Polyamideimide-based film coating composition

摘要

The invention relates to a polyamideimide-based film coating composition free from any restricted substance or a substance which might possibly be a restricted one such as N-methyl pyrrolidone and N-ethyl pyrrolidone and capable of replacing a conventional coating composition using a solvent such as N-methyl pyrrolidone. The polyamideimide-based film coating composition of the present invention is a polyamideimide-based film coating composition comprising a polyamideimide resin and a solvent, the polyamideimide resin being dissolved as a binder in the solvent, wherein the solvent contains ³-butyrolactone and cyclopentanone, and a volume of ³-butyrolactone is 50% by volume or more compared to a total volume of ³-butyrolactone and cyclopentanone.
