Abstract The present invention addresses the problem of providing a heat-curable composition that demonstrates superior storage stability at high temperature and superior heat-curability of a curing film surface at high temperature and high humidity, as well as a heat-curable inkjet ink that uses said heat-curable composition. This heat-curable composition includes a blocked isocyanate (A), and is characterized by also including: a compound (B) that has a functional group capable of hydrogen bonding with the blocked isocyanate (A); and a (meth)acryloyl group-including monomer (C) that does not have a functional group capable of reacting with blocked isocyanates, wherein per 100 parts by mass of the (meth)acryloyl group-including monomer (C), the heat-curable composition includes 0.1-20 parts by mass of the compound (B) and 0.1-20 parts by mass of the blocked isocyanate (A). La présente invention aborde le problème de la fourniture d'une composition thermodurcissable qui démontre une stabilité supérieure au stockage à haute température et une excellente aptitude au durcissement à chaud d'une surface de film durcissable à haute température et à humidité élevée, ainsi qu'une encre pour jet d'encre thermodurcissable qui utilise ladite composition thermodurcissable. Cette composition thermodurcissable comprend un isocyanate protégé (A), et est caractérisée en ce qu'elle comprend également : un composé (B) qui comprend un groupe fonctionnel pouvant former une liaison hydrogène avec l'isocyanate protégé (A) ; et un monomère comprenant un groupe (méth)acryloyle (C) qui ne comprend pas de groupe fonctionnel pouvant réagir avec des isocyanates protégés. Pour 100 parties en masse du monomère comprenant un groupe (méth)acryloyle (C), la composition thermodurcissable comprend de 0,1 à 20 parties en masse du composé (B) et de 0,1 à 20 parties en masse de l'isocyanate protégé (A). 本発明の課題は、高温での保存安定性と高温高湿下での硬化膜表面の熱硬化性に優れた熱硬化性組成物及びそれを用いた熱硬化性インクジェットインクを提供することである。 本発明の熱硬化性組成物は、ブロックイソシアネート(A)を含有する熱硬化性組成物であって、前記ブロックイソシアネート(A)と水素結合しうる官能基を有する化合物(B)と、ブロックイソシアネートと反応しうる官能基を有しない(メタ)アクリロイル基含有モノマー(C)とを含有し、前記(メタ)アクリロイル基含有モノマー(C)100質量部に対して、前記化合物(B)を0.1~20質量部の範囲内で含有し、かつ、前記ブロックイソシアネート(A)を0.1~20質量部の範囲内で含有することを特徴とする。
