Embodiment 1
[0061] 80 parts of (A-1) heated to 50° C. were put into a container with a blade stirrer, 10 parts of propylene glycol and 10 parts of water were slowly added, and stirred for 1 hour to obtain a surfactant composition (hereinafter referred to as called M-1).
[0062] 【Chemical 4】
[0063]
Embodiment 2~4、 comparative example 1~9
[0065] Surfactant compositions M-2 to M-13 were obtained in the same manner as in Example 1 with the compounding compositions shown in Table 1.

[0072] In addition, the measurement of each physical property was performed as follows. The results are shown in Table 2.
[0073]
[0074] The appearance of the aqueous solution and the presence or absence of insoluble matter were checked.
[0075] ○: The aqueous solution is transparent, and no insoluble matter is found
[0076] △: The aqueous solution was cloudy, but no insoluble matter was found
[0077] ×: A part of insoluble matter was found
[0078]
[0079]The dynamic surface tension at 1 Hz and 10 Hz of a 0.1% aqueous solution of the surfactant composition was measured using a bubble pressure type dynamic surface tensiometer Kruss BP-100 manufactured by KRUSS Corporation.

Embodiment 5
[0086] As the ink, after slowly adding 5 parts of Kara Bradke S170 (manufactured by Degussa Co., Ltd.) as a black pigment to 70 parts of ion-exchanged water while stirring with a blade mixer, add 1 part of surfactant composition M-1, 10 1 part polyethylene glycol (molecular weight 200), 15 parts glycerin, and after stirring for 1 hour, a black ink composition (hereinafter referred to as ℓ-1) was obtained.
[0087] Furthermore, a magenta pigment (C.I. Pigment Red 122), a cyan pigment (C.I. Pigment Blue 15:3), and a yellow pigment (C.I. Pigment Yellow 74) were used instead of the above-mentioned black pigment, and magenta (C.I. Pigment Yellow 74) was produced in the same manner as above. M), cyan (C), yellow (Y) ink.
