Abstract: Carbamate solutions obtained by reacting carbon dioxide with aminoalkyl-alkanolamines containing one or two terminal hydroxyl groups in hydroxyl group-containing organic solvents. Carbamate solutions, obtained by reacting alkanolamine(s) with carbon dioxide in hydroxyl group-containing organic solvent(s) with a mol. wt. of 60-600, in which the carbamate contains at least 0.51 mol bound CO2 per mol alkanolamine and the alkanolamine has the formula (I), (II) or (III) H2N-X-OH (I) HO-X-Y-OH (II) HO-X-NR -(CR R )n5-OH (III) X = -((CR R )n1NR )n2-((CR R )n3NR )n4-(CR )n5-; Y = -(NR -(CR R )n3)n4-(NR -(CR R )n1)n2-; n1, n3, n5 = 1, 2, 3 or 4; n2, n4 = 0, 1, 2, 3, 4, 5 or 6; (n2 + n4) = 1 or more; R -R = H or 1-20C aliphatic, cycloaliphatic, araliphatic or aromatic groups Independent claims are also included for processes for the production of foam, flexible foam and flexible or semi-rigid integral foam based on polyisocyanate-polyaddition products, with the aid of these carbamate solutions as blowing agents.

Abstract: An area of a first tool with a rib dividing it from a masked area is sprayed with a first color(5). After mask(3) removal the second area is sprayed another color(6). Polyurethane(PU) is cast over both colored areas to form a skin(7). The skin is demolded and located in a second tool(13) with a thin dividing plate(11) inserted into a groove dividing the colors. Applied vacuum holds the skin in position while an upper tool(10) carrying a supporting part(9) is closed over it and PU foam(14) introduced to form a backing layer. Independent claims are made for: a molding tool for manufacture of a multi-colored cast PU skin for use as an internal lining component in a vehicle and including a projection(2) for separating areas of different color and a mask(3) for covering of an area to be painted in a second color; b) a tool for manufacturing a multi-colored cast skin with a supporting layer(9) and foam(14) between them which has a thin dividing plate(11) for locating into a groove produced in the cast skin molding and vacuum for holding the skin onto the thin plate.
