摘要:
The present invention relates to a photocurable composition comprising: (a) 30-80% by weight of an epoxy-containing component (b) 5 to 65% by weight of a compound containing an oxetane ring in its molecule; (c) 1-25% by weight of a polyol having a molecular weight Mw of 2.000 or higher, (d) an antimony-free cationic photoinitiator. wherein the percent by weight is based on the total weight of the photocurable composition. The curable resin composition can be used for photocurable coatings per se and in specific for stereolithography and other such three dimensional printing applications where a 3D object is formed.
摘要:
Actinic radiation curable compositions comprising at least one actinic radiation curable, cationically polymerisable compound and at least one cationic photoinitiator, may be stabilised by the use of a stabiliser which is a complex of a Lewis acid (other than a fluorine-containing boron compound) and a Lewis base.
