Abstract
The purpose of this study was to examine the effects of three types of commercially used hydrocolloid; CMC 7M, CMC 7L, HEC 250M and KELGIN MV on water retention and on coated paper properties. It was found that the concentration of hydrocolloid was an important factor in water retention values. Carboxyl groups were theorized to be another factor in water retention. Hydrocolloids were found to lower opacity, brightness and gloss over the blank coating. Increasing hydrocolloid levels decreased the openness of the coating. When increasing the amount of hydrocolloid the IGT pick decreased. KELGIN MV gave the highest water retention value.
