Abstract
(EN)
Provided are: a photocurable composition for three-dimensional molding which enables high-speed molding; a three-dimensional molded product obtained using the composition, and a method for producing a three-dimensional molded product. Provided by the present invention is a photocurable composition for three-dimensional molding, which contains a polymerizable organic compound component and which has a steady flow shear viscosity of 30,000 mPa·s or less, as measured at 25ºC using a rotary rheometer at a shear rate of 0.01-1 sec. If the photocurable composition for three-dimensional molding is irradiated with light at a radiation intensity of 1.3 mW/cm2, the value of G' is 1×106 Pa or more following initiation of photopolymerization and within a cumulative irradiation time of 4 seconds or less, the maximum value of tanδ at the gelling point or later following initiation of photopolymerization is 0.5 or more, and the gelling point is the first point at which G'=G'' following initiation of photopolymerization. G' is the shearing storage elastic modulus, G'' is the shearing loss elastic modulus and tanδ is the loss tangent, the foregoing being calculated on the basis of measurement data for a period of 30 seconds per measurement using a rotary rheometer having a parallel plate diameter φ of 10 mm and a measurement gap of 0.1 mm at a frequency of 0.1 Hz, a strain of 0.5% or less and a temperature of 25ºC.

L'invention concerne : une composition photodurcissable pour moulage tridimensionnel qui permet un moulage à grande vitesse ; un produit moulé tridimensionnel obtenu à l'aide de la composition, et un procédé de production d'un produit moulé tridimensionnel. La présente invention concerne une composition photodurcissable pour moulage tridimensionnel qui contient un composant composé organique polymérisable et qui possède une viscosité de cisaillement à écoulement constant de 30 000 mPa·s ou moins, mesurée à 25 °C à l'aide d'un rhéomètre rotatif à une vitesse de cisaillement de 0,01 à 1 seconde. Si la composition photodurcissable pour moulage tridimensionnel est exposée à de la lumière à une intensité de rayonnement de 1, 3 mW/cm2, la valeur de G' est 1×106 Pa ou plus après l'initiation de la photopolymérisation et pendant une durée d'exposition cumulée de 4 secondes ou moins, la valeur maximale de tanδ au point de gélification ou ultérieurement après l'initiation de la photopolymérisation est de 0,5 ou plus, et le point de gélification est le premier point auquel G'= G'' après l'initiation de la photopolymérisation. G' est le module élastique de stockage de cisaillement, G'' est le module élastique de perte de cisaillement et tanδ est la tangente de perte, ce qui précède étant calculé sur la base de données de mesure pendant une période de 30 secondes par mesure à l'aide d'un rhéomètre rotatif présentant un diamètre de plaque parallèle φ de 10 mm et un espace de mesure de 0,1 mm à une fréquence de 0,1 Hz, une contrainte de 0,5 % ou moins et une température de 25 °C.
