Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a novel polycarboxy aryl ether that has excellent heat resistance as well as alkali solubility and that is highly versatile for industrial use, and to provide a precursor of a polycarboxy aryl ether having excellent heat resistance.SOLUTION: It is found that a specific polyaryl ether exhibits excellent heat resistance as well as alkali solubility by incorporating a specific functional group. It is also found that a polycyano aryl ether as a precursor has excellent heat resistance. Particularly, as a polycarboxy aryl ether has a carboxyl group, the polycarboxy aryl ether is made alkali-soluble and expected to be used for a constituent component of a photosensitive resin composition. 【課題】本発明の目的は、優れた耐熱性を有しつつアルカリ可溶性をも有する工業的に汎用性の高い新規なポリカルボキシアリールエーテルを提供することである。また、優れた耐熱性を有するポリカルボキシアリールエーテルの前駆体を提供することである。【解決手段】特定のポリアリールエーテルについて、特定の官能基を含むことで優れた耐熱性を有しつつアルカリ可溶性を発現することを見出した。また、前駆体であるポリシアノアリールエーテルについて優れた耐熱性を有することを見出した。特に上記ポリカルボキシアリールエーテルはカルボキシル基を有するためアルカリ可溶性となり、感光性樹脂組成物の構成成分としての応用が期待できる【選択図】図１
