Abstract: Diazoresins derived from diphenylamine-4-diazonium salt(DDS) and 3-methoxydiphenylamine-4-diazonium salt(MDDS) with various organic anions were prepared and their thermal decomposition temperatures(T_d) were determined. The results showed that the diazoresins from MDDS exhibited higher T_d than that from DDS and the diazoresins with BHMS(3-benzoyl-4-hydroxyl-6-methoxybenzsulfonic acid), NS(2-naphthalene sulfonic acid), DBNS(4,8-dibutyl-2-naphthalene sulfonic acid) or PSS(polystyrene sulfonic acid) as anion possess higher T_d than that with DBS(dodecylbenzsulfonic acid) or SDS(dodecylsulfuric acid) as anion, but close to that with HSO₄^- as anion. The photoimaging behavior of the diazoresins with organic anion was examined.

Key words: organic anion, diazoresin, thermal decomposition
