Adhesive composition and articles are described comprising a carrier substrate (e.g. release liner or backing) and an adhesive composition disposed on the carrier substrate. The adhesive composition comprises at least 20 wt.% of a polymer; unpolymerized cyclic olefin; and a (e.g. latent) ring opening metathesis polymerization catalyst or precatalyst thereof. The polymer may have a Tg less than 25° C. and/or may be an acrylic polymer. Also described is a method of bonding.

A camera cover is provided. The camera cover has a coating formed on a surface of the camera cover. The coating contains a urethane acrylate resin. The camera cover has a dome shape and is designed to protect an image capturing unit. A Berkovich hardness at an indenter penetration depth of 100 to 300 nm on a surface of the coating is at least 0.4 GPa.

Embodiments in accordance with the present invention encompass a composition containing a latent catalyst and a compound capable of generating a Bronsted acid with a counterion capable of coordinating and activating the latent catalyst along with one or more monomers which undergo ring open metathesis polymerization (ROMP) and one or more multi-functional crosslinkable molecules when said composition is exposed to a suitable radiation forms a three-dimensional (3D) object. The catalyst system employed therein can be sensitive to oxygen and thus inhibits polymerization in ambient atmospheric conditions. The three-dimensional objects made by this process exhibits improved mechanical properties, particularly, high 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.
