    • A process for producing an image uses an imaging medium comprising an acid-generating layer or phase comprising a mixture of a superacid precursor, a sensitizing dye and a secondary acid generator, and a color-change layer comprising an image dye. The sensitizing dye has first and second forms, the first form having substantially greater substantial absorption in a first wavelength range than the second form. The superacid precursor is not capable, in the absence of the first form of the sensitizing dye, of being decomposed by radiation in the first wavelength range. The secondary acid generator is capable of thermal decomposition, catalyzed by superacid, to form a secondary acid. While at least part of the sensitizing dye is in its first form, the medium is imagewise exposed to radiation in the first wavelength range, thereby causing, in the exposed areas of the acid-generating layer, the formation of superacid. The medium is then heated to cause, in the exposed areas, thermal decomposition of the secondary acid generator, catalyzed by the superacid, and formation of the secondary acid. The components of the acid-generating and color-change layers or phases are then mixed so that the secondary acid causes a change in color of the image dye, and the sensitizing dye is converted to its second form. The acid-generating layer or phase desirably includes a cosensitizer which is a reducing agent less basic than the secondary acid generator.
    • 用于制备图像的方法使用包含酸产生层或包含超强酸性前体，敏化染料和次级酸产生剂的混合物的相位的成像介质和包含图像染料的变色层。 敏化染料具有第一和第二形式，第一形式在比第二形式的第一波长范围内具有显着更大的实质吸收。 在不存在第一形式的增感染料的情况下，超酸前体不能被第一波长范围内的辐射分解。 二次酸发生器能够通过超强酸催化热分解形成二次酸。 当至少部分敏化染料处于其第一种形式时，介质成像暴露于第一波长范围内的辐射，从而在酸产生层的暴露区域中形成超强酸。 然后将介质加热以在暴露的区域中引起二次酸产生剂的热分解，由超强酸催化并形成二次酸。 然后将酸产生和变色层或相的组分混合，使得次级酸引起图像染料的颜色变化，并且将敏化染料转化为其第二种形式。 酸产生层或相需要包含辅助剂，其是比次级酸发生剂更碱性的还原剂。

    • A process for producing and fixing an image uses an imaging medium comprising an acid-generating layer or phase comprising a mixture of a superacid precursor, a sensitizer and a secondary acid generator, and a color-change layer comprising an image dye. The sensitizer can absorb radiation of a sensitizer wavelength which does not, in the absence of the sensitizer, cause decomposition of the superacid precursor to form the corresponding superacid. The secondary acid generator is capable of acid-catalyzed thermal decomposition by the first acid to form a secondary acid, and the image dye undergoes a color change upon contact with the secondary acid. The medium is imagewise exposed to radiation of the sensitizer wavelength, thereby causing the sensitizer, in exposed areas, to decompose superacid precursor with formation of the fist acid. The medium is then heated to cause, in the exposed areas, acid-catalyzed thermal decomposition of the secondary acid generator and formation of the secondary acid. The components of the acid-generating and color-change layers or phases are mixed so that in exposed areas, the secondary acid causes the image dye to change color. At least the non-exposed areas, there is reacted with the superacid precursor a reactive material which irreversibly destroys the superacid precursor, thus fixing the image.
    • 用于制备和定影图像的方法使用包含酸产生层或包含超酸前体，敏化剂和次生酸发生剂的混合物的相位的成像介质和包含图像染料的变色层。 敏化剂可以吸收敏化剂波长的辐射，其在不存在敏化剂的情况下不会导致超酸前体分解形成相应的超强酸。 二次酸发生器能够通过第一种酸进行酸催化热分解以形成二次酸，并且当与次级酸接触时，图像染料发生颜色变化。 介质被成像地暴露于敏化剂波长的辐射，从而使曝光区域中的敏化剂在形成第一酸时分解超酸前体。 然后将介质加热以在暴露的区域中引起二次酸发生器的酸催化热分解和二次酸的形成。 将酸产生和变色层或相的组分混合，使得在曝光区域中，次级酸引起图像染料改变颜色。 至少未暴露的区域，与超酸前体反应是反应性材料，其不可逆地破坏超强酸前体，从而固定图像。

    • A process for producing an image uses an imaging medium comprising an acid-generating layer or phase comprising a mixture of a superacid precursor, a sensitizing dye and a secondary acid generator, and a color-change layer comprising an image dye. The sensitizing dye has a unprotonated form and a protonated form, the protonated form having substantially greater substantial absorption in a first wavelength range than the unprotonated form. The superacid precursor is capable of being decomposed to produce superacid by radiation in a second wavelength range, but is not, in the absence of the sensitizing dye, capable of being decomposed by radiation in the first wavelength range. The secondary acid generator is capable of acid-catalyzed thermal decomposition by unbuffered superacid to form a second acid. While at least part of the sensitizing dye is protonated, the medium is imagewise exposed to radiation in the first wavelength range, thereby causing, in the exposed areas of the acid-generating layer, the formation of unbuffered superacid. The medium is then heated to cause, in the exposed areas, acid-catalyzed thermal decomposition of the secondary acid generator and formation of the second acid. The components of the acid-generating and color-change layers or phases are then mixed so that the second acid causes a change in color of the image dye, and sufficient base is introduced into the unexposed areas to restore the sensitizing dye to its unprotonated form.
    • 用于制备图像的方法使用包含酸产生层或包含超强酸性前体，敏化染料和次级酸产生剂的混合物的相位的成像介质和包含图像染料的变色层。 敏化染料具有未质子化形式和质子化形式，质子化形式在第一波长范围内具有比未质子化形式显着更大的实质吸收。 超酸前体能够通过在第二波长范围内的辐射分解产生超强酸，但是在不存在敏化染料的情况下，能够在第一波长范围内被辐射分解。 二次酸发生器能够通过无缓冲的超强酸进行酸催化的热分解以形成第二酸。 当致敏染料的至少一部分被质子化时，介质被成像地暴露于第一波长范围内的辐射，从而在酸产生层的暴露区域中形成无缓冲的超强酸。 然后将介质加热以在暴露的区域中引起二次酸发生器的酸催化热分解和第二酸的形成。 然后将酸产生和变色层或相的组分混合，使得第二酸引起图像染料的颜色变化，并且将足够的碱引入未曝光区域以将致敏染料恢复至其未质子化形式 。
