PHOTOSENSITIVE RESIN COMPOSITION, PHOTOSENSITIVE RESIN COMPOSITION FILM AND RESIN PATTERN USING THOSE

摘要

PROBLEM TO BE SOLVED: To provide a photosensitive resin composition that is developed with a mildly alkaline aqueous solution to obtain high mechanical strength upon heating at a low temperature.

SOLUTION: The photosensitive resin composition contains (A) an alkali-soluble resin having a reactive group at a molecular chain end, (B) an organic compound having two moieties capable of linking up with the reactive group, and (C) a photosensitive agent. A photosensitive dry film and a coverlay using those are also provided.
