Paper coatings containing hydroxyethylcellulose rheology modifier and high levels of calcium carbonate pigment

摘要

A paper coating composition containing water, a binder, a high viscosity hydroxyethylcellulose polymer and a pigment, wherein the pigment comprises greater than about 80% by weight calcium carbonate pigment. Papers coated with the paper coating composition containing the high viscosity hydroxyethylcellulose polymer and calcium carbonate pigments exhibit improved water retention performance and good optical properties.
