ABSTRACT:
A poly(imide-azomethine)copolymer that has a low linear thermal expansion coefficient and a method for producing the same copolymer are provided. Also provided are a poly(amic acid-azomethine)copolymer that is a precursor polymer of the poly(imide-azomethine)copolymer; a positive photosensitive resin composition composed of the precursor polymer and a photosensitizer; and a method for making a fine pattern of poly(imide-azomethine) copolymer from the resin composition.
