摘要： The invention provides a method of forming a stencil for screen printing machines, comprising a screen (3) stretched in a frame and a layer (11 a, 11 b, 11 c) affixed to said screen and provided with a printing pattern, by exposing a light-sensitive film - (10) which comprises a light-sensitive layer (11) applied to a layer substrate (12), with an image corresponding to said printing pattern and then developing the light-sensitive layer of the exposed light-sensitive film, thereby to produce dark portions corresponding to portions illuminated during the exposure, said method being characterised in
(a) that the said dark portions are removed by an etching or bleaching process from the layer (11), thus leaving the substrate bare (5c, 6c) to form the pattern to be printed, the remaining layer (11 a, 11 b, 11c) forming margin lines against the desired printing pattern;
(b) that the said substrate (12) with the remaining unetched or unbleached layer, in order to form margin lines against the desired printing pattern, is placed against the screen - (3) stretched in the frame, such that the said remaining layer is caused to interact with the screen; remaining layer (11 a, 11 b, 11 c) and the screen (3) has been established, only the substrate (12) is removed; and
(d) that a stencil intended for screen printing machines and provided with a layer having a printing pattern is formed.摘要翻译： 本发明提供了一种形成丝网印刷机的模板的方法，包括：在框架中拉伸的筛网（3）和固定在所述筛网上并具有印刷图案的层（11a，11b，11c） 感光膜（10），其包括施加到层基板（12）的感光层（11），具有对应于所述印刷图案的图像，然后使曝光的感光膜的感光层显影，从而 产生对应于在曝光期间照射的部分的暗部分，所述方法的特征在于（a）通过蚀刻或漂白工艺从层（11）去除所述暗部分，从而将基板裸露（5c，6c）留下 形成要打印的图案，剩余层（11a，11b，11c）相对于期望的印刷图案形成边缘线; （b）将具有剩余的未蚀刻或未漂白层的所述衬底（12）放置在与框架中拉伸的屏幕（3）上，以便形成抵抗所需打印图案的边缘线，使得所述剩余层 导致与屏幕交互; （c）在剩余层（11a，11b，11c）与屏幕（3）之间的相互作用已经建立之后，仅去除衬底（12）; 和（d）形成用于丝网印刷机并设置有具有印刷图案的层的模版。 Ë

摘要： A process for obtaining highly stable color photographic images utilizes a silver halide photographic element comprising an essentially colorless, immobile compound which is capable of complexing with ferrous ions to form a dye. The complexing compound contains a complexing moiety which is represented by the formula:
wherein m is zero or a positive integer 1 to 3, n and p are independently 0 or 1 and represents a single or double bond. Z is R 1 -N=, O=, S-, R 1 -P=, (R 1 ) 2 P- or (R 1 ) 3 P=, and when Z is (R 1 ) 2 P-, n is 1, otherwise n is 0. R, R 2 , R 3 , R 4 , R 5 and R 6 are independently hydrogen, amino, hydroxy, mercapto, alkoxy, alkyl, aryl or a heterocyclic moiety. When R 6 is so defined, p is 1 and is a single bond. If m is 0, R 1 and R 2 , R 2 and R 3 , and R 3 and R 4 taken together can independently represent the carbon and heteroatoms necessary to complete a substituted or unsubstituted carbocyclic or heterocyclic nucleus, or if m is 1 to 3 , R 1 and R 2 , R 5 and R 6 , and R 3 and R 4 can independently represent the carbon and heteroatoms necessary to complete a substituted or unsubstituted heterocyclic nucleus. When R 5 and R 6 are so defined, p is 0 when -- is a double bond, and p is 1 when -- is a single bond.-

摘要： A recording medium for reflective readout in an optical information recording or playback system. The medium comprises a substrate such as polyethylene terephthalate or polymethyl methacrylate, an emulsion layer of silver halide material and an optional protective layer. The emulsion is exposed to a laser source to form a latent data image and is then developed to exhibit a glossy silver metallic image. Playback uses establshed systems.

摘要： An aqueous acidic etch-bleach solution comprising hydrogen peroxide, iron(III)ions and inorganic anions that form a silver salt having a solubility product not greater than 1×10 -8 determined in water at 20°C, characterized in that said solution contains in dissolved state as combination of H 2 O 2 - stabilizing agents citric acid and a polymer containing alkylene oxide units. Said combination provides a solution to the problem of producing ecologically acceptable and stable H 2 O 2 -solutions containing iron(III)ions.
The etch-bleach solution is useful for the production of coloured relief images and lithographic printing plates starting from silver images.摘要翻译： 一种包含过氧化氢，铁（III）离子和形成银盐的无机阴离子的水性酸性蚀刻 - 漂白剂溶液，所述阴离子在20℃的水中测定时具有不大于1×10 -8的溶度积，其特征在于所述溶液含有 以溶解状态作为H 2 O 2稳定剂柠檬酸和含环氧烷单元的聚合物的组合。 所述组合为产生含有铁（III）离子的生态学可接受且稳定的H 2 O 2溶液的问题提供了解决方案。 该蚀刻漂白剂溶液可用于从银图像开始制作彩色浮雕图像和平版印刷版。
