Abstract

A compound selected from the group consisting of compounds of Formula (1) and compounds of Formula (2) or a salt thereof:

wherein:

• • A is a beta naphthyl group of formula X,

• • wherein * is the point of attachment to the azo group in Formula (1) or (2)
  • p and q are each independently 0, 1 or 2 and the sum of p+q is not zero;
  • B is optionally substituted phenylene or naphthylene;
  • n is 0 or 1; and
  • D is an optionally substituted pyrazolyl group.

The compound or salt is useful in an ink for ink jet printing. Also provided are printing processes, ink compositions and ink-jet cartridges for use in an ink-jet printer and substrates printed using an ink-jet printer.
