Title
(EN) MICROCAPSULE AND MICROCAPSULE-CONTAINING COMPOSITION
(FR) MICROCAPSULE ET COMPOSITION CONTENANT DES MICROCAPSULES
(JA) マイクロカプセル及びマイクロカプセル含有組成物
Abstract
(EN)
A microcapsule that comprises, as a shell material for a shell encapsulating a core therein, a polyurethane or polyurea having a structure derived from a tri- or higher functional isocyanate compound together with a structure derived from a bifunctional aliphatic isocyanate compound and/or a structure derived from a bifunctional aromatic isocyanate compound, wherein: in the shell material, the ratio by mass of the content of the structure moiety derived from the bifunctional isocyanate compound(s) to the content of the structure moiety derived from the trifunctional isocyanate compound is from 5/95 to 20/80; a perfume is contained as a core material; and the break deformation rate is 50% or less, and a microcapsule-containing composition.
(FR)
L'invention concerne une microcapsule qui comprend, en tant que matériau de coque pour une coque à l'intérieur de laquelle un cœur est encapsulé, un polyuréthane ou une polyurée ayant une structure dérivée d'un composé isocyanate à fonctionnalité supérieure ou égale à trois conjointement avec une structure dérivée d'un composé isocyanate aliphatique bifonctionnel et/ou une structure dérivée d'un composé isocyanate aromatique bifonctionnel : dans le matériau de coque, le rapport en masse de la teneur de la fraction de structure dérivée du ou des composés isocyanates bifonctionnels à la teneur de la fraction de structure dérivée du composé isocyanate trifonctionnel étant de 5/95 à 20/80 ; un parfum étant contenu en tant que matériau de cœur ; et le taux de déformation à la rupture étant inférieur ou égal à 50 %. L'invention concerne également une composition contenant des microcapsules.
(JA)
コアを内包するシェルのシェル材として、3官能以上のイソシアネート化合物に由来する構造と、2官能の脂肪族イソシアネート化合物に由来する構造及び2官能の芳香族イソシアネート化合物に由来する構造から選ばれる少なくとも一方の構造と、を有するポリウレタン又はポリウレアを含み、かつ、シェル材における3官能イソシアネート化合物に由来する構造部分の含有量に対する、2官能のイソシアネート化合物に由来する構造部分の含有量の比率が、質量基準で5/95~20/80であり、コア材として香料を含み、かつ、破壊変形率が50%以下であるマイクロカプセル及びマイクロカプセル含有組成物である。
