Abstract

Ultrahigh-solid coating colors were mixed containing (#1) clay, three different ground calcium carbonates of varying particle size, and a styrene-butadiene latex as a sole binder. The resulting colors demonstrated proper coating rheology and were applied to a base paper by means of a blade coater. The coated paper was then evaluated for the physical properties produced.

An effective control of binder migration and water retention without the aid of a hydrocolloid was indicated by tests made on the coated paper. The paper coated with the ultrahigh-solid coating colors also depicted desirable finished properties of brightness, opacity, pick strength, ink receptivity, and smoothness, but lacked high glow.
