    • This invention relates to a one- or two-component diazo-type material with improved light stability and duplication capabilities. This is accomplished by using compounds of the general formula ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4 being the same or different, represent hydrogen, alkyl with 1 to 5 carbon atoms, R.sub.1 and R.sub.2 and/or R.sub.3 and R.sub.4 represent the alkyl groups necessary for completion of a 5- or 6-membered heterocyclic ring, wherein the ring may comprise a further hetero atom, such as N, O or S;R.sub.5, R.sub.6 being the same or different, represent hydrogen, aryl, alkyl with 1 to 4 carbon atoms;Y represents --S--, --SO--, --SO.sub.2 --; andn is 0, 1, 2, 3,which are added to the material as fading inhibitors. These compounds can be easily synthesized and are compatible with the system, having an absorption maximum below 380 nm and reduced fogging tendency. They may also be employed in the form of their hydro salts.
    • 本发明涉及具有改善的光稳定性和复制能力的单组分或双组分重氮型材料。 这可以通过使用通式(I)或其中R 1,R 2,R 3,R 4相同或不同表示氢的化合物,具有1至5个碳原子的烷基,R 1和 R2和/或R3和R4表示完成5-或6-元杂环所需的烷基,其中该环可以包含另外的杂原子,例如N,O或S; R5,R6相同或不同,代表氢,芳基,具有1至4个碳原子的烷基; Y表示-S-,-SO-,-SO 2 - ; 并且n为0,1,2,3,其作为衰减抑制剂加入到该材料中。 这些化合物可以容易地合成并且与系统相容,其吸收最大值低于380nm并减少雾化趋势。 它们也可以以其盐酸盐的形式使用。
