摘要: 重氮树脂作为阴图PS版的感光剂已有很多专利[1~4].它是由二苯胺-4-重氮盐或取代二苯胺-4-重氮盐与多聚甲醛在浓硫酸中缩聚制得,由于耐候性与亲油墨性差,实际应用时,需将HSO4-转换为有机负离子,如与十二烷基苯磺酸钠反应,但常导致热分解温度(Td)的下降.

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(Td) were determined. The results showed that the diazoresins from MDDS exhibited higher Td 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 Td 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
