摘要： Visible image-shaped regions of colloid material in a thin layer are transferred from a temporary support to a permanent support by means of a chemically hardenable adhesive applied as a liquid coating between the colloid material to be transferred and the permanent support and allowed to harden so that the temporary support can be peeled away. The visible image-shaped regions of the colloid material can form part of an overall layer or the non-image portions of such layer can be removed in advance. A preferred colloid layer is constituted of solid hydrophobic thermoplastic polymer particles dispersed in a hydrophilic binder in a weight ratio greater than 1:1 and a preferred hardenable adhesive is an epoxy resin in liquid state having a viscosity of 8,000 to 20,000 cp. which is applied to at least the pattern on the temporary support carrying the colloid layer thereon and permeates the colloid layer so that upon hardening of such resin, improved resistance to wear, humidity and heat is imparted to the colloid.
摘要翻译：在薄层中的胶体材料的可见图像形状区域通过化学可硬化粘合剂从临时支撑体转移到永久性支撑体，该粘合剂作为待转移的胶体材料与永久性支撑体之间的液体涂层施加，并允许其硬化临时支持可以剥离。胶体材料的可见图像区域可以形成整个层的一部分，或者可以预先去除这种层的非图像部分。优选的胶体层由分散在亲水性粘合剂中的以大于1:1的重量比分散的固体疏水性热塑性聚合物颗粒构成，优选的可硬化粘合剂是具有8,000至20,000cp粘度的液态环氧树脂。其至少应用于携带胶体层的临时载体上的图案并渗透胶体层，使得在这种树脂硬化时，赋予胶体更好的耐磨性，湿度和热性。

摘要： A heat-sensitive recording material of the type covered by U.S. Pat. No. 3,476,937 and including a recording layer formed of a dispersion of solid hydrophobic thermoplastic polymer particles in a water-soluble hydrophilic binder is modified to include a diffusion-resistant colorant material and a visible finely divided material absorbing radiation and converting the same into heat, such material being either chemically bleachable or soluble in an aqueous liquid. The resultant heat-sensitive material is exposed to radiation pattern and then contacted with at least one liquid to bleach or dissolve the radiation absorbing and converting material and to remove by washing the water-soluble portions of the recording layer, the portions corresponding to the radiation pattern having been rendered water-insoluble by the exposure step but remain water-permeable to permit the radiation absorbing and converting material to be bleached or dissolved by penetration of the liquid.

摘要： As a binder for pigment, e.g. baryta layers in photographic materials, about 0-75 percent of a conventional protein binder, e.g. gelatin, casein or zein, and about 100-25 percent of a latex of a graft copolymer of 80-99.5 percent of a C2-8 alkyl acrylate and 0.5-20 percent acrylonitrile, which latex is obtained by emulsion polymerization of such monomers in the presence of 5-15 percent of PVP and 0.5-2 percent of an anionic surface active emulsifying agent. The binder is used in an amount equal to about 5-25 percent of the pigment. All percentages are by weight and those of the PVP and surface-active agent are with respect to the total weight of monomers present.

摘要： A direct-positive photographic silver halide emulsion for use in a solarization technique comprising a light-sensitive silver halide which has been fogged by light or chemical means and includes a spectrally sensitizing methine dye of the 2phenylindole type in combination with a desensitizing nitrostyryl or nitrobenzylidene dye is described. In contrast to a directpositive photographic silver halide emulsion containing only the 2-phenylindole type dye or nitrostyryl or nitrobenzylidene dye, the combination provides improved stability on storage, lower minimum densities, and increased total speed.
