摘要： The present invention discloses a new class of triarylsulfonium salt photoacid generators (PAGs), which are thermally stable and can be activated by long wavelength UV or visible light. The sulfonium PAGs of the present invention are additionally soluble in monomers that can be polymerized by cationic polymerization chemistry, and mixtures of said sulfonium PAGs and monomers can be stored for long periods of time without undergoing polymerization. Furthermore, typical holographic recording media comprising one of these sulfonium PAGs, polymerizable monomer(s), a sensitizing dye, and a binder can be stored for long periods of time without exhibiting significant loss of recording sensitivity. Preferred sulfonium PAGs of the present invention are sulfonium PAGs substituted with one or more fluoro or fluoroalkyl groups.

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.
