Abstract
Abstract A composite material comprises a radiation image storage panel composed of a light-shielding substrate and a phosphor layer containing a stimulable phosphor and provided on the substrate, and a light-shielding sheet positioned on the surface on the phosphor layer side of the radiation image storage panel in a manner separable from the surface. The light-shielding sheet is made of a material interrupting stimulating rays which excite the stimulable phosphor, but permeable to a radiation passing through an object.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
65 words
A composite material for storage of a radiation image comprising: (i) a radiation image storage panel having a phosphor layer side, and comprising a light-shielding substrate and a phosphor layer containing a stimulable phosphor provided on said substrate, and (ii) a light-shielding sheet positioned on a surface on said phosphor layer side of said radiation image storage panel in a manner separable from said surface.
Claim 2
Dependent Claim
65 words
A composite material for storage of a radiation image comprising: (i) a radiation image storage panel having a phosphor layer side, and comprising a light-shielding substrate and a phosphor layer containing a stimulable phosphor provided on said substrate, and (ii) a light-shielding sheet positioned on a surface on said phosphor layer side of said radiation image storage panel in a manner separable from said surface.
Claim 3
Dependent Claim
32 words
A composite material as defined in claim 1 wherein said light-shielding sheet covers at least a part of end faces of said radiation image storage panel, and shields said part from light.
Claim 4
Dependent Claim
75 words
A composite material as defined in claim 2 wherein said radiation image storage panel has a rectangular shape, said light-shielding sheet covers a pair of the end faces of said panel opposed to each other and shields said pair of the end faces from light, and said light-shielding sheet is secured to said panel at one of said pair of the end faces so that said light-shielding sheet is not completely seperable from said panel.
Claim 5
Dependent Claim
46 words
A composite material as defined in claim 3 wherein the pair of opposite end faces other than said pair of the end faces of said rectangular radiation image storage panel covered with said light-shielding sheet are provided with end face coverings made of a light-shielding material.
Claim 6
Dependent Claim
34 words
A composite material as defined in claim 1 wherein said light-shielding sheet is provided only on the surface on the phosphor layer side of said radiation image storage panel and adhered to said surface.
Claim 7
Dependent Claim
28 words
A composite material as defined in claim 5 wherein end faces of said radiation image storage panel are provided with end face coverings made of a light-shielding material.
