Abstract:
1. A polishing composition comprising a protection film forming agent, an anionic surfactant and a nonionic surfactant, wherein the composition has a pH of from 2 to 9 and wherein the anionic surfactant contains at least one compound represented by R1-X1-Y1, wherein R1 is an alkyl group, an alkylphenyl group or an alkenyl group, X1 is a polyoxyethylene group, a polyoxypropylene group or a poly(oxyethylene-oxypropylene) group, and Y1 is an anionic functional group, and wherein the composition is prepared so that the water contact angle of the surface of an object to be polished, after being polished by the composition, would be at most 60°, wherein the nonionic surfactant contains at least one compound represented by the chemical formula R2-X2, wherein R2 is an alkyl group, and X2 is a polyoxyethylene group, a polyoxypropylene group or a poly(oxyethylene-oxypropylene) group, and having a HLB value of from 10 to 16.
