The invention provides a compound of Formula (1-1) or Formula (1-2) or a salt thereof:
wherein:
Ar
1
and Ar
2
each independently represent an optionally substituted aryl or heteroaryl group with the proviso that where Ar
1
is phenyl substituted with and azo group it is substituted with the azo group at the para position; R represents H, optionally substituted alkyl, or optionally substituted aryl; Q is a substituent, which may be another OH group; n is an integer from 1 to 4; m is an integer from 0 to 4, wherein each Q may be the same or different in the case where m is more than 1; and n+m is not greater than 4;
with the proviso that the compound is not one of the following compounds (i) and (ii) and the salt is not a salt thereof:
Also provided by the invention are ink compositions, printing processes, especially ink jet printing processes, printed substrates, ink cartridges and the like.
该发明提供了化合物的化学式(1-1)或(1-2)或其盐:其中:Ar1和Ar2各自独立地表示可选择取代的芳基或杂环芳基,但其中Ar1为苯基并取代有偶氮基时,偶氮基在对位取代;R代表H、可选择取代的烷基或可选择取代的芳基;Q是取代基,可能是另一个OH基团;n是1到4之间的整数;m是0到4之间的整数,其中在m大于1的情况下,每个Q可能相同也可能不同;n+m不大于4;但该化合物不是以下化合物(i)和(ii),其盐也不是这些盐。此外,该发明还提供了油墨组合物、印刷工艺,特别是喷墨印刷工艺、印刷基材、油墨盒等。
