Beschreibung
Zusammenfassung:	A polymer in the present invention contains a structural unit represented by the following general formula (1), where X1 is a tetravalent organic group, Z1 is a divalent organic group, and "k" is an integer of 1 to 3. Thus, the present invention provides: a positive photosensitive resin composition and a negative photosensitive resin composition which exhibit favorable solvent solubility and are capable of forming a fine pattern with high resolution as a result of solubility in an aqueous alkaline solution; a polyimide-based polymer usable as a base resin for these compositions; and a patterning method and a method for forming a cured film which use the compositions.
