Abstract: Novel polymerizable ionic liquid compounds, and polymerizable compositions are described. The compositions comprise an acid functional monomer or acid-functional copolymer (or conjugate base thereof), and an imidazole compound (or conjugate acid thereof). The polymerizable compositions may be cast and cured to form a coating on a substrate, the coating capable of swelling on exposure to water so as to release from that substrate.

Abstract: The disclosed patterned wavelength-selective material and process for making the patterned wavelength-selective material uses selectively located barriers to the adhesive regions. A structurally weak wavelength-selective material includes portions that contact the adhesive regions and break to remain in contact with the adhesive. The wavelength-selective material does not contact the adhesive regions covered by the barrier and is removed leaving a wavelength-selective film in a pattern at the adhesive regions.

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.
