Developer dispersions for thermally developable materials |
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.
