摘要： Acid can be generated by exposing a mixture of a superacid precursor and a dye to actinic radiation of a first wavelength which does not, in the absence of the dye, cause decomposition of the superacid precursor to form the corresponding superacid, thereby causing absorption of the actinic radiation and decomposition of part of the superacid precursor, with formation of a protonated product derived from the dye, then irradiating the mixture with actinic radiation of a second wavelength, thereby causing decomposition of part of the remaining superacid precursor, with formation of unbuffered superacid. Preferably, following these irradiations, the imaging medium is heated while the superacid is admixed with a secondary acid generator capable of being thermally decomposed to form a second acid, the thermal decomposition of the secondary acid generator being catalyzed by the presence of the superacid. The acid generation process may be used for imaging by bringing the superacid or second acid into contact with an acid-sensitive material which changes color on contact with acid, or the superacid may be used to trigger polymerization, depolymerization or other reactions.
摘要翻译：可以通过将超强酸前体和染料的混合物暴露于第一波长的光化辐射而产生酸，在第一波长的光化辐射下，在不存在染料的情况下，超级酸性前体不会分解形成相应的超强酸，从而引起吸收光化辐射和部分超酸前体的分解，形成衍生自染料的质子化产物，然后用第二波长的光化辐射照射混合物，从而导致部分剩余的超酸前体分解，形成无缓冲的超酸。优选地，在这些照射之后，加热成像介质，同时将超强酸与能够热分解形成第二酸的次级酸发生剂混合，二次酸产生剂的热分解由超强酸的存在催化。酸生成方法可以通过使超酸或第二酸与酸接触改变颜色的酸敏感材料接触而使用，或者超酸可用于引发聚合，解聚或其它反应。

摘要： Acid can be generated by exposing a superacid precursor to actinic radiation effective to generate superacid from the superacid precursor and heating the superacid in admixture with a secondary acid generator capable of undergoing thermal decomposition to produce a secondary acid. The superacid catalyzes decomposition of the secondary acid generator, thus increasing the quantity of strong acid present in the medium. The resultant secondary acid can be used to effect a color change in an acid-sensitive material, so providing an imaging process.

摘要： Copolymeric mordant materials containing recurring units according to the following formula are disclosed: ##STR1## In such copolymers, each of R.sup.1, R.sup.2 and R.sup.3 can independently be alkyl; substituted-alkyl; cycloalkyl; aryl; aralkyl; alkaryl; or at least two of R.sup.1, R.sup.2 and R.sup.3, together with the quaternary nitrogen atom to which they are bonded, can complete a saturated or unsaturated, substituted or unsubstituted nitrogen-containing heterocyclic ring; X is an anion; R.sup.4 is hydrogen or alkyl (e.g. methyl). The pendent "b" group contain hydrogen-bonding sites for promotion of self-associated aggregation and ring unsaturation for photocyclization and control of physical properties (e.g., water insensitivity) of the image-receiving layer. The copolymeric mordant materials can be utilized as image-receiving layers in photographic products and processes of the diffusion transfer type. The mordants are especially adapted to the production of dye images exhibiting favorable maximum density (D.sub.max) and rates of dye transfer properties.
