Specific examples of the compound include a compound  having an imidazole structure ( e.g., 2-phenylbenzimidazole,  2,4,5-triphenylimidazole), a compound having a piperidine  structure [e.g., N-hydroxyethylpiperidine, bis(l,2,2,6,6-pen› tamethyl-4-piperidyl)sebacate], a compound having a pyri› dine structure (e.g., 4-dimethylaminopyridine), and a com› pound having an antipyrine structure ( e.g., antipyrine,  hydroxyantipyrine ).  [0368]  A compound having two or more ring structures is  also suitably used. Specific examples thereof include 1,5- diazabicyclo[4.3.0]non-5-ene and 1,8-diazabicyclo[5.4.0]  undec-7-ene.  [0369]  The phenoxy group-containing amine compound is  a compound where the alkyl group contained in an amine  compound has a phenoxy group at the terminal opposite the N  atom. The phenoxy group may have a substituent such as  alkyl group, alkoxy group, halogen atom, cyano group, nitro  group, carboxy group, carboxylic acid ester group, sulfonic  acid ester group, aryl group, aralkyl group, acyloxy group and  aryloxy group.  [0370]  The compound preferably has at least one oxyalky› lene chain between the phenoxy group and the nitrogen atom.  The number of oxyalkylene chains in one molecule is pref› erably from 3 to 9, more preferably from  4  to 6. Among  oxyalkylene chains, -CH$_{2}$CH$_{2}$0-is preferred.  [0371]  Specific examples of the compound include 2-[2- { 2-(2,2-dimethoxyphenoxyethoxy )ethyl }-bis-(2-methoxy- ethy  1)  ]-amine and Compounds ( C  1-1)  to ( C3-3) illustrated in  paragraph [0066] ofU.S. Patent Application Publication No.  200710224539Al.  [0372]  The phenoxy group-containing amine compound is  obtained, for example, by reacting a primary or secondary  amine having a phenoxy group with a haloalkyl ether under  heating and after adding an aqueous solution of a strong base  such as sodium hydroxide, potassium hydroxide and tet› raalkylammonium, extracting the reaction product with an  organic solvent such as ethyl acetate and chloroform. The  phenoxy group-containing amine compound may be also  obtained by reacting a primary or secondary amine with a  haloalkyl ether having a phenoxy group at the terminal under  heating and after adding an aqueous solution of a strong base  such as sodium hydroxide, potassium hydroxide and tet› raalkylammonium, extracting the reaction product with an  organic solvent such as ethyl acetate and chloroform.  [0373]  An ammonium salt is also appropriately used as the  basic compound.  [0374]  Examples of the anion of the ammonium salt  include a halide, a sulfonate, a borate and a phosphate.  Among these, a halide and a sulfonate are preferred.  [0375]  The halide is preferably chloride, bromide or iodide.  [0376]  The sulfonate is preferably an organic sulfonate  having a carbon number of  1  to 20. Examples of the organic  sulfonate include an alkylsulfonate having a carbon number  of  1  to 20 and an arylsulfonate.  [0377]  The alkyl group contained in the alkylsulfonate may  have a substituent, and examples of the substituent include a  fluorine atom, a chlorine atom, a bromine atom, an alkoxy  group, an acyl group and an aryl group. Specific examples of  the  alkylsulfonate  include  methanesulfonate,  ethane› sulfonate,  butanesulfonate,  hexanesulfonate,  octane› sulfonate, benzylsulfonate, trifluoromethanesulfonate, pen› tafluoroethanesulfonate and nonafluoro butanesulfonate.
