Claim:
A composition that comprises a reaction product of a compound represented by formula (1) R-Z (1) and at least one member selected from the group consisting of a polysiloxane having a structure represented by formula (S-1), a hydrolysate thereof and a condensate of the hydrolysate wherein R represents a group having an alkyl group with 4 to 20 carbon atoms, a fluoroalkyl group with 1 to 20 carbon atoms, a cyclohexyl group, a group having from 17 to 51 carbon atoms and a steroid skeleton, or a group represented by formula (2) in which d is an integer of 0 to 4 and the group represented by Z is attached to either the optionally fluorinated phenyl group or the CO— group of formula (2); Z is a —COOH group, a —OH group, a —SH group, a —NCO group, a —NHR′ group where R′ is a hydrogen atom, alkyl group having 1 to 6 carbon atoms or aryl group having 6 to 30 carbon atoms, a (meth)acryloyloxyl group or a —SO 2 Cl group; X I represents a monovalent group having an oxiranyl group, a monovalent group having an oxetanyl group, a monovalent group having a vinyl group, a monovalent group having a (meth)acryloyloxyl group, or a monovalent group having a mercapto group; and Y I represents a hydroxyl group, an alkoxyl group having 1 to 10 carbon atoms, an alkyl group having 1 to 6 carbon atoms or an aryl group having 6 to 10 carbon atoms.
