Abstract
Abstract A radiation image storage panel comprising a support and a phosphor layer provided on the support which comprises a binder and a stimulable phosphor dispersed therein, characterized in that the support part shows a deflection at a level ranging from 10 to 25 mm and the panel surface-side part containing said phosphor layer shows a deflection at a level ranging from 115 to 150 mm, said deflection being defined by a vertical distance from an imaginary plane horizontally extended from a flat board to an end of an object in the form of a sheet when the object is placed on the board, the end of which is overhung by 150 mm from the board.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
138 words
A radiation image storage panel comprising a support, a phosphor layer provided on the support which comprises a binder and a stimulable phosphor dispersed therein and a protective layer arranged on the phosphor layer, wherein the support is a polyethylene terephthalate sheet having a thickness in the range of 280 to 500 μm and shows a deflection at a level ranging from 10 to 25 mm and the phosphor layer and the protective layer in combination shows a deflection at a level ranging from 115 to 150 mm, said deflection being defined by a vertical distance from an imaginary plane horizontally extended from a flat board to an end of an object in the form of a sheet when the object is placed on the board, the end of which is overhung by 150 mm from the board.
Claim 2
Dependent Claim
138 words
A radiation image storage panel comprising a support, a phosphor layer provided on the support which comprises a binder and a stimulable phosphor dispersed therein and a protective layer arranged on the phosphor layer, wherein the support is a polyethylene terephthalate sheet having a thickness in the range of 280 to 500 μm and shows a deflection at a level ranging from 10 to 25 mm and the phosphor layer and the protective layer in combination shows a deflection at a level ranging from 115 to 150 mm, said deflection being defined by a vertical distance from an imaginary plane horizontally extended from a flat board to an end of an object in the form of a sheet when the object is placed on the board, the end of which is overhung by 150 mm from the board.
Claim 3
Dependent Claim
29 words
The radiation image storage panel as claimed in claim 1, in which the whole of said panel shows the deflection at a level ranging from 10 to 50 mm.
Claim 4
Dependent Claim
33 words
The radiation image storage panel as claimed in claim 1, in which the phosphor layer and the protective layer in combination shows the deflection at a level ranging from 125 to 150 mm.
Claim 5
Dependent Claim
25 words
The radiation image storage panel as claimed in claim 1, in which said support has a thickness in the range of 300 to 350 μm.
Claim 6
Dependent Claim
58 words
The radiation image storage panel as claimed in claim 1, in which said support is provided with a light-shielding layer on the surface facing the phosphor layer, on the surface opposite thereto, or both surfaces and a support part comprising the support and the light-shielding layer shows the deflection at a level ranging from 10 to 25 mm.
Claim 7
Dependent Claim
26 words
The radiation image storage panel as claimed in claim 1, in which said phosphor layer has a thickness in the range of 100 to 400 μm.
Claim 8
Dependent Claim
34 words
The radiation image storage panel as claimed in claim 1, in which a mixing ratio between the stimulable phosphor and the binder in the phosphor layer is in the range of 8:1 to 30:1.
Claim 9
Dependent Claim
34 words
The radiation image storage panel as claimed in claim 1, wherein said binder contained in the phosphor layer is linear polyester, polyalkyl (meth) acrylate, or a mixture of linear polyester and polyalkyl (meth) acrylate.
