Provided is a non-ionic photoacid generator (A) expressed by general formula (1). R1 and R2 each independently represents an alkyl group having 1-18 carbons or a fluoroalkyl group having 1-18 carbons, an alkenyl group having 2-18 carbons, an alkynyl group having 2-18 carbons, an aryl group having 6-18 carbons, a silyl group, or the like; m and n respectively represent the number of R1s and R2s, each number being an integer from 0 to 3, and the total number (m+n) of R1s and R2s being an integer from 1 to 6. The m number of R1s and the n number of R2s may each be the same or different. R3 represents a hydrocarbon having 1-18 carbons wherein one part or all of the hydrogen may be substituted by fluorine.
The incorporation of a minor amount of a salt of pentafluorobenzene sulfonic acid to phosphate ester based functional fluids enhances the anti-erosion properties of the fluid.
