The instant invention is directed to a process for the production of an inorganic-organic foam composition comprising reacting an organic, nonionic hydrophilic polyisocyanate with an aqueous alkali metal silicate in the presence of a catalyst and a blowing agent, the improvement wherein said aqueous alkali metal silicate contains from 0.1 to 15% by weight, based on the weight of the aqueous alkali metal silicate, of a compound of the formula: ##STR1## wherein A is selected from the group consisting of N, P and S, wherein R, R', R' and R'' may be the same or different and are selected from the group consisting of allyl, vinyl, C.sub.1 to C.sub.17 alkyl or mono- or polyhydroxy substituted alkyl, C.sub.6 to C.sub.10 aryl or mono- or polyhydroxy substituted aryl, C.sub.7 to C.sub.22 aralkyl or mono- or polyhydroxy substituted aralkyl, and C.sub.7 to C.sub.22 alkaryl or mono- or polyhydroxy substituted alkaryl,

The present invention is concerned with a process for dry printing or dyeing of sheets. A foam structure is printed or dyed and placed in contact with the sheet to be treated. The composite is subjected to sufficient heat and pressure to destroy the foam structure without significantly damaging the sheet. The result is the sheet surface now appears to carry the printing or dyeing. Among the suitable carrier foams are polyurethane foams. The process finds particular utility in coloring difficult to dye substrates such as cotton, fiber glass or asbestos fabrics with water insoluble dyes.
