摘要： 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.
摘要翻译：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。

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 free 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，形成游离超酸。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： Certain squaric acid derivatives are useful for the thermochemical generation of acid. The squaric acid derivatives may be used in imaging media in conjunction with acid-sensitive materials which undergo a color change when contacted by the acid generated from the squaric acid derivatives. Preferably, the acid-sensitive materials undergo an irreversible color change, so that the image can be fixed by neutralizing all the acid generated with excess base, thereby preventing further color change in the image during long term storage.

摘要： Squarylium compounds of the formula: ##STR1## wherein Q.sup.1 and Q.sup.2 are each independently a pyrylium, thiopyrylium, selenopyrylium, benzpyrylium, benzthiopyrylium or benzselenopyrylium nucleus, and R.sup.1 and R.sup.2 are each independently an aliphatic or cycloaliphatic group, can be prepared by reacting a squaric acid derivative of the formula: ##STR2## with a compound of the formula Q.sup.2 CH.sub.2 R.sup.2 in the presence of a base. The derivatives of Formula II may be prepared by condensing a 2,3,4,4-tetrahalocyclobut-2-en-1-one with a compound of the formula Q.sup.1 CH.sub.2 R.sup.1 in the presence of a base to produce a compound of the formula: ##STR3## wherein Q.sup.1 and R.sup.1 are as defined above, and X represents chlorine or bromine, and hydrolyzing the compound of Formula III. Alternatively, the derivatives of Formula II may be prepared by reacting a diester, monoacid chloride monoester or diacid chloride of squaric acid with a compound of the formula Q.sup.1 CH.sub.2 R.sup.1 in the presence of a base, followed by hydrolysis of the resultant monoacid chloride or monoester derivative of the compound of Formula II to the parent compound.

摘要： Squarylium compounds of the formula: ##STR1## (in which Q.sup.1 and Q.sup.2 are each a chromophoric group having an unsaturated system conjugated with the squarylium ring and such that in the compounds of formulae Q.sup.1 CH.sub.2 R.sup.1 and Q.sup.2 CH.sub.2 R.sup.2 the methylene hydrogens are active hydrogens, R.sup.1 and R.sup.2 are each independently a hydrogen atom or an aliphatic or cycloaliphatic group, and R.sup.3 and R.sup.4 are each independently a hydrogen atom, or an aliphatic, cycloaliphatic, aromatic or heterocyclic group, or one of R.sup.3 and R.sup.4 is a hydrogen atom and the other is an organosulfonyl group, or R.sup.3 and R.sup.4 together with the intervening nitrogen atom form a cycloaliphatic or aromatic ring) are useful as near infra-red absorbers. The presence of the amino group on the squarylium ring enables minor changes in absorption wavelength to be achieved by modifications of this group, and also allows functional groups to be incorporated into the dye without changing the chromophoric groups.
