Abstract:
1. An actinic-ray- or radiation-sensitive resin composition containing (A) a compound that when exposed to actinic rays or radiation, generates an acid, (B) a resin that when acted on by an acid, increases its rate of dissolution in an alkali developer, and (C) a hydrophobic resin, characterized in that the hydrophobic resin (C) contains a repeating unit derived from any of monomers of general formula (1) below, and the hydrophobic resin (C) is contained in the composition in an amount of 0.01 to 20 mass % based on the total solids of the composition, in which R R R Rf or the plurality of Rfs when m=2 independently represent an optionally fluorinated alkylene group, an optionally fluorinated cycloalkylene group or an optionally fluorinated arylene group, A represents, a group represented by the general formula below,  in which R represents a hydrogen atom or a methyl group, B represents a single bond, an optionally fluorinated alkylene group, an optionally fluorinated cycloalkylene group or a sulfonyl group, provided that the alkylene group has carbon atoms optionally partially replaced by an oxygen atom,
