The present invention relates to a positive-type photosensitive resin composition and a cured film prepared therefrom. The positive-type photosensitive resin composition introduces a multifunctional monomer into a positive-type photosensitive resin composition comprising a mixed binder in which a siloxane copolymer is added to an acrylic copolymer, whereby the penetration of a developer into the binder can be facilitated at the time of development of a pre-baked film to increase the solubility in the developer, thereby further enhancing the pattern developability and sensitivity. Further, a cured film prepared from the composition has excellent appearance characteristics without a rough surface of the film and a scum or the like at the bottom of the film during development.

The present invention relates to a positive-type photosensitive resin composition and a cured film prepared therefrom. The composition comprises a photoactive compound of a polymer, and/or a photoactive compound of a monomer, containing a repeat unit having a specific structure. Thus, the exposed portion (i.e., the portion exposed to light) is increased by the interaction between the binder resin (i.e., siloxane copolymer) and the photoactive compound, which increases the solubility in a developer, whereby the sensitivity can be enhanced. In addition, it is possible to form a cured film capable of achieving a high edge angle of a pattern by way of employing the photoactive compound in a proper amount.
