Abstract: The present invention relates to a positive-type photosensitive resin composition and a cured film prepared therefrom. The positive-type photosensitive resin composition comprises an acrylic copolymer having a dissolution rate to a developer in a specific range and a compound containing a phenolic hydroxyl group, so that it is possible to attain a high contrast and a high sensitivity pattern when a cured film is formed. Further, it is possible to further enhance the adhesiveness of a pattern when a half-tone, as well as a full-tone, is formed.
