Abstract
(EN)
Provided is a composition that is for optical stereolithography and that allows quicker completion of optical stereolithography (optical curing) to provide a stereolithographic object having a superior strength (e.g., a strength that prevents occurrence of a crack, etc., when impacted or dropped, and a strength that resists repetitive bending). The composition for optical stereolithography according to the present invention comprises (A) a diallylcycloalkane polymer having a carbon ring having 3-8 carbon atoms, (B) a radically polymerizable compound having a methacryl group and/or an acryl group, (C) a radical polymerization initiator, and (D) a sensitizer, wherein the composition contains, as (B), at least (B1) an epoxy (meth)acrylate having a methacryl group and/or an acryl group, or (B2) a dioxane (meth)acrylate having a methacryl group and/or an acryl group, and contains 0.5-10 mass% of (A), 5-43 mass% of (B1) and (B2), 20-95 mass% of (B) excluding (B1) and (B2), 0.1-5 mass% of (C), and 0.1-5 mass% of (D).

La présente invention concerne une composition qui sert à la stéréolithographie optique et qui permet un achèvement plus rapide de la stéréolithographie optique (durcissement optique) pour fournir un objet stéréolithographique présentant une résistance supérieure (une résistance qui empêche l’apparition d’une fissure, etc., lorsque ledit objet reçoit un choc ou est laissé tomber, et une résistance qui résiste à la flexion répétitive). La composition pour stéréolithographie optique selon la présente invention comprend (A) un polymère de diallylcycloalcane ayant un cycle carbone comprenant de 3 à 8 atomes de carbone, (B) un composé polymérisable par voie radicalaire comprenant un groupe méthacryle et/ou un groupe acryle, (C) un initiateur de polymérisation radicalaire, et (D) un agent de sensibilisation, la composition contenant, comme (B), au moins (B1) un (méth)acrylate époxy comprenant un groupe méthacryle et/ou un groupe acryle, ou (B2) un (méth)acrylate de dioxane comprenant un groupe méthacryle et/ou un groupe acryle, et qui contient de 0,5 à 10 % en masse de (A), de 5 à 43 % en masse de (B1) et (B2), de 20 à 95 % en masse de (B) excluant (B1) et (B2), de 0,1 à 5 % en masse de (C), et de 0,1 à 5 % en masse de (D).
