The invention provides a photosensitive resin which is a material exhibiting excellent storage stability, affinity, miscibility, or solubility with respect to a variety of compounds, and high sensitivity and being solidified even under hydrous conditions as well as exhibiting high cure-related sensitivity and high flexibility and being uniformly solidified even under highly hydrous conditions, a photosensitive resin composition containing the resin, and a novel compound.
The photosensitive resin is a saponified poly(vinyl acetate)-based photosensitive resin having a structural unit represented by formula (1) :
(wherein R1 represents H or Me; R2 represents a linear or branched C2-C10 alkylene group; n is an integer of 1 to 3; X represents
m is an integer of 0 to 6; and Y represents an aromatic ring or a single bond).
