ABSTRACT:
A process for producing a condensed resin dispersion, which comprises subjecting an aldehyde and a compound condensable with the aldehyde, or their precondensate, to a condensation reaction in a dispersion medium consisting essentially of water and/or an organic solvent, to precipitate fine condensed resin particles which hardly settle in said dispersion medium, and then replacing the water and/or the organic solvent by an active hydrogen-containing compound having at least two active hydrogen-containing groups reactive with isocyanate groups.
