摘要： A process for preparing a photopolymerized steric image-bearing block for printing, display, ceramic ware matrix, etc, which comprises disposing an image-bearing transparency or semitransparency or one side of a photopolymerizable composition, irradiating an actinic light to both sides thereof and removing the unexposed area to give a steric image-bearing block in which a relief portion and a substrate layer are integrally formed. There can also be obtained a steric image-bearing block having a substrate layer having partly different thickness.
