    • 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.

    • An image carrier and a method for forming a reprographic image thereon is disclosed, said image carrier comprising a support and an opaque hydrophilic colloid layer characterized in that said opaque hydrophilic colloid layer contains at least two kinds of opacifying agents, being (a) polymeric particles consisting of hollow spherical core/sheat beads, (b) titanium dioxide of the anatase crystal modification. The image carrier can further contain an amount of common rutile titanium dioxide. In the preferred embodiment the reprographic image is a multicolour colloid pattern serving as a pre-press proof. By appropriately choosing different ratios of the respective amounts of the different opacifying agents, a set of image carriers serving as receptor materials for transferred coloured layers can be provided giving rise to different dot gain percentages in the final proof but showing essentially the same background whiteness. The support of the image carrier can be a polyolefin covered paper base or an organic polymeric resin. This polyolefin layer or polymeric resin can be opacified themselves with titanium dioxide.
    • 公开了一种用于在其上形成复印图像的图像载体和方法,所述图像载体包括支持体和不透明的亲水胶体层,其特征在于所述不透明亲水胶体层含有至少两种不透明剂,其为(a)聚合物颗粒 由中空球形芯/护套珠组成,(b)锐钛矿晶体改性的二氧化钛。 图像载体还可以含有一定量的常见的金红石型二氧化钛。 在优选实施例中,复印图像是用作预印刷证明的多色胶体图案。 通过适当选择不同不透明剂的各自量的不同比例,可以提供用作转印着色层的受体材料的一组图像载体,从而在最终证明中产生不同的增益百分比,但显示基本上相同的背景白度。 图像载体的载体可以是聚烯烃覆盖的纸基或有机聚合物树脂。 该聚烯烃层或聚合物树脂本身可以用二氧化钛混浊。
