Abstract: Described are holographic storage mediums and method of making holographic storage mediums. The holographic storage mediums may have write components that bind to the matrix to form a pattern in the media. The holographic storage mediums may also be rewriteable.

Abstract: A novel photoimageable system for a two-chemistry system containing liquid photoreactive asymmetric acrylate compound containing sulfur, aromatic moieties, and optionally bromine, and an aluminum salt compound is disclosed. The photoimageable system has high dynamic range (M/#) and sensitivity and unexpectedly high temperature and high humidity resistance. The photoimageable system retains its dynamic range when exposed to 60° C. for 4 weeks while a composition without the aluminum salt compound lost 75% of its dynamic range under similar exposure conditions. In one embodiment, 2-10 weight % of a thio-butylacrylate dissolved in a two-component urethane matrix containing 0.002 to 1 weight % of the aluminum salt compound showed a dynamic range of greater than 5 for a 200 microns thick sample and retained more than 80% of the dynamic range after 4 weeks exposure at 60° C.

Abstract: A novel liquid photoreactive asymmetric acrylate compound containing sulfur, aromatic moieties, and optionally bromine, and having high dynamic range sensitivity is disclosed. The acrylate compound is a monomer for a photoimageable system. In one embodiment, when about 2–8% by weight of the acrylate compound is dissolved in a two-component urethane matrix system and incorporated in an optical article formed by reacting the two-component urethane matrix system, the optical article shows a sensitivity of about 4 or more and a shrinkage during the formation of the optical article of about 0.05% versus a sensitivity of 2.26 and a shrinkage of 0.13% when tribromophenyl acrylate, a commercial monomer, was used.

Abstract: Photothermally sensitive recording sheets for color imaging are disclosed comprising a transparent support sheet having a thermal slip layer disposed on one surface of the support and a heat sensitive image layer on the opposite surface of the support. A second opaque (paper) or transparent (plastic) sheet is laminated to the color-producing layer. The image layer comprises photohardenable microcapsules containing a photopolymerizable or photocrosslinkable compound, a photoinitiator and a dye precursor and a developer material external to the microcapsules. Image-wise exposure of the recording sheet to actinic radiation causes selective photohardening of microcapsules sensitive to that radiation. Heating the resultant exposed recording sheet to a temperature well above the developer melting point by for example a thermal head allows the developer to selectively permeate the non-photohardened capsules resulting in the development of an image, including full color images.

Abstract: A method for producing a differentially dyeable polyamide is disclosed. Polyamides produced according to the process of this invention will have distinct areas thereon that show varying degrees of receptivity to acid dyes and can thereby be differentially dyed using a single dyebath.

Abstract: A method for producing a differentially dyeable polyamide is disclosed. The method comprises selectively reacting a polyamide's free amines with an N-halogenating agent. Polyamides produced according to the process of this invention will have distinct areas thereon that show varying degrees of receptivity to acid dyes and can thereby be differentially dyed using a single dyebath.

Abstract: N-chlorolactams, -amides, and -carbamates are photolyzed in alcoholic solution to provide N-(alpha-alkoxyalkyl)-substituted derivatives. These derivatives are interacted with hydroxylated acrylate or methacrylate esters to yield monomers which may be polymerized in the presence of an appropriate initiator. Many of the monomers are water soluble and are useful to prepare polymeric films having unique properties.
