Abstract
A photosensitive resin composition contains a co-polymer of a glycidyl (meth)acrylate or glycidyl (.alpha.-methyl)vinyl ether with a (meth)acrylic amide or ester having a quaternary ammonium salt structure, and an aromatic azide as a photosensitizer. A color filter can be prepared by coating the composition on a substrate, and exposing and developing the coated composition to form a pattern. The resultant pattern is then dyed.
