Abstract
Disclosed is a coloring material, comprising a plurality of organic basic skeletons each performing an acceptor function, and a donor substituent serving to connect two organic basic skeletons, wherein color is developed by the intramolecular electron migration between the substituent and the basic skeleton.
Claims15
A coloring material comprising:
- a plurality of organic basic skeletons each performing an acceptor function;
- and
- a donor substituent serving to connect two organic basic skeletons,
- wherein color is developed by the intramolecular electron migration between said substituent and said basic skeleton, wherein said coloring material has a chemical structure represented by general formula (1) given below:
- wherein each of R1, R2 and R3, which may be the same or different, is at least one of hydrogen and an alkyl group, each of X1 and X2, which may be the same or different, is selected from the group consisting of S, O, NH and Se, and Z is at least one of hydrogen and an alkyl group.
