(57) [Summary] [Object] To provide a photocurable resin composition having excellent alkali developability, that is, easy to develop with an alkali. Further, a photocurable resin composition which is excellent in heat resistance and adhesiveness after curing, and when used as a resist material or the like, has a good sensitivity to light and gives a clear image, and is also excellent in storage stability. Provide things. [Structure] In the photocurable resin composition, 0.01 to 20 parts by weight of a photoproton generating agent is mixed with 100 parts by weight of a polymer composed of the following structural units (A), (B) and (C). . Further, the polymer may contain the structural unit (D). In addition, a reactive diluent is added to the resin composition. [Chemical 1] [Chemical 2] [Chemical 3] -X -... (D) |
