• and
• a curable compound:
• wherein, in the formula, Y represents an anion,
• Rcy1 to Rcy5 each independently represent a hydrogen atom or a substituent,
• at least one of Rcy1, Rcy2, Rcy3, Rcy4 or Rcy5 represents the group represented by the following Formula (1);
• wherein in Formula (1), G1 represents NRG1 or an oxygen atom, RG1 represents a hydrogen atom or a monovalent substituent, and G2 represents a monovalent substituent having a -Es′ value of 2.4 or higher as a steric parameter,
• two of Rcy1 to Rcy5 may be bonded to each other to form a ring,
• ncy1 represents an integer of 0 to 2,
• in a case where ncy1 represents 2, a plurality of Rcy4's may be the same as or different from each other and a plurality of Rcy5's may be the same as or different from each other, and
• Acy1 and Acy2 each independently represent an aryl group or a heterocyclic group.
