Process for producing a fade-resistant paper

摘要

A process for producing a fade-resistant paper in which a cationic charged dye fixative is thoroughly mixed with fibers in a pulper, and a fade resistant pigment is added. To this mixture is added a three component retention system and the paper is formed on a Fourdrinier paper machine. After initial drying, the paper is treated with ethylated starch on a size press, and then finally dried.
