Abstract

A composition is provided including a compound (A) represented by Formula (1) and a compound (B) represented by Formula (2), wherein the compound (B) is contained in an amount of 0.00002 to 0.2 parts by mass with respect to 100 parts by mass of the compound (A): (R—COO)—R—(NCO). . . (1) (in Formula (1), Ris an ethylenically unsaturated group having 2 to 7 carbon atoms; Ris an (m+n)-valent hydrocarbon group having 1 to 7 carbon atoms; and n and m are each an integer of 1 or 2) (in Formula (2), R is (—R—(OCO—R), and Rand Rare the same as those in Formula (1)).
