Abstract
(EN) Resin particles, each of which contains a polymer of a monomer mixture that contains a monofunctional (meth)acrylic acid ester monomer, a monomer represented by general formula (I) and a monomer represented by general formula (II). CH2=C(R1)-COO-(CH2CH2O)n-CO-C(R1)=CH2 (I) (In formula (I), R1 represents a hydrogen atom or a methyl group, and n represents an integer of 1-4.) CH2=C(R2)-COO-(CH2CH2O)m-CO-C(R2)=CH2 (II) (In formula (II), R2 represents a hydrogen atom or a methyl group, and m represents an integer of 5-15.) These resin particles have a volume average particle diameter of 5-50 μm, a recovery ratio of 15% or more but less than 30%, and a compressive strength (MPa) that provides a value multiplied by the volume average particle diameter (μm) within the range of 24.5-60.0.
(FR) La présente invention concerne des particules de résine, contenant chacune un polymère constitué d'un mélange de monomères contenant un monomère de type ester d'acide (méth)acrylique monofonctionnel, un monomère représenté par la formule générale (I) et un monomère représenté par la formule générale (II). CH2=C(R1)-COO-(CH2CH2O)n-CO-C(R1)=CH2 (I) (Dans la formule (I), R1 représente un atome d'hydrogène ou un groupe méthyle et n représente un nombre entier de 1 à 4) CH2=C(R2)-COO-(CH2CH2O)m-CO-C(R2)=CH2 (II) (Dans la formule (II), R2 représente un atome d'hydrogène ou un groupe méthyle et m représente un nombre entier de 5 à 15) Ces particules de résine présentent un diamètre de particule moyen en volume variant de 5 à 50 µm, un coefficient de reprise élastique supérieur ou égal à 15 %, mais inférieur à 30 %, et une résistance à la compression (MPa) dont la valeur multipliée par le diamètre de particule moyen en volume (µm) se situe dans l'intervalle de 24,5 à 60,0.
