Title:
銀分散ポリペプチド
Document Type and Number:
Japanese Patent JP4066420
Kind Code:
B2
Abstract:
Silver halide emulsions for photographic uses contain a nucleation peptiser having at least one region A of up to 100 amino acids. Region A can either consist of (i) at least two silver-binding amino acids and up to 98 amino acids between the two silver-binding amino acids, or can consist of (ii) a stretch of from 9 to 100 amino acids having a polarity corresponding to an average transfer free energy DeltaF equal to or higher than +1.0 kcal/mol. The nucleation peptizer also has at least one region B (separated from region A) having at least 50 amino acids and having a polarity corresponding to an average transfer free energy equal to or lower than -1.0 kcal/mol and not containing methionine residues. The emulsion may also contain a growth peptiser having similar characteristics to the nucleation peptiser, but having a longer A region and a greater overall length.
