    • Integral negative-positive patterns viewable without separation of the negative-positive components. Essential elements of such film units comprise a photosensitive system which after exposure and processing can provide a diffusion transfer image pattern, an image pattern receiving system and a reflection system integrated with the elements of the product so that after exposure and processing, the image pattern can be viewed as a reflection print. The image receiving system of the products of the present invention comprise a transparent support or dimensionally stable layer through which the image pattern can be viewed and the transparent support or layer is characterized in that a distinctive UV light absorption capability is integrated therewith. In the especially preferred products, the transparent layer or support additionally comprises a finely divided pigment dispersed therein which provides an effective anti-light piping capability without impairing to any substantial degree the transparency of the support or layer.
    • 积分负 - 阳性模式可见,无需分离负 - 阳性组分。 这种膜单元的基本要素包括光敏系统,其在曝光和处理之后可以提供扩散转印图像图案,图像图案接收系统和与产品的元件集成的反射系统,使得在曝光和处理之后,图像图案可以 被视为反射打印。 本发明的产品的图像接收系统包括透明支撑件或尺寸稳定的层,通过该层可以观看图像图案,并且透明支撑件或层的特征在于与其一体的独特的UV光吸收能力。 在特别优选的产品中,透明层或支撑体另外包含分散在其中的精细分散的颜料,其提供有效的防光管道能力,而不会显着地损害载体或层的透明度。
