PURPOSE: To provide a photosensitive resin plate capable of suitably being used in a display especially for braille, light in weight, low in cost, easily workable by cutting, etc., superior in reproducibility of a relief, and high in wear resistance by using a resin laminated plate having a specified hardness and dimension change rate.
CONSTITUTION: A photosensitive resin layer 31 is formed on a supporting body 10 directly or through an adhesive layer 21. The supporting body 10 is a resin laminated body formed by laminating in a multi-layer a plurality of impregnating bodies each formed by impregnating fats and fatty oils modified phenol resin or fats and fatty oils modified cresol resin. Rockwell hardness of the supporting body 10 is specified to 70 to 102 in M scale, preferably to 85 to 100. If this hardness is less than 70, heat deformation easily occurs and it becomes impractical, and if it exceeds 102, the plate becomes fragile and is easy to break in a cutting process. The dimension change rate in the lateral and longitudinal direction in the temperature range of 0-200°C of the supporting body 10 is set to 0.5% or less, preferably 0.3% or less.
