METHODS FOR PRODUCTION OF PAPER PRODUCT WITH IMPROVED WHITENESS AND INCREASED STABILITY TO YELLOWING UNDER EFFECT OF HEAT

摘要

Compositions and processes 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 performance 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.
