A photosensitive resin realizes formation of a pattern having a good shape, without introducing poor compatibility between an acid generator and a photoresist primary-component polymer having an acid-dissociable group, and a photosensitive composition containing the photosensitive resin. The photosensitive resin includes a repeating unit represented by formula (1):
(wherein R1 represents a C2-C9 linear or branched divalent hydrocarbon group; each of R2 to R5 represents a hydrogen atom or a C1-C3 linear or branched hydrocarbon group; each of R6 and R7 represents an organic group, wherein R6 and R7 may together form a divalent organic group; and X−represents an anion);
at least one of a repeating unit represented by formula (2):
(wherein R8 represents a C2-C9 linear or branched hydrocarbon group) and a repeating unit represented by formula (3):
a repeating unit represented by formula (4):
optionally, a repeating unit represented by formula (5).

Block copolyesters and block copolyesterurethanes containing, in ordered or random distribution, about 15 to 50 percent of amorphous blocks and about 85 to 50 percent of crystalline or semi-crystalline blocks are highly compatible and substantially non-fugitive when blended with halogen-containing polymers, for instance PVC.
