Abstract: Crosslinkable polymeric materials, crosslinked polymeric materials, articles containing the crosslinkable polymeric materials or crosslinked polymeric materials, and methods of making the articles and various compositions are provided. More particularly, the crosslinkable composition contains a) a first polymeric material, which has terminal dithiocarbamate or dithiocarbonate groups, b) a crosslinking composition containing a chlorinated triazine crosslinking agent and/or a crosslinking monomer having two or more ethylenically unsaturated groups, and c) a thixotropic agent containing metal oxide particles. The crosslinkable composition may be printable or dispensed. In some embodiments, the crosslinked composition is a pressure-sensitive adhesive.

Abstract: The disclosed patterned wavelength-selective material and process for making the patterned wavelength-selective material uses patterned applied adhesive and a structurally weak wavelength-selective material that includes portions that contact the adhesive and break to remain in contact with the adhesive. In one embodiment, the wavelength-selective material comprises an array of sections with cuts at least partially through a wavelength-selective film at each section secured to the adhesive. In another embodiment, the wavelength-selective film comprises a transfer stack of layers.

Abstract: Controlled radical initiators, reaction mixtures containing the controlled radical initiators and various ethylenically unsaturated monomers, polymeric materials formed from the reaction mixtures, crosslinkable compositions containing the polymeric materials, crosslinked compositions formed from the crosslinkable compositions, and articles containing the polymeric materials, the crosslinkable compositions, or the crosslinked compositions are provided. The controlled radical initiators are bis-dithiocarbamate or bis-dithiocarbonate compounds having a single carbon between the two dithiocarbamate or dithiocarbonate groups. Also attached to that single carbon is a ketone group.
