This is an effect much sought was definitely smoother than sample A, whilst after for many purposespbut it is a dlstinct-dissample B was noticeably rougher than A.
  • the one property which determines the printing quality of coated paper above everything else is its degree of smoothness.
  • only enough adhesive is used to assure absence of picking or lifting on the press, for the reason that excess adhesive in the coating, other conditions being the same, impairs the gloss and smoothness imparted by the calendering.
  • With the Bradner process the use of excess adhesive has the opposite effect. It enhances the gloss obtainable and improves the smoothness.
  • the decreased absorbency makes it possible, by the use of gloss inks, to secure a gloss on the printing ink commensuratewith the gloss on the paper itself.
  • the decreased absorbency also reduces finger-marking which is otherwise especially dis-v figuring in the case of brightly colored high-gloss by laboratory tests.
  • excess adhesive we mean an excess over what would be commonly employed by an experienced paper-maker to insure the adhesion of the coating to the paper. This insurance'involves a factor of safety over what might be the absolute minimum as would be determined
  • Different batches of clay and other fillers supposedly of the same composition vary from one another in the amount of adhesive required to prevent picking of the coating in the printing operation. It is common practice, therefore, in making up the formulae for coating compositions to designate the amount of adhesive which experience has indicated ,will insure a. proper adhesionof the coating to the paper stock,

  • a transparent coating is desirable, and in such cases if fillers havinga refractive index nearly equal to that of the desired adhesive such as clayv and casein) are used a coating may contain as much as 50 per cent or more of mineral filler and still be substantially trans: parent.
  • a 7 is shellac. Due tothe color in the shellac its use is largely a confined to coloredpaper such as used for decora- For colored coatings dyes, colored pigmentsfor mixtures of dyes and pigments may be employed.
  • thermoplastic 'gumsor resins 1 '30, surface is obtained by cooling in contact with may be used, in which case the required cast' thenonadhe'ring finishing surface, and the solvent or suspending liquid may be dispensed: with entirely.
  • Ammonium stearate in the quantity specified in the above mentioned Montgomery and Bradner patent may be used with advantage in the examples given above to facilitate the casting operation.
  • the coatings produced by the Bradner process as presenting a gloss finish.
  • the paper embodying the invention of the present application is not, however, limited to paper presenting a glossfinish. Either the gloss-finish or the matte flnish of the Bradner process may be emplo' yed for thepaper of the present application. Matte-finish paper is frequentlyused for" printing withf" gloss inks, pleasing artistic effects and contrasts being thereby secured. Also the paper of the present invention possesses superior printing qualities in the'matter of definition, uniformity,
  • coated printing paper which comprises applying to paper a v coating composition comprisingfiller and adhesive, said adhesive being present in an amount greater than 30% by weight of the coating composition calculated on a dry basis and imparting to the surface of the coating material a high degree of smoothness by causing the coating to harden in contact with a smooth, non-adhering surface.
  • Process of manufacturing coated printing paper which comprises applying to paper a coating composition comprising filler and adhesive, said adhesive being present in an amount greater than 30% by weight of thecoating composition calculated on a dry basis, contacting the coated paper with a non-adhering finishing surface while the coating is in a plastic condition and rendering the coating non-plastic while in contact with said finishing surface.
  • Process of making cast surfaced coated paper which comprises applying to paper a coating composition-comprising an aqueous dispersion containing shellac, the shellac comprising more than 30% by weight of the total coating calculated on the dry basis, and imparting to the surface of the coating material'a high degree of smoothness by drying the coating in contact with a smooth, nonadhering surface.
