Abstract
A perfluoropolyether phosphate ester represented by the general formula:[CFO{CF(CF)CFO}CF(CF)CHO]PO(OH)(wherein n is an integer of 1 to 20). This compound is obtained by reacting a perfluoropolyether alcohol represented by the general formula:CFO{CF(CF)CFO}CF(CF)CHOH(wherein n is an integer of 1 to 20) with phosphorus oxychloride, and hydrolyzing the obtained compound represented by the general formula:[CFO{CF(CF)CFO}CF(CF)CHO]POCl(wherein n is an integer of 1 to 20). Moreover, the perfluoropolyether phosphate ester or a salt thereof forms a surface treatment agent comprising the perfluoropolyether phosphate ester or a salt thereof as an active ingredient.
