Rc3$_{2 }$represents a group having an alkyl group, a cycloalkyl group, an alkenyl group, a cycloalkenyl group or an aryl group. These groups may be substituted with a fluorine atom or a silicon atom. 

Lc3 represents a single bond or a divalent linking group. 

In formula (III), the alkyl group of Rc3$_{2 }$ is preferably a linear or branched alky 1 group having a carbon number of 3 to 20. 

The cycloalkyl group is preferably a cycloalkyl group hav- ing a carbon number of 3 to 20. 

The alkenyl group is preferably an alkenyl group having a carbon number of3 to 20. 

The cycloalkenyl group is preferably a cycloalkenyl group having a carbon number of 3 to 20. 

The aryl group is preferably a phenyl group or a naphthyl group, which are an aryl group having a carbon number of 6 to 20, and these groups may have a substituent. 

Rc3$_{2 }$is preferably an unsubstituted alkyl group or a fluorine atom-substituted alkyl group. 

The divalent linking group ofLc3 is preferably an alkylene group (preferably having a carbon number of 1 to 5), an oxy group, a phenylene group or an ester bond (a group repre- sented by --COO-). It is also preferred that the hydrophobic resin (HR) further contains a repeating unit represented by the following formula (CII-AB):

In formula (CII-AB), eachofRc$_{11}$’ andRc1 2 ’ independently represents a hydrogen atom, a cyano group, a halogen atom or an alkyl group. 

Zc’ represents an atomic group for forming an alicyclic structure together with two carbon atoms (C----C) to which Zc’ is bonded.
