The present invention includes a two-layer imageable element, including: a substrate, a top layer including a first thermally imageable composition including (a) a first thermally sensitive supramolecular polymer or (b) a thermally imageable composition free of the first thermally sensitive supramolecular polymer; and disposed between the substrate and the top layer, a bottom layer including a second thermally imageable composition, which includes a second thermally sensitive supramolecular polymer. The present invention also includes a method of producing the imaged element.

Two-layer imageable element comprising thermally reversible polymers

Photosensitive compositions comprising a phenol resin having a urea bond in the main chain, planographic printing plate precursors containing the photosensitive compositions, and methods for preparing planographic printing plates using the planographic printing plate precursors are disclosed. Planographic printing plates that exhibit good durability, good exposure visual image property, and good solvent resistance; particularly superior resistance to washing oil used in UV ink printing; and superior baking property are produced.

Photosensitive composition comprising a phenol resin having a urea bond in the main chain

A photosensitive composition which comprises a resin (A) having urea bonds in its side chains and a photosensitive compound (B), wherein the resin (A) contains at least one resin selected from the group consisting of a vinyl polymer resin and a condensation polymer resin, provides a coating layer with excellent resistance to solvents and abrasion. The photosensitive composition is suitable for use in the production of planographic printing plates, integrated circuits (IC) or photomasks. A photosensitive planographic printing plate produced usig the photosensitive composition has superior press-life.
