ABSTRACT:
Composite polyisocyanate addition products are formed from (1) the reaction product of a compound having at least two isocyanate-reactive hydrogen atoms and a molecular weight of from 400 to 10,000, a polyisocyanate and a catalyst which is a diffusion stable amino alkyl urea having tertiary amino groups and corresponds to the formula ##STR1## in which R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.7 and n each represent specified groups or values and (2) another different material such as polyvinyl chloride, ABS, lacquers and textiles. Known additives such as blowing agents, chain extenders and foam stabilizers may optionally be used in the production of reaction product (1). The composite materials of the present invention which are particularly useful in the production of bedding and seating furniture, seats used in transport means, dashboard panels, arm-rests and for other similar applications are characterized by their lack of discoloration due to the diffusion of the catalyst employed in producing reaction product (1).
