Ra  Ra  Ra  :&  F  F  When the hydrophobic resin (HR) has a fluorine atom, the  content of fluorine atom(s) is preferably in the range of 5 to 80  mass %, more preferably 10 to 80 mass %, based on the  molecular weight of the hydrophobic resin (HR). The repeat› ing unit containing a fluorine atom preferably exists in the  hydrophobic resin (HR) in an amount of 10 to 100 mass%,  more preferably 30 to 100 mass%.  When the hydrophobic resin (HR) has a silicon atom, the  content of silicon atom( s) is preferably in the range of 2 to 50  mass %, more preferably 2 to 30 mass %, based on the  molecular weight of the hydrophobic resin (HR). The repeat› ing unit containing a silicon atom preferably exists in the  hydrophobic resin (HR) in an amount of 10 to 100 mass%,  more preferably 20 to 100 mass%.  The weight average molecular weight of the hydrophobic  resin (HR) in terms of standard polystyrene molecular weight  is preferably in the range of 1000 to 100,000, more preferably  1000 to 50,000 and still more preferably 2000 to 15,000.
