A photosensitive composition can be used to prepare negative-working photosensitive elements such as lithographic printing plates. The composition includes a first photocrosslinkable aromatic resin having photocrosslinkable groups and a number average molecular weight of at least about 1500. Also included is a mixture of a polyalkyleneglycol diacrylate and polyacrylate polymerizable monomers, a photocrosslinkable polyester, a photoinitiator, and a photosensitizer. The photosensitive resins are present at a total weight ratio to the polymerizable monomers of at least 1.5:1.
