  • Printing process
    Patent number: 3931432
    Abstract: Process for gravure or flexographic printing of flexible substrates wherein the printing vehicle comprises a dispersion of film-forming polymer particles in an inert organic liquid, the dispersion being stabilised by a defined polymeric stabiliser and being of such a composition that after evaporation of not more than 50% by weight of the organic liquid the residue is a stable dispersion which can bleed homogeneously with fresh dispersion, and wherein the polymer particles are subsequently integrated upon the substrate.
