摘要： The present invention provides a photosensitive composition for use in producing a printing plate, and a photosensitive printing original plate laminate and a printing plate using the photosensitive composition, having durability to various types of printing inks and having excellent printability. The photosensitive composition includes at least a binder resin, a photopolymerizable monomer and a photopolymerization initiator, wherein a combination of an elastomer resin and a terpene resin is used as the binder resin. By using the elastomer resin and the terpene resin in combination, the resultant photosensitive composition has a remarkably improved durability to various types of printing inks, especially to ink components contained in such as UV curing ink or oil-based ink, or to printing inks such as alignment layer solution.
