A water base ink for ink-jet recording comprises water, self-dispersing
type carbon black, an anionic surfactant, and a nonionic surfactant. The
anionic surfactant is a surfactant represented by the formula (1) and/or
a surfactant represented by the formula (2). The nonionic surfactant is a
surfactant represented by the formula (3) or a mixture of a surfactant
represented by the formula (4) and a surfactant represented by the
formula (5). No ink discharge failure occurs, the long term stability is
excellent, and it is possible to obtain a high quality image without any
feathering.
