A carbonyl compound represented by General Formula (I),
- (in General Formula (I), R11 is an (n11+n12)-valent organic group, R12 is a monovalent organic group, n11 is an integer of 1 or more and 8 or less, n12 is an integer of 0 or more and 7 or less, and a sum of n11 and n12 is an integer of 2 or more and 8 or less).
An isocyanate composition comprising:
- with respect to a total mass of the isocyanate composition,
- 97% by mass or more of an isocyanate compound;
- and
- 2.0 ppm by mass or more and 1.0×104 ppm by mass or less of a carbonyl compound represented by General Formula (I),
