Abstract
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.
