Summary: | A polycarbodiimide composition is a reaction product of polyisocyanate having a primary isocyanate group and alcohols, wherein in an infrared absorption spectrum, the intensity ratio (IR CI /IR UI+U ) of absorbance IR CI at or near 2120 cm -1 due to stretching vibration of the carbodiimide group relative to absorbance IR UI+U at or near 1720 cm -1 due to stretching vibration of the uretonimine group and urethane group is 1.5 or more and 4.5 or less. |
