Abstract

Описаны композиции и способы хранения и повышения яркости и улучшения цвета пульпы или бумаги, которые применяют на разных стадиях процесса изготовления бумаги. Эти композиции и способы поддерживают и/или улучшают яркость, предотвращают пожелтение и повышают качество бумажных продуктов. При применении в комбинации с оптическими брайтнерами и/или хелантами описанные агенты создают синергический эффект, который раньше не был выявлен в процессах изготовления бумаги.
