A composition includes a siloxane of the formula:(RMeSiO)(MeRSiO)(RSiO)(SiO)wherein a is at least 2, b is from 3 to 20, c is from 0 to 10, d is from 0 to 10, and each R is independently of the formula &#x2014;CR'&#x2014;CR&#x2032;&#x2014;Y&#x2014;Z or CR&#x2032;&#x2014;CR&#x2032;&#x2014;Z, wherein each R&#x2032; is independently a hydrogen atom or a Cto Chydrocarbyl free of aliphatic unsaturation so long as at least one R&#x2032; is a hydrogen atom, Y is a divalent organic group, and Z is a polycyclic group containing at least one aromatic ring. A method of making the siloxane includes charging (HMeSiO)(MeHSiO)(HSiO)(SiO), a platinum catalyst, and an alkene of the formula CR&#x2032;&#x2550;CR&#x2032;&#x2014;Y&#x2014;Z or CR&#x2032;&#x2550;CR&#x2032;&#x2014;Z into a reactor to form the siloxane. The siloxane is useful as a component in holographic storage media for photopolymer-based holographic data storage applications. The siloxane exhibits excellent compatibility when mixed with a polymerizable component before the polymerizable component is cured. Furthermore, the siloxane exhibits excellent diffusion from polymers of the polymerizable component after partial and complete curing. The siloxane also has a high refractive index while maintaining the excellent compatibility and diffusion properties when mixed with polymerizable component.

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.

A process for generation of acid uses a medium comprising a first acid-generating component capable of generating a first acid, and a secondary acid generator, this secondary acid generator being capable of thermal decomposition to form a secondary acid, the thermal decomposition of the secondary acid generator being catalyzed by the first acid. At least part of the medium is exposed to so as to cause formation of the first acid from the first acid-generating component; and the medium is then heated to cause, in the exposed part of the medium, acid-catalyzed thermal decomposition of the secondary acid generator and formation of the secondary acid. The secondary acid generator has a first site bearing a first leaving group and a second site bearing a second leaving group, the first leaving group being capable of protonation by the first acid, with expulsion of the first leaving group to form a cation which electrophilically adds to an unsaturated reagent bearing a proton at the site of addition and a proton-containing nucleophilic grouping at an adjacent site, following which said proton on the reagent is lost and the second leaving group is displaced by said nucleophilic grouping, the second leaving group, in combination with a proton, forming the secondary acid. Preferred variants of the process are of the types described in U.S. Pat. Nos. 5,286,612; 5,334,489; 5,395,736; 5,441,850 and 5,453,345.
