Abstract
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.
