Abstract

Composition and processed that preserve and enhance the brightness and improve color of pulp or paper when applied during different stages of the papermaking process are identified. The composition and method maintains and/or enhances brightness, prevent yellowing. and enhances the performances of paper products. Used in combination with optical brighteners and/or chelants the described agents produce a synergistic effect not previously identified in the paper process.
