Image recording material and lithographic printing plate precursor

摘要

An image recording material comprising (a) an infrared ray absorber and (b) a polymer to lower a dynamic coefficient of friction to from 0.38 to 0.60, which can undergo image formation upon exposure with infrared laser; or a long-chain alkyl group-containing polymer having a reduction rate of coefficient of friction to a base polymer of from 0.5 to 0.97, the polymer being a copolymer of a long-chain alkyl group-containing monomer having 6 or more carbon atoms and a hydrophilic monomer.
