The present invention provides a naphthalenetetracarboxylic acid diimide derivative represented by the following general formula (1):
wherein R
1
and R
2
, which are identical or different, each represent a substituted or non-substituted alkyl group or a substituted or non-substituted aromatic hydrocarbon group; R
3
represents an alkyl group having 1 to 8 carbon atoms or an aromatic hydrocarbon group; R
4
, R
5
, R
6
and R
7
, which are identical or different, each represent a hydrogen atom, a substituted or non-substituted alkyl group, or a substituted or non-substituted aromatic hydrocarbon group; and R
1
and R
2
may be linked to form a substituted or non-substituted heterocyclic group including a nitrogen atom; with compounds where all of R
1
, R
2
and R
3
are a methyl group, and compounds where both of R
1
and R
2
are a methyl group and R
3
is a 1-octyl group being excluded.
