    • A manufacturing an ink-receiving medium comprising the steps of providing a support, treating the support with a salt of a multivalent metal cation, and coating upon one or each side of the support at least one porous ink-receiving top layer from an aqueous coating composition consisting of non-cationic components, wherein the non-cationic components comprise a binder and anionic particles of average particle size less than 2.5 microns, wherein the ink-receiving top layer comprises at least 50% of the total solids by weight, such that the water-soluble salt of a multivalent metal cation is able to diffuse into the ink-receiving top layer, the method further comprising drying the coating and optionally calendering the coating. Also disclosed is inkjet media made from such method and a method of printing using such inkjet media.

    • A bleachable composition, including an acid photogenerator and a near-infrared radiation-absorbing dye or pigment, is utilized in a method of migration imaging to prevent unwanted absorptions. This composition can be incorporated either in the thermoplastic imaging surface layer of the imaging element, in the marking particles applied to the element, or both. Alternatively, the components of the bleachable composition can be separated with one in the thermoplastic imaging surface layer and the other in the marking particles. After the imaging element is marked and exposed with near-infrared radiation, the bleachable composition caused exposed portions of the imaging element to be bleached. If further bleaching is needed, the element can subsequently be exposed with near-ultraviolet radiation. A migration imaging method, which does not employ the bleachable composition of the present invention, wherein marking particles are magnetically attracted to the imaging element, is also provided.
    • 包含酸性光产生剂和近红外辐射吸收染料或颜料的可漂白组合物用于迁移成像方法以防止不希望的吸收。 该组合物可以并入成像元件的热塑性成像表面层,施加到元件的标记颗粒中,或两者。 或者,可漂白组合物的组分可以在热塑性成像表面层中与另一个在标记颗粒中分离。 在用近红外辐射标记和曝光成像元件之后,可漂白组合物使得成像元件的暴露部分被漂白。 如果需要进一步漂白,则随后可以用近紫外线辐射暴露元件。 还提供了不使用本发明的可漂白组合物的迁移成像方法,其中标记颗粒被磁性地吸引到成像元件。
