US 2019/0196326 Al  26  Jun.27,2019  -continued  [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  0  ~o  ~o  ~o  o’-._/  ~o
