Base generator, reagent, organic salt, composition, method for manufacturing device, cured film and device

A curable composition comprising:

• the organic salt represented by general formula (6) or (8);
• and
• a monomer having an epoxy group or an oxetanyl group or a resin having an epoxy group or an oxetanyl group,
• where:
• A1 in the general formula (6) represents:
• a hydrogen atom;
• a substituent group having an atom of a group 16 element, an atom of a group 15 element, an atom of a group 14 element other than a carbon atom or a halogen atom;
• or a monovalent organic group;
• each of A2 to A6 in the general formulas (6) and (8), together with the oxygen atoms to which they are attached, represents:
• independently from each other, a partial structure selected from the group consisting of the general formulas (12) to (24), wherein R12 to R29 each represent an optional substituent group;
• each of E, G, M and Q represents:
• independently from each other, a substituent group having an atom of a group 15 element, an atom of a group 14 element other than a carbon atom or a halogen atom;
• or a divalent organic group;
• each of H, J, T and X represents:
• independently from each other, a hydrogen atom;
• a substituent group having an atom of a group 15 element, an atom of a group 14 element other than a carbon atom or a halogen atom;
• or a monovalent organic group;
• and
• the cations in the general formulas (6) and (8) are selected from the group consisting of an azolium cation, an imidazolium cation, a pyridazinium cation, a pyrimidinium cation, a triazinium cation and a piperazinium cation.
