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 resin and a siloxane copolymer containing a sulfonated diazoquinone group at the terminal thereof. Thus, the film retention rate and adhesiveness can be further enhanced, while the sensitivity is maintained.
