摘要： A new paper composition comprising, a) from 15 wt. % to 70 wt. % a hiding composite comprising based on the total weight of the hiding composite, from 30 wt. % to 75 wt. % pigment particles and from 25 wt. % to 70 wt. % a thermoplastic polymer. The pigment particles are hydrophobically treated with the surface tension of the pigment particles being from 0.1 to 50 mN/m, and the surface tension difference between the pigment particles and the thermoplastic polymer being less than 40 mN/m; and b) from 30 wt. % to 85 wt. % a paper pulp. Process of making such a new paper composition.

摘要： The present invention is an above-critical coating composition comprising an aqueous dispersion of polymer particles, pigment particles, and extender particles wherein the polymer particles comprise, in a single phase and based on the weight of the polymer particles, from 35 to 79.9 weight percent structural units of vinyl acetate and from 0.1 to 6 weight percent structural units of a phosphorus acid monomer or a salt thereof, wherein the polymer particles have a particle size by dynamic light scattering of from 250 nm to 500 nm. The above-critical composition shows surprising improvements in hiding with increasing particle size of the polymer particles.
