Abstract

1391999 Laminates BAYER AG 12 May 1972 [14 May 1971] 22404/72 Heading B5N [Also in Divisions C3 and B2] Laminates are produced by uniting a sheet of a polyurethane, which may be in microporous form, with leather or velvetone. The polyurethane sheet is prepared by a continuous multi-stage process (see Division C3).
