PROBLEM TO BE SOLVED: To precisely reproduce the minute complex contents of an original on a negative film and to obtain high quality printed matter by laminating a photosetting resin layer, an adhesive layer, a substrate layer having a barrier performance and an elastic foam layer. SOLUTION: The material of the elastic foam layer is preferably a polyurethane or polyolefin resin having continuous and/or closed fine cells, the density of the layer is 0.1-0.6g/cm<3> and the Shore A hardness is 10-60 deg.. The substrate is, e.g. a film or sheet of one or more resins such as a polyester and nylon excellent in barrier performance. A photosensitive resin compsn. as the material of the photosetting resin layer may be any of liq. and solid compsns. if the characteristics of the resin after photosetting are suitable for the objective flexographic printing plate. The adhesive layer is preferably a polymer layer contg. at least one of resins including urethane and acrylic resins. |
