The present invention relates to a diazonium salt represented by the following
general formula (1) and a synthesizing method thereof, as well as a recording material
using the diazonium salt.
In general formula (1), R1 represents a hydrogen atom, an alkyl group
or an aryl group. R2 represents an alkyl group or an aryl group. Each
of R3, R4, R5 and R6 independently
represents a hydrogen atom or a monovalent substituent. Here, at least one of R3,
R4, R5 and R6 represents —N2+X-.
X- represents an anion.
