| titleOfInvention | High contrast photographic emulsions containing a phenyl hydrazine derivative |
| abstract | HIGH CONTRAST PHOTOGRAPHIC EMULSIONS AND ELEMENTS AND PROCESSES FOR THEIR DEVELOPMENT Abstract of the Disclosure This invention relates to a photographic element comprising a support, and coated on the support at least one negative-working photographic emulsion comprising radiation-sensitive silver halide grains capable of form-ing a surface latent image and a binder, and in the support or in a remaining hydrophilic colloid layer coated on the support in an amount sufficient to increase contrast, a hydrazine compound of the formula wherein R1 is a phenyl nucleus having a Hammet sigma value-derived electron withdrawing characteristic of less than +0.30. |
