    摘要： A method for stabilizing an isocyanate compound by adding 10-5000 ppm of phenol to the isocyanate compound, and also an isocyanate composition so stabilized. In the isocyanate composition stabilized by the above method, coloring due to time-dependent changes and the occurrence of turbidity through self-polymerization are both suppressed so that it shows outstanding storage stability compared with a corresponding isocyanate composition containing a conventional stabilizer.
