Silver diffusion transfer receiving layer comprising HEC and gelatin |
摘要 |
A receiving element for use in a photographic silver diffusion transfer process which comprises a transparent support carrying a layer comprising gelatin, hydroxyethyl cellulose and noble metal silver-precipitating nuclei; wherein said nuclei are present in a level of from about 0.1-0.4 mgs/ft2, gelatin is present at a level of from about 0.05 to 1.5 mgs/ft2 and hydroxyethyl cellulose is present at a level of about 0.1 to 7 mgs/ft2. Preferably, the noble metal is palladium. The receiving element is particularly useful in an additive color diffusion transfer process.
