[0423] In General Formula (PA2), 

[0424] R’$_{204 }$ and R’$_{205 }$ each independently represent an aryl group, an alkyl group, or a cycloalkyl group, and specifically, they are the same as R$_{204 }$and R$_{205 }$in Formula (ZII). 

[0425] x- represents an anion. The anion is preferably an anion represented by General Formula (dla), (d2a), (PA-Ia), (PA-Ila), or (PA-Ila). 

[0426] The compound Y is exemplified below. A com› pound obtained by appropriately modifying the combination of an anion and a cation in the following exemplified compounds may be used as the compound Y as long as it is a basic compound or ammonium salt compound whose basicity is reduced upon irradiation with actinic rays or radiation. Furthermore, similarly, a compound obtained by appropriately combining the anion exemplified in the upper part as the anion represented by General Formula (dla) and the cation in the following exemplified compounds may be used as the compound Y.
