<p>The opacity and brightness of a sheet of paper coated with a composition comprised essentially of a pigment and a latex of a film-forming polymer are improved when the paper after being coated is dried under conditions adapted to prevent coalescence of the polymer particles of the latex during the drying step and then subjected to a treatment adapted to cause coalescence of the polymer particles, without subjecting the coating to compressive forces during this treatment step.</p> |
