The disclosure provides a cross-linkable polymer composition, a core layer for an information carrying card comprising such cross-linked composition, resulting information carrying card, and methods of making the same. An information carrying card includes a body defining a first cavity and a second cavity. The first cavity has a first area and the second cavity has a second area. The first cavity is continuous with the second cavity and the second area is less than the first area. A circuit element is disposed within the first cavity.

Provided herein are methods of making (meth)acrylate blocked polyurethanes with zirconium catalysts, dual cure resins containing (meth)acrylate blocked polyurethanes and zirconium catalysts, methods of using the same in additive manufacturing, and products made therefrom.

A redox curable composition, methods for manufacturing same and uses thereof are disclosed. The redox curable composition is useful as a pre-applied adhesive. The redox curable composition is solid at room temperature, may be heated for application to a substrate, and cools to form a dry-to-touch adhesive layer on said substrate, which may be activated when required by mating with another substrate and exposure to an anaerobic environment. The composition is particularly suited to manufacturing complex products, such as mobile phones, computers and circuits.
