Abstract

Embodiments in accordance with the present invention encompass a two component composition containing in one component a latent organo-ruthenium carbide catalyst, and in another component a photoactive acid generator or a thermally active acid generator, and either of the components containing a mixture of photoactive compound along with one or more monomers which undergo ring open metathesis polymerization (ROMP) when said components are mixed together and exposed to a suitable radiation (or heat) to form a three-dimensional (3D) object. The three-dimensional objects so formed exhibits improved mechanical properties, particularly, high heat distortion temperature, impact strength, elongation to break, among others. Accordingly, compositions of this invention are useful as 3D inkjet materials for forming high impact strength objects of various sizes with microscale features lower than 100 microns, among various other uses.
