Problems solved by technology

However, conventional knowledge on the limitation of the number of Si in the main chain of the polyether-modified silicone structure and the number of moles of ethylene oxide added is not sufficient. In ink applications, the solubility of the ink solution may be insufficient, and the fluid properties may be insufficient. Poor, can not coat at high speed, ink characteristics can not fully exert the effect

Abstract

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.

Description

technical field [0001] The present invention relates to a water-soluble surfactant composition, and particularly relates to exhibiting excellent wettability and penetrability due to its low dynamic surface tension and low contact angle when blended in an ink, which can also be used for high-speed printing and high-speed coating, and also A water-soluble surfactant composition suitable for recent environmental problems and an ink composition containing the composition. Background technique [0002] In recent years, in the printing industry, due to environmental issues and other reasons, water-based printing has been advancing. However, in the case of the water system, the drying speed is slow, so the production speed is slower than that of the solvent system, so it has to cope with the increase in speed along with the improvement of productivity, and the performance of the ink corresponding to high-speed printing and high-speed coating is required. improve. [0003] Against...
