※Caution

▶ When dissolved in hard water, dye may become precipitated if left for a long time after cooling. Adding sodium phosphate improves solubility and brightness.

▶ Using with positive ionic substances may cause precipitation. Do not mix with basic dye if possible.

▶ For use on waste papers, inject to beater, mixing chest and machine chest as a solvent after deinking process.

▶ Completely dissolve before injection.
