To make it possible to improve preservable stability and generate a large amount of acids from a small quantity of stimuli (information) without receiving the influence of a medium by incorporating a polymerizable monomer having one kind of a nucleophilic group and one kind of an acid generative polymerizable monomer into a composition.
The polymerizable monomer having one kind of the nucleophilic group and the polymerizable monomer having the nucleophilic group including one kind of the acid generative polymerizable monomer are expressed by formula I. In the formula I, x denotes a bivalent linkage group; Nu denotes a group having a nucleophilic site; n denotes 0 or 1 and R1, R2, R3 respectively denote hydrogen atoms or substituents. The acid generative polymerizable monomer is expressed by formula II. In the formula II, X denotes a linkage group of a bivalent group; E denotes a group having an electrophilic site; A denotes a group which generates the acids as a result of the copolymerization of the polymerizable monomer having the nucleophilic group and the acid generative polymerizable monomer expressed by the formula II and the reaction of the nucleophilic group derived from these polymerizable monomers with E; n denotes 0 or 1 and R4, R5, R6 respectively denote hydrogen atoms or substituents.
