AQUEOUS COMPOSITION OF PERFLUOROPOLYETHER PHOSPHATE AND USE OF THE SAME FOR IMPARTING OIL REPELLENCY TO PAPER

摘要

PROBLEM TO BE SOLVED: To provide an aqueous composition imparting oil repellency to a paper that passes the most severe performance test such as a tolerance test to oleic acid and a mixture of fatty acids in a wet end use. SOLUTION: The aqueous composition of (per)fluoropolyether phosphate is expressed by formula (A): T-O-[Rf-CFY-L-O]P(O)(O-Z+)(OH): and/or (B): (OH)m((O-Z+)2-mP(O)[O-L-YFC-O-Rf-CFY-L-O-P(O)(O-Z+)]m, -[O-L-YFC-O-Rf-CFY- L-O]P(O)(O-Z+)2-m(OH)mand the use of the same imparting oil repellency to a lot of papers by using the wet end method is provided.
