To provide an aldehyde removing agent that can maintain high gas removal performance over a long period of time in the temperature and humidity range for normal life activities and can also have a reduced environmental impact. The problem is solved by using an NH group-containing compound-carrying porous metal complex or a porous metal complex including an NH group-containing organic ligand. For example, the porous metal complex includes at least one metal selected from elements belonging to Groups 2, 4, and 7 to 14 of the periodic table.

To provide a dye which has a good hue, which can form an image showing a high fastness under various using conditions and environmental conditions, and which is particularly suited for an ink, the dye is represents by formula (1):
wherein R
1
and R
2
each independently represents a monovalent group, Z represents a nitrogen atom or a carbon atom to which a hydrogen atom or a monovalent group is bonded, and M represents a hydrogen atom or a cation, provided that the dye has two azo groups.

A compound of Formula (1) or salt thereof:
wherein:
A
1
and A
2
are each independently optionally substituted aryl;
Q
1
and Q
2
are each independently an optionally substituted arylene or polycyclic heteroarylene group each comprising a phenylene ring which is para connected to the —N═N— and the —NR— groups shown in Formula (1); and
each R is independently H or a substituent;
L is a linking group containing at least one group selected from sulfonic acid, phosphonic acid, carboxylic acid and sulfonamide groups. The compounds have good ozone and light fastness are especially suitable for use in ink jet printing inks.
