X-ray labeling tape
First Claim
1. An x-ray marking tape, said x-ray marking tape comprising:
- a) an upper film, said upper film having a first top surface and a first bottom surface;
b) a lower film, said lower film having a second top surface and a second bottom surface;
c) a radiopaque emulsion, said radiopaque emulsion being disposed in a first predetermined position between said upper film and said lower film and in contact with said first bottom surface and said second top surface;
d) a writable surface disposed on a first portion of said first top surface in a second predetermined position such that said writable surface overlays said radiopaque emulsion;
e) at least one adhesive layer, said adhesive layer being disposed in a region between said upper film and said lower film and in contact with said first bottom surface and said second top surface; and
f) an adhesive coating disposed on at least one portion of one of said first top surface and said second bottom surface.

Abstract
A marking tape for transferring information written thereon to a film when the film is exposed to x-rays. The tape is a laminate of an upper film, a radiopaque emulsion, and a lower film. The top surface of the upper film is partially coated with a writable ink, and the ink coating positioned directly over the radiopaque emulsion. Pressure exerted by the user while writing on the ink surface causes the underlying emulsion to part. When the marking tape is affixed to a film cassette, x-rays penetrate the marking tape in those areas where the emulsion has been parted, the underlying film is exposed, and the information entered on the marking tape is thereby transferred to the film. The marking tape can be made in different sizes and radiopacities that can be distinguished by color-coding the writable surface.

12. A marking tape adapted to transfer information written on said marking tape to an x-ray film upon exposure of said x-ray film to x-rays, said marking tape comprising:
-
a) an upper film having a top surface and a bottom surface;
b) a lower film having an upper surface;
c) a radiopaque emulsion, said radiopaque emulsion being disposed between said upper film and said lower film in a strip along longitudinal axes of said upper film and said lower film, said strip having a first predetermined position, and said radiopaque emulsion being in contact with a first portion of said bottom surface and said upper surface;
d) a first adhesive coating, said first adhesive coating being disposed in a first longitudinal strip parallel to said strip of said radiopaque emulsion and being in contact with a second portion of each of said bottom surface and said upper surface;
e) a second adhesive coating, said second adhesive coating being disposed in a second longitudinal strip parallel to said strip of said radiopaque emulsion and said first strip and being in contact with a third portion of each of said bottom surface and said upper surface;
f) a writable surface comprising an ink coating covering a first portion of said first top surface and having a predetermined color, said writable surface being disposed on said top surface in a writable strip along said longitudinal axes of said upper tape and said lower tape in a second predetermined position such that said writable surface overlays said radiopaque emulsion; and
g) at least one adhesive strip, said adhesive strip covering a second portion of said top surface and being parallel to said writable strip. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A marking tape adapted to transfer information written thereon to a film upon exposure of said film to x-rays, said marking tape comprising:
-
a) an upper film having an adhesive top surface and a bottom surface;
b) a lower film having an upper surface;
c) a radiopaque emulsion, said radiopaque emulsion being disposed between said upper film and said lower tape in a strip along longitudinal axes of said upper film and said lower film, said strip having a predetermined position, and said radiopaque emulsion being in contact with a portion of said bottom surface and said upper surface;
d) a writable surface having a predetermined color, said writable surface covering said adhesive surface and being peelable therefrom. - View Dependent Claims (20, 21, 22, 23, 24)
