摘要:
An ink containing less than 5% inorganic compounds which comprises a liquid medium and a dye of the Formula (1):
wherein:
D¹ and D² are each independently a chromophore of the azo series; R¹, R², R³ and R⁴ are each independently H or optionally substituted alkyl; B is a labile atom or group, hydroxy, amino or an ether, thioether or amine group; and X¹ and X² are each independently H, halo, alkyl, alkoxy, acylamino, ureido, nitro, carboxy or sulpho.
The inks may be used in ink jet printing either alone or with specified xanthene dyes.

摘要:
A compound which, in the free acid form, is of the Formula (1):
wherein B is 3,4- or 3,5-dicarboxyphenyl. The compound is useful in the preparation of inks for ink jet printing of paper, on which it has high water-fastness and low bronzing.
摘要:
Anionic azo compounds which, in the free acid form, have the Formula (1): wherein :
Ar 1 and Ar 2 are each independently aryl or substituted aryl providing at least one of Ar 1 and Ar 2 has at least one substituent selected from COOH and COSH; each R 1 and R 2 is independently H, alkyl, substituted alkyl, alkenyl or substituted alkenyl; L is a divalent organic linking group; n is 0 or 1; each X independently is carbonyl or a group of the formula (2), (3) or (4):
each Z independently is NR 3 R 4 , SR 5 or OR 5 ; each Y independently is H, Cl, Z, SR 6 or OR 6 ; each E independently is CI or CN; R 3 , R 4 , R 5 and R 6 are each independently H, alkyl, substituted alkyl, alkenyl, substituted alkenyl, aryl, substituted aryl, aralkyl, substituted aralkyl or R 3 and R 4 together with the nitrogen atom to which they are attached form a 5 or 6 membered ring;
provided the compound of Formula (1) has at least as many groups selected from -COOH and -COSH as -SO 3 H groups. The compounds are useful for the preparation of inks for use in ink-jet printing.
摘要:
A compound which, in the free acid form, is of the Formula (1):
wherein
B is 3- or 4-carboxyphenyl; and X is H.
The compound is useful in the preparation of inks for ink jet printing of substrates such as paper, on which it gives highly water fast prints which show little bronzing.
