摘要： Photosensitizing dyes are often used in conjunction with a photoacid generator in photopolymerizable materials and in holographic recording media. Typical dyes for these materials are used in the region of the visible spectrum for wavelengths greater than about 450 run. The present invention discloses a number of new 1,4-alkynyl substituted napthalene photosensitizing dyes that have suitably low extinction coefficients coupled with good sensitizing properties for use in such materials at wavelengths in the visible spectrum region of about 400 nm.

摘要： Photosensitizing dyes are often used in conjunction with a photoacid generator in holographic recording media. Conventional photosensitizing dyes typically are limited by having an appreciable absorption of light when used in a sufficient concentration, such that the intensity of light decreases significantly with penetration into a recording medium. The present invention discloses a number of new 5-alkynyl substituted napthacene photosensitizing dyes that have low extinction coefficients coupled with good sensitizing properties, such that the problems associated with the photosensitizing dyes absorbing light are significantly reduced.

摘要： Disclosed is an optical disk, card or media which comprises: a) a plurality of data structures that are readable by the interrogating beam of light; and b) a composition on or in the optical disk, card or media disposed so that when the optical disk, card or media is used in the optical read-out system, the interrogating beam of light passes through the composition before or after contacting some or all of the data structures. The composition comprises a polymeric matrix with an organometallic complex dissolved therein or with metal, transition metal, metal oxide or transition metal oxide nanoparticles uniformly dispersed therein. The composition is substantially transparent to the interrogating beam and/or is substantially colorless. Alternatively, the composition comprises a solid polymeric matrix with an olefinic compound dissolved or uniformly dispersed therein wherein double bond in the olefinic compound undergoes oxidative cleavage promoted by a transition metal catalyst and a thiophenol or a catalytic amount of a thiyl radical and wherein the composition is substantially transparent to the interrogating beam and/or is substantially colorless.

摘要： An apparatus and method that produces recording media using at least two platens (16, 18). A first platen (16) is movable relative to a second platen(18), and each platen has respective first and second support surfaces onto which substrates (12, 14) are placed, the first and second substrates each having inner and outer longitudinal surfaces. A centering device (19) aligns the respective substrates relative to a one or more reference positions, a positioning system (32) provides a degree of parallelism between the outer longitudinal surfaces of each of the substrates (12, 14) and produces a desired gap between the inner longitudinal surfaces of the substrates(12, 14) , and a dispensing unit which emits a liquid medium within the gap between inner longitudinal surfaces of the substrates.
