    摘要： Described herein are a method for recording luminescent compositions, comprising a) providing a luminescent composition which comprises at least a first and second luminescent compound, wherein the first luminescent compound is a donor compound having a peak luminescent emission spectrum at a given wavelength, wherein the second luminescent compound is an acceptor compound having a peak absorption spectrum at a longer wavelength than the given wavelength, and wherein the emission spectrum of the donor compound at least partially overlaps the absorption spectrum of the acceptor compound; b) combining the composition with a substrate, so that at least a portion of the composition is available for exposure to a photon source; and c) embedding information at predetermined sites in the combined composition by localized exposure to a photon source, the embedding resulting in an information pattern when exposed to a luminescence deciphering device, and uses of said information pattern.

    摘要： Described herein are novel thermally reactive near-infrared absorbing acetal copolymers that undergo chemical and physical changes upon exposure to near-infrared radiation. Also described are the methods of preparation of the novel acetal copolymers starting either with vinyl-alcohol polymers or with acetal copolymers. Also described are the methods of use of the new near-infrared absorbing acetal copolymers in coatings used in lithographic offset printing plates that can be directly imaged with near-infrared laser imaging devices in computer-to-plate and digital offset printing technologies. The novel acetal copolymers are also useful in photoresist applications, rapid prototyping of printed circuit boards and chemical sensor development.
