    • The present invention provides new image forming methods. The image forming methods use a combination of a light-sensitive material and an image receiving material. The light-sensitive material comprises a support, a strippable layer and a light-sensitive polymerizable layer in order. The light-sensitive polymerizable layer contains silver halide, a reducing agent and an ethylenically unsaturated polymerizable compound or a cross-linkable polymer. The light-sensitive polymerizable layer may further contain a colorant. An image forming method using the light-sensitive polymerizable layer containing no colorant comprises an exposing step, a developing step, a toning step and a transferring step. Another image forming method using the colorant-containing light-sensitive polymerizable layer comprises an exposing step, a developing step, a removing step and a transferring step. The present invention is characterized in that an image formed on the strippable layer is entirely transferred to the image receiving material. The strippable layer has a thickness of not less than 1.0 .mu.m. A new light-sensitive material having the strippable layer is also disclosed.
    • 本发明提供了新的成像方法。 图像形成方法使用感光材料和图像接收材料的组合。 感光材料依次包括支持体,可剥离层和光敏聚合层。 光敏聚合层含有卤化银,还原剂和烯键式不饱和可聚合化合物或可交联聚合物。 光敏聚合层还可以含有着色剂。 使用不含着色剂的光敏聚合层的成像方法包括曝光步骤,显影步骤,调色步骤和转印步骤。 使用含着色剂的光敏聚合层的另一成像方法包括曝光步骤,显影步骤,去除步骤和转印步骤。 本发明的特征在于,形成在可剥离层上的图像被完全转印到图像接收材料。 可剥离层的厚度不小于1.0μm。 还公开了具有可剥离层的新的感光材料。

    • An image-receiving element for use in photographic and photothermographic diffusion transfer film units of the type wherein the image-receiving element is designed to be removed or "peeled-apart" from a photosensitive element following exposure and processing. The present image-receiving element comprises in sequence, a support, an image-receiving layer, and a strip-coat layer. The strip-coat layer serves to facilitate separation of the image-receiving layer from a photosensitive element after processing. The strip-coat layer comprises a copolymer including: 1) at least about 50% by weight of monomer units, the same or different, derived from an ethylenically unsaturated carboxylic acid or salt thereof, 2) at least about 15% by weight of monomer units of vinyl pyrrolidone, and 3) at least about 5% by weight of monomer units, the same or different, represented by the formula: ##STR1## wherein R.sub.1 of each monomer unit is independently selected from: hydrogen, a substituted or unsubstituted alkyl having 1 to 4 carbon atoms, cyano, and halogen; X of each monomer unit is independently selected from --NH-- or --O--; and R.sub.2 of each monomer unit is independently selected from a hydroxy substituted alkyl group.
    • 用于照相和光热成像漫射转印膜单元的图像接收元件,其中图像接收元件被设计成在曝光和处理之后从光敏元件去除或“剥离”。 本图像接收元件依次包括支撑体,图像接收层和带状涂层。 带涂层用于促进图像接收层与处理后的感光元件的分离。 带涂层包括共聚物,其包括:1)至少约50重量%的衍生自烯键式不饱和羧酸或其盐的相同或不同的单体单元,2)至少约15重量%的单体 乙烯基吡咯烷酮单元,和3)至少约5重量%的单体单元,相同或不同,由下式表示:其中每个单体单元的R 1独立地选自:氢,取代或未取代的烷基 具有1至4个碳原子,氰基和卤素; 每个单体单元的X独立地选自-NH-或-O-; 每个单体单元的R2独立地选自羟基取代的烷基。
