Title:
PRODUCTION OF POLY-O-HYDROXYAMIDE AND POLY-O-MERCAPTOAMIDE
Document Type and Number:
Japanese Patent JP3167630
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To economically obtain poly-o-hydroxyamide and poly-o- mercaptoamide, soluble in an aqueous alkaline developing agent not containing a metal ion by using a method not including a chloride and reacting a bis-o- amino(thio)phenol with a dicarboxylic acid derivative having a specific structure.
SOLUTION: These objective compounds are obtained by reacting (A) a bis-o-amino(thio)phenol with (B) a dicarboxylic acid derivative of formula: I {D is O, S or NH; R1, R2 are each independently H, F, CH3, CN or NO2, at least one group of R1, R2 is CN or NO2; R* is -(CR2)m [R is H, F, CH3 or CF3; (m) is 1-10], a group of formula II or III [A is C(CH3)2, C(CF3)2, C(CH3)(C6H5), C(CF3)(C6H5), etc.] or a group of formula IV (X is CH or N)} preferably in the presence of a basic catalyst (preferably a tertiary amine), preferably at 20-150°C. Further, as the component (B), the dicarboxylic acid ester having a nitrophenol group is preferably used.
