The problem to be solved by the present invention is, for example, a film having a high refractive performance at a level that can be used for optical applications, excellent adhesion to various substrates, and good blocking resistance. It is to provide an aqueous urethane resin composition capable of forming a coating or the like. The present invention is an aqueous urethane resin composition containing a urethane resin (A) and an aqueous medium (B), wherein the urethane resin (A) is a polyether ester obtained by reacting an alkylene oxide adduct of an bisphenol compound and an aromatic polycarboxylic acid. It is related with the aqueous urethane resin composition obtained by making a polyol (a1-1) and polyisocyanate (a2) react. |
