Paragraph 0172, (2021/07/02)
The invention relates to a composition excellent in stability during storage and stability during utilization, and relates to a method of producing the composition. The composition includes a compound (A) represented by general formula (1) and a compound (B) represented by general formula (2), and includes 0.00002 to 0.2 parts by mass of the compound (B) with respect to 100 parts by mass of the compound (A), [in-line-formulae](R1—COO)n—R2—(NCO)m??(1)[/in-line-formulae] [in-line-formulae](R1—COO)n—R2—(R3—R1)m??(2)[/in-line-formulae] wherein in general formulae (1) and (2), R1 is an ethylenically unsaturated group having 2 to 7 carbon atoms; R2 is a (m+n)-valent hydrocarbon group having 1 to 7 carbon atoms and optionally contains an ether group; R1 and R2 in the general formula (1) are the same as R1 and R2 in the general formula (2); in general formula (2), R3 is —NHC(═O)—; and n and m each represent an integer of one or two.
