PROBLEM TO BE SOLVED: To obtain an active ray-curing composition good in curing compared with conventional ones and good in adhesiveness to a base material. SOLUTION: This active ray-curing composition consists of a polyester resin (A) constituted of a polyol component (a) comprising a polydiene polyol (a1) and a polycarboxylic acid component (b) and a photopolymerization initiator (B) and is used in the photosensitive layer of a photosensitive resist film, photoresist, photosensitive resin latterpress, photosensitive flexographic plate, screen plate, photo-adhesive or hard coating agent. |
