Inkjet ink having pigment colorant and two surfactants having low dynamic surface tension as follows: 0.1% to 0.8% by weight of the ink of 2,5,8,11-tetraethyl-6-dodecyn-5,8-diol ethoxylate (sold commercially as DYNOL™ 604) and 0.5 to 1.0% by weight of the ink of ethoxylated 2,4,7,9-tetramethyl-5-decyn-4,7-diol (sold commercially as SURFYNOL® 465). The inks are significantly improved in photo gloss and color gamut for the printed image on swellable and porous glossy photo media.

Glass fiber-treating agent which includes: (A) 5-95% by weight of an acetylene glycol or an ethylene oxide and / or a propylene oxide adduct of an acetylene glycol; and (B) 5-95% by weight of a silicone surfactant which may be polyoxyalkylene-modified. The glass fiber-treating agent reduces dynamic and static surface tension and contact angle. The glass fiber-treating agent provides excellent wetting, penetration, and antifoaming properties when glass fibers are treated therewith.

A water-soluble surfactant composition is provided comprising (A) a glycidyl ether-capped acetylenic diol ethoxylate and (B) a polyoxyalkylene alkyl ether having an HLB of 8-18. When compounded in inks and paper coatings, the surfactant composition exerts improved foam controlling, dispersing, wetting and penetrating capabilities, is water soluble, and complies with high-speed printing and application conditions.

A surfactant composition comprising (A) a polyether-modified silicone represented by the following average composition formula (I), (B1) water, and (C1) a water-soluble organic solvent. In formula (I), R is a hydrogen atom or an alkyl group having 1 to 5 carbon atoms, and n is an integer of 6 to 20. The composition of the present invention has excellent dispersibility, wettability, and penetrability when blended in ink, has water solubility, can cope with high-speed printing and high-speed coating, and is also suitable for environmental problems.

The invention discloses a class of high-efficiency spreading agent that promotes the complete spreading of water droplets impacting on a super-hydrophobic surface. The spreading agent is composed of an ionic single-chain surfactant and a small molecule opposite to the charge of the surfactant. For anionic surfactants, the content of surfactants is 0.25%-2.00%, and the concentration of small molecules is 0.10%-1.00%; for cationic surfactants, the content of surfactants is 0.50%-2.00%, and the concentration of small molecules The concentration is 0.25%‑1.00%. The present invention utilizes the electrostatic interaction between charged small molecules and surfactants, thereby significantly reducing the critical aggregation concentration of surfactants, balancing surface tension and dynamic surface tension, and utilizing small molecules to induce abundant aggregates formed by surfactants, The hydrodynamic properties of the solution are changed to realize the complete spreading of water droplets when they hit the superhydrophobic surface, while suppressing the ejection and sputtering behavior of water droplets.

When an image is printed with inks each containing a polymer emulsion and a film forming agent, the ejection of the inks is controlled so that the ink having a relatively low dynamic surface tension forms dots having a higher dot connectivity than the dots formed with the ink having a relatively high dynamic surface tension.

The invention belongs to the technical field of wetting agents and in particular relates to a method for producing a wetting agent. The method comprises the following steps: reacting methyl isobutyl ketone to obtain 2,6,8-trimethyl-6-hydroxy-4 nonanone, reacting the 2,6,8-trimethyl-6-hydroxy-4 nonanone to obtain 2,4,8-trimethyl-4-nonyl alcohol, and reacting the 2,4,8-trimethyl-4-nonyl alcohol to obtain a highly branched-chain nonyl alcohol derivative. The method has the beneficial effects that the wetting agent has extremely low static and dynamic surface tension, and fluidity and leveling property are promoted; the product is low-foaming and can be applied to a foam inhibition wetting agent in a waterborne system; the wetting agent is silicon-free, oil-free and non-toxic; the conversion rate of the process is high.

This invention provides water-based compositions which are essentially free of hydrocarbon solvents, particularly coating, ink, fountain solution, adhesive, agricultural and electronics cleaning compositions, manifesting reduced equilibrium and dynamic surface tension by the incorporation of a surface tension reducing amount of certain tri-alkylamides of citric acid of the structurewhere R1, R2 and R3 are independently C1 to C18 alkyl groups.
