Abstract
The present invention provides a photosensitive resin composition comprising: a polyamic acid including a specific repeating unit; a heterocyclic amine compound; a (metha)acrylate-based compound including one or more double bonds between carbons; a photoinitiator; and an organic solvent, and a dry film prepared therefrom. The photosensitive resin composition can be cured at a low temperature to offer process safety and work convenience, and has excellent bending resistance, soldering heat resistance, and a property of filling the pattern, as well as excellent heat resistance and mechanical properties.
