Cartasol® Brown M2R Liquid is a product ideally suited for dyeing papers based on mechanical, recycled, and unbleached pulp. It serves as a technically advanced alternative to basic and anionic direct dyes, particularly for packaging applications. These cationic dyes have excellent substantivity and affinity for the fiber, resulting in clear backwaters in the paper mill. Additionally, they offer superior lightfastness and bleedfastness properties.
