  A photosensitive resin composition and a method for forming patterns by using the same are disclosed. The photosensitive resin composition comprises a novolac resin (A), an ortho-naphthoquinone diazide sulfonic acid ester (B) and a ketol solvent (C). The novolac resin (A) includes a high-ortho novolac resin (A-1) that has ortho-ortho methylene bonding to all methylene bonding in a ratio of 18% to 25%, and a weight ratio (A-1)/(C) of the high-ortho novolac resin (A-1) to the ketol solvent (C) is 0.1 to 2.0, thereby exhibiting excellent temporal stability and further forming patterns with superior film to thickness uniformity and high resolution.
