摘要:
A gradient radiation image conversion sheet, comprising a protective layer a fluorescent layer and a support layer, and the transmissions of said protective layer and/or said fluorescent layer are partially changed and the dots of the print of said gradient patterns and the border between the printed area and the unprinted area are blurred. The gradient image conversion sheet has a gradation area in which the change in transmission is extremely smooth and a speed ratio which may be set in a relatively wide range, and the sheet can be produced through a mass-production system to give products of constant quality.
