PHOTOSENSITIVE RESIN COMPOSITION

摘要

PURPOSE: A photo-sensitive resin composition and an adhesive film coated with the composition are provided to implement a patterning process through an exposing process and a developing process. CONSTITUTION: A photo-sensitive resin composition includes 100 parts by weight of (meta)acryl-based polymer and 0.5-10 parts by weight of a photo-polymerization initiator. A carboxylic group and a reactive double bond are arranged at the side chain of the (meta)acryl-based polymer. The acid value of the (meta)acryl-based polymer is between 65 and 180 KOH mg/g. The glass transition temperature of the (meta)acryl-based polymer is between -60 and -25 degrees Celsius. The average molecular weight of the (meta)acryl-based polymer is between 10000 and 300000.
