didecylamine, methyl octadecylamine, dimethylundecylam› ine, N,N-dimethyldodecylamine, methyl dioctadecylamine, N,N-dibutylaniline, N,N-dihexylaniline, 2,6-diisopropylani› line, and 2,4,6-tri(t-butyl)aniline. 

In addition, as the preferable basic compound represented by General Formula (BS-1), an alkyl group in which at least one R is substituted with a hydroxy group is exemplified. Specific examples thereof include triethanolamine and N,N› dihydroxyethylaniline. 

Moreover, the alkyl group as R may have an oxygen atom in the alkyl chain. That is, an oxyalkylene chain may be 

formed. The oxyalkylene chain 1s preferably ----CH$_{2}$CH$_{2}$0-. Specific examples thereof include tris (methoxyethoxyethyl)amine and a compound disclosed after line 60 of column 3 in the specification of U.S. Pat. No. 6,040, 112A. 

Among the basic compounds represented by General Formula (BS-1), examples of such the basic compounds having a hydroxyl group, an oxygen atom, or the like include the following ones.
