Abstract
Disclosed is a mold-releasing agent comprising, as active ingredients, a polyfluoroalkylphosphonic acid represented by the general formula: CF(CHCF)(CFCF)(CHCH)P(O)(OH)(n: an integer of 1 to 6, a: an integer of 1 to 4, b: an integer of 1 to 3, c: an integer of 1 to 3), or a salt thereof and a polyfluoroalkylphosphonic acid oxyalkylene ester represented by the general formula: CF(CHCF)(CFCF)(CHCH)P(O)[O(RO)R'](OH)(RO: a C-Clinear or branched oxyalkylene group, R′: a hydrogen atom, a C-Calkyl group, or aralkyl group, n: an integer of 1 to 6, a: an integer of 1 to 4, b: an integer of 1 to 3, c: an integer of 1 to 3, d: an integer of 1 or 2, m: an integer of 1 to 100). This mold-releasing agent comprises, as an active ingredient, a polyfluoroalkylphosphonic acid oxyalkylene ester having a perfluoroalkyl group containing 6 or less carbon atoms, which is said to have low bioaccumulation potential, but exhibits mold release performance equivalent to that of a mold-releasing agent comprising a compound having a perfluoroalkyl group containing 8 or more carbon atoms as an active ingredient.
