Beschreibung
Zusammenfassung:	The present invention provides: a photosensitive resin composition, which can form uniform coating films having higher coating film strength without causing surface contamination, decrease of evenness of coating films, decrease of film thickness, and coloring by decomposition in heat treatment of subsequent steps, and. Has good sensitivity of exposure. The photosensitive resin composition comprises a lactone-ring-containing polymer (A) as an essential component, wherein: the lactone-ring-containing polymer (A) is obtained by carrying out polymerization of comonomers and lactonization at the same time wherein the comonomers include a 2-(hydroxyalkyl)acrylate ester and an acidic-group-containing monomer, and the lactone-ring-containing polymer (A) is obtained by almost quantitatively carrying out lactonization of a 2-(hydroxyalkyl)acrylate ester structural unit.
