| abstract |
The present invention relates to a photosensitive resin composition which is very suitable as a protective film forming material for an optical device, and is obtained by adding a polyhydric carboxylic acid anhydride compound to a conventional epoxy group-containing resin, which has adhesion to a substrate, surface hardness, transparency, heat resistance, and UV resistance. It is very suitable as a protective film forming material for optical devices because it does not generate yellowing at high temperatures while satisfying the properties of resistance, chemical resistance and water resistance. |
