coating binders and carriers is applied to the web substrate on a standard paper machine the amount of thermoset preferably at least about 25 by weight of the pigment solids improves ink receptivity and allows adjustable control of finished paper gloss the amount of thermoset added to the pigment system is limited however preferably below about 75 by weight of the pigment solids so that the finished printing paper obtains a gardner 75 u00b0 gloss of at least about 40 at calendering pressures of less than 500 pli application_number US 89364778 A description the preferred composition of the inventive pigment system comprises a thermoplastic polymer and a thermosetting polymer applied as an emulsion or slurry of pigment system binders carriers and other additives designed for example to stabilize the emulsion or otherwise adjust its characteristics for a particular application or specific coating equipment the thermoplastic polymer component may be any of those commonly used in paper coating having a softening point or glass transition temperature of 105 u00b0 c and characterized by a spherical particle shape and particle size range of 0 03 0 5 micron suitable polymers and copolymers can be obtained from monomers of styrene vinyl chloride vinylidene chloride vinyl acetate methyl acrylate butyl acrylate other acrylate monomers butadiene copolymerized at low monomer concentrations of 15 or less acrylonitrile and the like the thermosetting pigment component.
