    摘要: An aluminum alloy plate for lithographic printing that is capable of obtaining a lithographic printing plate support which is free from appearance defects and has a uniform surface after electrolytic graining treatment and of obtaining a lithographic printing plate having a long press life and an excellent scumming resistance is provided. The aluminum alloy plate for a lithographic printing plate is obtained by continuous casting in which an aluminum alloy melt is fed through a melt feed nozzle between a pair of cooling rollers and rolled as it is being solidified by the pair of cooling rollers, wherein the aluminum alloy plate contains 0.10 to 0.20 wt % of silicon and 0.10 to 0.40 wt % of iron, and wherein the aluminum alloy plate contains in solid solution 200 to 600 ppm of silicon and not more than 250 ppm of iron.

    摘要: 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.
