[0179] The method of synthesizing a compound that gen› erates an acid represented by Formula (I) due to the irra› diation of an actinic ray or radiation can be synthesized by a well-known synthesis method. 

[0180] In the actinic ray-sensitive or radiation-sensitive resin composition according to the embodiment of the present invention, the compound that generates the acid represented by Formula (I) due to the irradiation of an actinic ray or radiation may be used singly or two or more kinds thereof may be used in combination. Well-known acid generators other than the compound that generates an acid represented by Formula (I) by irradiation with an actinic ray or radiation may be used in combination. 

[0181] In the case where a well-known acid generator is used, for example, a photoinitiator for photocationic polym› erization, a photoinitiator for photoradical polymerization, a light-decoloring agent for coloring agents, a photochromic agent, or well-known compounds that generate an acid due
