Abstract
A preparing method of a radiation image conversion panel comprising: forming a stimulable phosphor layer on a support while the stimulable phosphor layer being unformed on a peripheral portion around the stimulable phosphor layer on the support; and sealing the stimulable phosphor layer by superimposing a protective layer on the support formed thereon the stimulable phosphor layer while providing an adhesive agent on the peripheral portion, wherein the sealing step is conducted under a condition controlling humidity so that a moisture content of the stimulable phosphor layer is lower than the moisture content maintaining equilibrium with an atmosphere having a water partial pressure of 2.66×103 Pa.
Claims26
A preparing method of a radiation image conversion panel comprising:
- forming a stimulable phosphor layer on a support while the stimulable phosphor layer being unformed on a peripheral portion around the stimulable phosphor layer on the support;
- and
- sealing the stimulable phosphor layer by superimposing a protective layer on the support formed thereon the stimulable phosphor layer while providing an adhesive agent on the peripheral portion,
- wherein the sealing step is conducted under a condition controlling humidity so that a moisture content of the stimulable phosphor layer is lower than the moisture content maintaining equilibrium with an atmosphere having a water partial pressure of 2.66×103 Pa.
A preparing method of a radiation image conversion panel comprising:
- forming a stimulable phosphor layer on a support while the stimulable phosphor layer being unformed on a peripheral portion around the stimulable phosphor layer on the support;
- fixing a spacer on the peripheral portion by utilizing an adhesive agent so as to surround the stimulable phosphor layer;
- and
- sealing the stimulable phosphor layer by superimposing a protective layer on the spacer while providing an adhesive agent on the spacer,
- wherein the sealing step is conducted under a condition controlling humidity so that a moisture content of the stimulable phosphor layer is lower than the moisture content maintaining equilibrium with an atmosphere having a water partial pressure of 2.66×103 Pa.
A preparing method of a radiation image conversion panel comprising:
- forming a stimulable phosphor layer on a support while the stimulable phosphor layer being unformed on a peripheral portion around the stimulable phosphor layer on the support;
- fixing a protective layer on the support by providing an adhesive agent while a part of the peripheral portion being kept un-adhered so that an open area ratio of a space including the stimulable phosphor layer is not less than 10%;
- and
- sealing the stimulable phosphor layer with the protective layer and the support by providing an adhesive agent to the un-adhered part of the peripheral portion,
- wherein the sealing step is conducted under a condition controlling humidity so that a moisture content of the stimulable phosphor layer is lower than the moisture content maintaining equilibrium with an atmosphere having a water partial pressure of 2.66×103 Pa.
A preparing method of a radiation image conversion panel comprising:
- forming a stimulable phosphor layer on a support while the stimulable phosphor layer being unformed on a peripheral portion around the stimulable phosphor layer on the support;
- fixing a spacer on the peripheral portion and fixing a protective layer on the spacer with utilizing an adhesive agent, the spacer having a notched part so that an open area ratio of a space including the stimulable phosphor layer is not less than 10%;
- and
- sealing the stimulable phosphor layer by closing the notched part of the spacer,
- wherein the sealing step is conducted under a condition controlling humidity so that a moisture content of the stimulable phosphor layer is lower than the moisture content maintaining equilibrium with an atmosphere having a water partial pressure of 2.66×103 Pa.
