    摘要: Solid particle dispersions of certain ascorbic acid esters are prepared in the presence of at least 0.5 and less than 50 weight % of a particle growth modifier based on the weight of the ascorbic acid ester. The particle growth modifier is an alkyl carboxylic acid having from 8 to 22 carbon atoms, an alkyl ester of glycerol wherein the alkyl moiety has from 8 to 22 carbon atoms, or a stereoisomer of the ascorbic acid ester. The resulting aqueous solid particle dispersion can be used in various thermally developable materials including thermographic and photothermographic materials.

    摘要: High-speed black-and-white photothermographic materials can be imaged in any suitable fashion using ultraviolet, visible, infrared, or X-radiation. They can have one or more thermally developable imaging layers on either or both sides of the support and can be imaged with or without a phosphor intensifying screen in an imaging assembly. The photothermographic emulsions and materials have a net Dmin less than 0.25, and require less than 1 erg/cm2 to achieve a density of 1.00 above net Dmin.

    摘要: A polymerizable composition of polyurethane precursors is rapidly cured using energy-activated catalysts to provide polyurethanes. The polymerizable composition is comprised of polyisocyanates with polyols, fillers, coating aids, adjuvants, and a latent catalyst. Latent catalysts are ionic salts of organometallic complex cations. The cured polyurethanes are useful as abrasion resistant coatings, protective finishes such as furniture finishes and floor tiles, binders for magnetic media, adhesives, and have various applications in industries which use photoresist technologies such as graphic arts and electronics, and in the paint and ink industries.
