are each 0 or 1-6; R1-R9 are each H, a 1-20C aliphatic or the like).

Abstract: A self-supporting, carrier-free polyurethane film contains a polyurethane which contains one or more functional groups which can be neutralized to give ionic groups and thus allow the film to be obtained by electrophoretic deposition. The polyurethane may also contain ionic groups in addition to the above functional groups. An Independent claim is also included for production of a self-supporting, carrier-free polyurethane film by depositing a polyurethane containing at least one ionic group on an electrically-conductive surface or mold used as an anode.
