Abstract
Embodiments of the present disclosure include organic polymeric particles, paper coating compositions, coated paper, and methods of forming coated paper with the paper coating compositions. The embodiments of the organic polymeric particle include an organic hydrophilic polymer with a unit for hydrogen bonding, and a hollow porous structure that comprises an organic polymer that at least partially surrounds the organic hydrophilic polymer, where the hollow porous structure has a pore surface area greater than 1 percent of a total theoretical exterior surface area of the hollow porous structure and the organic hydrophilic polymer and the hollow porous structure give the organic polymeric particle a void volume fraction of 40 percent to 85 percent.
