Abstract
A process for producing an inorganic compound-containing urea resin, which comprises adding an acidic gelling agent to an aqueous urea-formaldehyde precondensate solution to prepare a urea resin-containing product, and either (1) mixing the product with a reactant which reacts with the gelling agent to form inorganic particles substantially insoluble in water, or (2) separating the urea resin from the product, mixing the resin-freed mother liquor with such a reactant as stated above, and mixing the resulting inorganic particles with the separated urea resin.
