| 摘要 |
<p>The present invention relates to a composition of fine crystalline acetylenic compounds containing a plurality of conjugated acetylene linkages (i.e. a polyacetylene) having thermosensitivity at a temperature greater than 80 °C and a polycarbocyanine dye or polycarboncyanine dye mixture capable of absorbing energy within the 400 to 1500 nm wavelength range; said composition, when exposed to light emissions up to 1500 nm is capable of being encoded with a latent image, which may be subsequently developed to a visual image by exposure to a source of short wavelength radiation as is transmitted by UV light, electron beam, gamma-ray, X-ray, beta-ray, neutrons, alpha-particles and the like. The invention also relates to the method of imaging the above composition and to a recording film of said composition.</p> |
