The present invention provides a semicarbazide composition or the like containing a semicarbazide compound (S) derived from hydrazine and an isocyanate compound (N). The semicarbazide compound (S) includes a hydrophilic functional group (a) and a structure (b) represented by formula (I). The mole ratio (b)/(a) of said structure (b) with respect to the hydrophilic functional group (a) is 0.1-10.0. La présente invention concerne une composition de semicarbazide ou similaire contenant un composé de semicarbazide (S) dérivé de l'hydrazine et un composé isocyanate (N). Le composé de semicarbazide (S) comprend un groupe fonctionnel hydrophile (a) et une structure (b) représentée par la formule (I). Le rapport molaire (b)/(a) de ladite structure (b) par rapport au groupe fonctionnel hydrophile (a) est compris entre 0,1 et 10,0. 本発明は、イソシアネート化合物（Ｎ）とヒドラジンとから誘導されるセミカルバジド化合物（Ｓ）を含む組成物であって、前記セミカルバジド化合物（Ｓ）が親水性官能基（ａ）と、以下の式（Ｉ）で表される構造（ｂ）と、を含み、前記親水性官能基（ａ）に対する前記構造（ｂ）のモル比（ｂ）／（ａ）が０．１以上１０．０以下である、セミカルバジド組成物等を提供する。
