The present invention provides n aqueous ink composition comprising a coloring component, an acetylene glycol-based surfactant, water, and a urea derivative, wherein the coloring component is a dispersion substance in which a colorant is enclosed with a dispersing polymer thereby being rendered dispersible in water, wherein the dispersing polymer comprises a hydrophobic part and a hydrophilic part, wherein at least a part of the hydrophilic part is a neutralized group obtained by neutralizing an unneutralized group constituting a part of the hydrophilic part, and wherein the neutralized groups are present within an amount range of from 20% to less than 60% in terms of molar ratio based on the sum of the neutralized groups and the unneutralized groups.
Provided is a method for producing an episulfide compound, the method including a step of thiating epoxy groups of (B) an epoxy compound by a reaction with (C) a thiating agent in the presence of (A) a polyhydric hydroxyl compound having two or more hydroxyl groups.
It is an object of the present disclosure to provide a method for efficiently and economically producing a polythioether compound by performing a ring-opening polymerization of an alicyclic episulfide compound.
The present disclosure provides a method for producing a polythioether compound, the method including performing a ring-opening polymerization of an alicyclic episulfide compound in the presence of a base. The base is preferably an amine compound. Further, the base is preferably a strong base.
