    • This invention involves the production of sound tracks for motion picture film. Prior motion picture film sound tracks could not overlap the photographic image and were placed on the edge of the film, nor were they digitally coded to produce high fidelity. The motion picture film of the invention has a plurality of digitally coded sound track images which overlay at least a portion of the visible image (13, 14) area of the film and are colorless and transparent to visible light, but fluoresce when exposed to ultraviolet light. An electrostatic imaging process using a fluorescent toner which may be a polymer having covalently bonded 3-phenyl-7[amido or imido]-coumarin, certain substituted stilbenes or N-alkyl-4-aminophthalimides is used to form the sound track image.
    • 本发明涉及制作电影胶片的声轨。 先前的电影胶片声音不能与摄影图像重叠,并且被放置在胶片的边缘上,也没有数字编码以产生高保真度。 本发明的电影胶片具有多个数字编码声轨图像,其覆盖薄膜的可见图像(13,14)区域的至少一部分,并且对可见光是无色透明的,但当暴露于紫外线时发荧光 光。 使用可以是具有共价键合的3-苯基-7 [酰胺基或亚氨基] - 香豆素,某些取代的二苯乙烯或N-烷基-4-氨基邻苯二甲酰亚胺的聚合物的荧光调色剂的静电成像方法用于形成声轨图像。
