Abstract
A method for producing a coagulate includes: incorporating, into an aqueous urethane resin composition containing an aqueous urethane resin having an acid value of 0.01 mg KOH/g or more, a thickening agent having an oxyethylene group content of 2×10mol/g or less in an amount in the range of from 0.01 to 30 parts by mass, relative to 100 parts by mass of the aqueous urethane resin, to thicken the composition; and then coagulating the thickened composition using a coagulant containing a metal salt). A porous structure can be formed from an aqueous urethane resin composition without subjecting the composition to heating or foaming step, and therefore a coagulate having a porous structure can be stably obtained with ease.
