Abstract (en)
[origin: EP0487497A1] In a process for diminishing the water vapour permeability of paper, cardboard or the like, the paper is coated with an applied medium. Tightness to water vapour is achieved by forming the applied medium from a free rosin size dispersion which contains additives for improving the film-forming properties.
