Description
105~ZSZ
This invention relates to a new and improved dielec-tric receptor sheet of the type used in electronradiography systems. A typical system which provides for the creation of X-ray images is described in Canadian Patent 984,894 of Munt7 et al, issued March 2, 1976, entitled RADIOGRAPHIC SYSTEMS
WITH XEROGRAPHIC PRINTING, and assigned to the same assignee as the present application. In such a system, an X-ray opaque gas at high pressure is utilized between electrodes in an imaging chamber to produce a photoelectric current within that chamber as a function of X-rays entering the chamber.
The current is collected on a receptor sheet placed on one of the electrodes, resulting in a latent electrostatic image on the sheet. This latent image is then made visible by developing and fixing, following conventional xerographic techniques.
There are several characteristics which the receptor sheet in an electronradiographic system should have. First, the material of the receptor exposed to the latent image charge should have sufficient resistivity to hold that charge without diffusion along the receptor surface, since diffusion results in blurring of the image. Secondly, one surface of the receptor should be conductinq. This conducting surface allows the in-;`, duced charge in the electrode to transfer to the back of the

1 receptor, thus preventing electric~l breakdown from the electrode 2 to the charge receptor as the receptor i8 removed from the imag-
3 ing chamber. Thirdly, the surface of the receptor which accepts
4 the im~ge charge should be such as to permit strong bonding of the toner to that surface. Finally, the receptor should be of suf-6 ficient rigidity to allow ease of handling by radiologists, while 7 also belng transp~rent for viewing the resultant image on light 8 boxes.
9 In the past, a plastic dielectric sheet has been used as the receptor, e. g., a polyester such a~ Mylar. However this 11 type of m~terial has only the first and last of the characteristics lZ discussed above. Coatings mu~t be applied to such plastic sheets 13 to obtain a conducting surface and to obtain a surface which 14 csuses the toner to adhere strongly. An aluminum backed poly-ester sheet has been suggested as a receptor. However this 16 material scratches easily and does not stretch, the latter being 17 a req~irement of some importance in spherical imaging chambers.
18 .~everal antistat~c agents have been utilized as a conductive 19 coating, but these are tacky and humidity sensitive and require interleaving between the receptor sheets.
21 The present invention is directed to a new and improved 22 multilayer receptor sheet which has all of the characteristics 23 discussed above and which permits optimum fixing of the toner 24 by both of the presently preferred methods, namely heat fixing and lamination. The receptor sheet of the present invention . ' ~1 3 .3 1051;~5'~
for positioning at an electrode of an imaging chamber to produce an electron-radiogram, consists essentially of a relatively thick optically transparent dielectric plastic core layer of substantially constant resistivity arranged in contiguous relation between a relatively thin optically transparent dielectric plastic image carrier layer and an an-tistatic electrical conducting layer. The image carrier layer has a substantially constant high resistivity for receiving on its exposed face an electrostatic image of charges generated externally of the sheet and retaining the charge image while in contact with the core layer and exposed to light. The antistatic electrical conducting layer has a substantially constant resistivity not more than about 10l2 ohms per square ~nit of area.
The advantages, features a~d results ~ill more fully appear in the course of the following description. The single figure of the drawing is a perspective view of a receptor sheet incorporating the presently preferred embodiment of the invention, with the thickness exaggerated for illustrative purposes.
Referring to the drawing, the receptor sheet 10 has a core layer ll bonded between an image carrier layer 12 and a conducting layer 13. The core layer ll is formed of a re-latively thick transpare~t dielectric plastic preferably in the range of 5 to lO mils thick and typically about 7 mils thic~. The image carrier layer 12 is formed of a relatively thin dielectric plastic in the order of l mil thick. The conducting layer 13 is an antistatic material. The core layer ll serves as the primary support for the receptor and has the rigidity to allow ease of handling of the finished picture while at the same time being highly transparent for ease of viewing, with the core layer preferably being about 5 to 15 _ 4 _ 1051ZS'~
times as thick as the carrier layer.
The conducting layer 13 may be transparent and fixed to the core layer 11, or may be opaque and separable from the core layer. When fixed to the core layer, the conducting layer (~ - 4a - .
1~5 1 2 ~'~
l should be relatively thin, typically in the order o~ 1/2 to 1 2 mil thick. A separable conducting layer, either op~que or 3 transparent, may be thicker, typlcally in the range of 5 to 10 4 mlls thick.
6 The core layer 11 may be a polyester plastic or a 6 polycarbonate plastic selected for its relative stiffness and 7 transparency~ The polycarbonate plastic is clearer than the 8 polyester plastic but is more flexible, and the polyester plas-g tic ls preferred. Mylar and Lexan are exa~ples of ~uitable polyester and polycarbonate plastics, respectively; of course, ll the other polyester and polycarbonate plastics are equally suitable.
12 The image carrier layer 12 is selected for excellent 13 dielectric properties and ~ood bonding to the toner used in de-14 veloping the latent electrostatic image. Prior to fixing the toner, the ~mage carrier layer should be sotened, permit~ing the toner 16 to be encapsulated or forced into the carrier during the fixing 17 process without spreading of the toner. In a typical fixing 18 ~rocess, the receptor and toner are heated and pressuxe is 19 applied, forcing the toner into the softened plastic. When the plastic cools and hardens the toner remains encapsulated, pro-21 viding excellent toner adhesion. For this process the layer 12 22 should soften at a temperature lower than that at which the toner 231 softens and lower than that at which the core layer softens. In 241 an alternative process, sometimes referred to as vapor fusing, a ~olvent is used to soften the carrier layer prlor to the appli-26 c~tion of pressure for forcing the toner into the carrler.

4 A polyethylene plastic such as is used for the prior ~ art receptor sheet ls preferred for the image carrier layer 12.
6 Alternatively, polystyrene, polyvinylchloride acetate, and poly-q ester adhesive may be utilized. Polystyrene has prop~rties 8 similar to that of polyethylene but is somewhat more brittle.
- Polyvinylchloride acetate and polyester adhesive have lower melting points than the polyester and polycarbonate preferred 11 for the core layer 11.
12 In an alternative fixing process, another plastic 13 sheet is lamina~ed onto the receptor sheet with the toner thereon.
14 In this type of fixing, the quality of the resultant radiogram is a function of the bonding of the additional plastic sheet to 16 the receptor sheet~ with polyethylene plastic ordinarily being 17 used as the ,additional laminating sheet.

1 The receptor sheet 10 compr~slng the three layers 11, 2 12, and 13 may be manufactured by laminating three ~ndividual 3 sheets bonded with a transparent adhe~ive, typically a polyester 4 adhes-ve.

A separable conduet~ng layer m~y be laminated to the 8 core layer by a peelable adhesive which should be applied in a 9 uniform layer. Desirably, the adhesive should have much greater affinity for the conducting layer than for the core layer so ll that ~pon separation, the adhesive will remain with the conduct-12 ing layer. ~

During the X-ray exposure, an electrostatic charge image is produced at the sur-16 face of the layer 12.
