摘要： 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 ΔF 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.

摘要： The invention provides oil-in-water emulsions comprising recombinant collagen-like polymer in an amount sufficient to act as stabiliser of the emulsion. The polymer is especially a polypeptide which is free of helix structure, has an isoelectric point at least 0.5 pH units removed from the pH of the oil-in-water emulsion. Furthermore, amphiphilic recombinant collagen-like polymers are provided for use in oil-in-water emulsions. The amphiphilic polymers are polar at one end as a result of a relative abundance of polar amino acids, and apolar at the other end as a result of a relative abundance of apolar amino acids.
