[0811] Compound (D) can also be constituted by arbitrarily combining the above described various basic compounds with the structure represented by formula (d-1). 

[0812] Compound (D) is especially preferably a compound having the structure represented by the following formula (F). 

[0813] So long as compound (D) is a low molecular weight compound having a group capable ofleaving by the action of an acid, compound (D) may be a compound corresponding to the above various basic compounds.

[0814] In formula (F), Ra represents a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group or an aralkyl group. When n is 2, two Ra’s may be the same with or different from each other, and two Ra’s may be bonded to each other to form a divalent heterocyclic hydrocarbon group (preferably having 20 or less carbon atoms) or derivatives thereof. 

[0815] Each Rb independently represents a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group, an aralkyl group or an alkoxyalkyl group, provided that when one or more Rb in ----C(Rb )(Rb )(Rb) are hydrogen atoms, at least one of the remaining Rb is a cyclopropyl group, a 1-alkoxy› alkyl group or an aryl group. 

[0816] At least two Rb’s may be bonded to form an alicy› clic hydrocarbon group, an aromatic hydrocarbon group, a heterocyclic hydrocarbon group or derivatives thereof. 

[0817] n represents an integer of 0 to 2, m represents an integer of 1 to 3, and n+m=3. 

[0818] In formula (F), each of the alkyl group, cycloalkyl group, ary 1 group and aralky 1 group represented by Ra and Rb may be substituted with a functional group such as hydroxyl group, cyano group, amino group, pyrrolidino group, piperi› dino group, morpholino group and oxo group, an alkoxy 

group or a halogen atom. The alkoxyalkyl group represented by Rb may be substituted in the same manner. 

[0819] As the alkyl group, cycloalkyl group, aryl group and aralkyl group (these alkyl group, cycloalkyl group, aryl group, and aralkyl group may be substituted with the above functional group, alkoxy group or halogen atom) represented by Ra and/or Rb, there are exemplified, for example: 

[0820] groups deriving from straight chain or branched alkane such as methane, ethane, propane, butane, pentane, hexane, heptanes, octane, nonane, decane, undecane, dode› cane, etc., groups obtained by substituting these groups deriv› ing from alkane with, for example, one kind or more or one group or more of a cycloalkyl group such as a cyclobutyl group, a cyclopentyl group or a cyclohexyl group, 

[0821] groups deriving from cycloalkane such as cyclobu› tane, cyclopentane, cyclohexane, cycloheptane, cyclooctane, norbornane, adamantane, noradamantane, etc., groups obtained by substituting these groups deriving from cycloal› kane with, for example, one kind or more or one group or more of a straight chain or branched alkyl group such as a methyl group, an ethyl group, an n-propyl group, an i-propyl group, an n-butyl group, a 2-methylpropyl group, a 1-meth› ylpropyl group or at-butyl group, 

[0822] groups deriving from an aromatic compound such as benzene, naphthalene, anthracene, etc., groups obtained by substituting these groups deriving from aromatic compound with, for example, one kind or more or one group or more of a straight chain or branched alkyl group such as a methyl group, an ethyl group, an n-propyl group, an i-propyl group, ann-butyl group, a 2-methylpropyl group, a 1-methylpropyl group or at-butyl group, 

[0823] groups deriving from a heterocyclic compound such as pyrrolidine, piperidine, morpholine, tetrahydrofuran, tet› rahydropyran, indole, indoline, quinoline, perhydroquino› line, indazole, benzimidazole, etc., groups obtained by sub› stituting these groups deriving from heterocyclic compound with one kind or more or one group or more of a straight chain or branched alkyl group or a group deriving from an aromatic compound, groups obtained by substituting a group deriving from straight chain or branched alkane and a group deriving from cycloalkane with one kind or more or one group or more of a group deriving from an aromatic compound such as a phenyl group, a naphthyl group, anthracenyl, etc., or groups obtained by substituting the above substituents with a func› tional group such as a hydroxyl group, a cyano group, an amino group, a pyrrolidino group, a piperidino group, a mor› pholino group or an oxiso group. 

[0824] Examples of the divalent heterocyclic hydrocarbon group (preferably having a carbon number of 1 to 20) formed by combining Ra with each other or a derivative thereof include a group derived from a heterocyclic compound such as pyrrolidine, piperidine, morpholine, 1,4,5,6-tetrahydropy› rimidine, 1,2,3,4-tetrahydroquinoline, 1,2,3,6-tetrahydropy› ridine, homopiperazine, 4-azabenzimidazole, benzotriazole, 5-azabenzotriazole, lH-1,2,3-triazole, 1,4, 7-triazacy› clononane, tetrazole, 7-azaindole, indazole, benzimidazole, imidazo[l ,2-a ]pyridine, (1 S,4S)-( + )-2,5-diazabicyclo[2.2.1] heptane, 1,5, 7-triazabicyclo[ 4.4.0]dec-5-ene, indole, indo› line, 1,2,3,4-tetrahydroquinoxaline, perhydroquinoline and 1,5,9-triazacyclododecane, and a group where the group derived from such a heterocyclic compound is substituted with one or more kinds of or one or more groups oflinear or branched alkane-derived groups, cycloalkane-derived groups, aromatic compound-derived groups, heterocyclic
