Patent ID: 8753792

Claim:
A positive photosensitive composition comprising: (A) a compound capable of generating an acid upon irradiation with actinic rays or radiation; (B1) a resin of which solubility in an alkali developer increases under an action of an acid; and (B2) a resin that has a group capable of decomposing under an action of an alkali to produce an alkali-soluble group, and the resin (B2) does not have a group capable of decomposing under an action of an acid, wherein the compound (A) is a compound represented by the following formulae (ZI): wherein R 201 , R 202 and R 203 each independently represents an organic group, and X— represents a sulfonate anion represented by the following formula: Rc 1 -SO 3 ⊖ wherein Rc 1 is an alkyl group in which a group at 1-position is substituted by a fluorine atom or a fluoroalkyl group and may contain a substituent other than a fluorine atom or a fluoroalkyl group; the amount added of the resin as the component (B2) is from 0.1 to 20 mass % based on the amount of the resin as the component (B1), and the resin as the component (B2) has a fluorine atom and is constituted by repeating units derived from a (meth)acrylic acid derivative only.
