Patent ID: 8808961

Claim:
A composition comprising: any of compounds of the formula A-LG in which A represents any of residues of general formula (A-1) below and LG represents any of groups that are cleaved to generate acids of the formula A-H when acted on by an acid; and at least one of a compound that generates an acid when exposed to actinic rays or radiation and a compound that generates an acid when heated, in which each of R 20 and R 21 independently represents an organic group, provided that R 20 and R 21 may be bonded to each other to form a ring, and G represents a carbon atom, a sulfur atom or S═O, wherein the formula A-LG is represented by any of general formulae (1) (2), (3) and (5) below, in the formulae, each of R 1 to R 4 , R 7 to R 11 and R 15 to R 19 independently represents a hydrogen atom or a monovalent substituent, each of R 5 and R 6 independently represents a monovalent substituent, and A represents any of residues of the general formula (A-1).
