Abstract: The present invention is related to a solvent-based composition for preparing an oxygen barrier coating, comprising a binder polymer containing polar functional groups that are capable of interacting with an acidic group; an acid containing at least two reactive acidic groups; and an organic solvent. The present invention is furthermore related to a coated product comprising said oxygen-barrier coating layer, and to a method for making a coated product.

Abstract: The present invention is related to a composition for manufacturing a layer (4a, 4b, 4c) that is capable of at least partially blocking light in the UV/VIS region and is deinkable, said composition comprising a blend of a pigment and a filler. The present invention is also related to a printed article, comprising a transparent substrate (3) and on said transparent substrate (3) at least one ink layer (4a, 4b, 4c) being made from said composition. The present invention is furthermore related to a container for storing a product, preferably a food product, wherein said container comprises a transparent substrate (2) containing on its outer surface said printed article, and to a method for deinking said container.

Abstract: Silica particles, and methods of making and using silica particles are disclosed herein. In some embodiments, the silica particles are hollow, include an outer shell portion having a mesoporous structure, and have a pore volume of at least 4 cm3/g. In some embodiments, the silica particles include an outer shell portion having a mesoporous structure forming a cavity, the silica particles have an average pore diameter of 3 to 100 nm, and at least a portion of the silica particles include one or more core nanoparticles within the cavity. Silica particles as disclosed herein can be useful in a wide variety of applications such as selective separations (e.g., gas separations or purifications) based on structure.
