The present invention provides a clear, low viscosity photocurable composition including (i) a cationically curable compound (ii) an acrylate-containing compound (iii) a polyol-conyaining mixture (iv) a cationic photoinitiator and (v) a free radical photoinitiator. The photocurable composition can be cured using rapid prototyping techniques to form opaque-white three-dimensional articles having ABS-like properties.
La présente invention porte sur une composition photodurcissable, transparente, de faible viscosité, comprenant (i) un composé durcissable de manière cationique, (ii) un composé contenant un acrylate, (iii) un mélange contenant un polyol, (iv) un photoinitiateur cationique et (v) un photoinitiateur de radicaux libres. La composition photodurcissable peut être durcie par des techniques rapides de prototypage de façon à former des articles tridimensionnels opaques-blancs ayant des propriétés analogues à l'ABS.
