Title:
POLYAMIDE-IMIDE RESIN COMPOSITION FOR LUBRICATING COATING MATERIAL
Document Type and Number:
WIPO Patent Application WO/2014/034642
Kind Code:
A1
Abstract:
Provided is a polyamide-imide resin composition for lubricating coating materials which retains the excellent heat resistance (i.e., high glass transition temperature) and mechanical strength (i.e., high modulus) inherent in polyamide-imide resins and in which the resin has excellent solubility in the solvents including γ-butyrolactone, which is a non-amide solvent, and the dissolved state can be maintained for a long time even when the solvents are in the state of being apt to easily absorb moisture. The polyamide-imide resin composition for lubricating coating materials is characterized by containing a polyamide-imide resin that contains the repeating unit represented by formula [I] in an amount of 50 mol% or more of all the repeating units contained in the structure of the polyamide-imide resin and by containing γ-butyrolactone and 1,3-dimethyl-2-imidazolidinone as solvents.
