1. A compound represented by the following general formula (10):

OG Complex Work Unit Chemistry
wherein A1 represents a cyano group; R1 to R5 each independently represent a hydrogen atom or a group having a negative Hammett's σp value; at most one of R1 to R5 is a hydrogen atom; and for the R1 to R5 groups having a negative Hammett's σp value, two of the negative Hammett's σp-value groups have a different structure but have a common aromatic ring containing an atom bonding to the benzene ring of the general formula (10) in which the common aromatic ring of at least one of the two is substituted with a substituted or unsubstituted alkyl group having 1 to 20 carbon atoms or an substituted or unsubstituted aryl group having 6 to 40 carbon atoms, and a cyclic structure may be formed by the common aromatic ring in combination with the substituted or unsubstituted aryl group or the substituted or unsubstituted alkyl group.
