Title:
ALCOHOL-MODIFIED POLYAMIDE-IMIDE RESIN AND PROCESS FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2017/221922
Kind Code:
A1
Abstract:
Provided are: a curable resin composition which contains a polyamide-imide resin that is soluble in common solvents and can be highly easily diluted with solvents and which, although a curable resin is further contained therein, has storage stability and a long pot life; and a cured object (cured coating film) which has excellent developability.
The polyamide-imide resin is an alcohol-modified polyamide-imide resin and is produced by a process comprising: a step (1) including a step (1a) in which an isocyanurate-type polyisocyanate (a2) synthesized from an isocyanate having an aliphatic structure is mixed and reacted with tricarboxylic anhydride (a1) and thereafter the isocyanurate-type polyisocyanate (a2) is further added to and reacted with the mixture; and a step (2) in which alcohol modification is conducted.
