ABSTRACT:
Process of forming prepasted wallcovering comprising a porous surface that carries a dry coating of polymer particles that become adhesive when wetted by water is made by applying to the surface a dispersion of the particles in a non-aqueous liquid that is stabilized by a polymeric stabilizer and then evaporating the non-aqueous liquid. A dried residue of the dispersion must not form a coherent film and should have a softening point substantially independent of the softening point of the polymeric stabilizer. The polymeric stabilizer is preferably an oil. The non-aqueous liquid is preferably relatively non-volatile.
