PROBLEM TO BE SOLVED: To provide a method for storing an aromatic urethane solution solving the problem that in general, although urethane compound is relatively stable compared to isocyanate compound, the urethane compound is susceptible to autopolymerization or decomposition when stored in the form of a solution, therefore there has been no method for stably storing the urethane compound for a long period in the form of a solution so far. SOLUTION: The method for storing a urethane compound solution involves using 1,4-dioxane as the solvent for the solution. This method enables the urethane compound to be stably stored for a long time in the form of a solution. COPYRIGHT: (C)2004,JPO&NCIPI
