Abstract
An azo dye represented by formula (1): wherein, R11 represents a monovalent substituent, R12 represents a hydrogen atom or a monovalent substituent, Ar1 represents a specific heterocyclic group such as a group such as a group shown below, and X represents atoms necessary to form a ring; wherein, in the heterocyclic group, R61 to R63 each independently represents a hydrogen atom or a substituent.
