ABSTRACT:
A method for preparing high resolution negative-working wash-off relief images comprising the sequential steps of: (a) providing a non-photosensitive, aqueous processable layer, preferably on a substrate, said layer comprising a dispersion of solvent-coalesceable particles in a polymer matrix; (b) imagewise applying an ink to the non-photosensitive layer to coalesce the particles and form a water-insoluble polymer blend between the particles and the polymer matrix in the ink applied areas; and (c) washing the layer with an aqueous developer solution to remove the non-ink applied areas of the layer.
