AQUEOUS LIQUID COMPOSITION OF FLUORESCENT BRIGHTENER EXCELLENT IN DYEING CHARACTERISTICS

摘要

An aqueous liquid composition, characterized in that it contains an alkali salt (alkali metal salt, alkaline earth metal salt or ammonium salt) of a compound represented by the following formula (1): (1) in the form of a free acid in an amount of 10 to 40 mass %, and also contains an inorganic salt in an amount of 1.1 to 10 mass %. The aqueous liquid composition can be produced with ease by the use of a process not involving a desalting step or the like, which has been included in a conventional process, and is excellent in storage stability and excellent in the effect of enhancing whiteness.
