摘要:
A photographic material having a light-sensitive silver halide emulsion layer coated on a support and containing a compound, useful as a development inhibitor of the formula: ##STR1## wherein X, Y and Z are as herein defined, is described.
摘要:
A light-sensitive silver halide photographic material comprising a new development inhibitor releasing type compound and a process for developing thereof.
摘要:
A light-sensitive silver halide photographic material containing a new development inhibitor releasing compound. The said compound has no hydrogen atom at the carbon atom which is adjacent to the carbonyl group and capable of coupling to an oxidation product of a color developing agent on the development.
摘要:
A process for forming a cyan dye image by using a novel photographic 2-equivalent cyan coupler which is characterized by having a splitt-off group of the below-indicated general formula at the active position of the cyan coupler so that the oxy portion is present on the side of the active position: ##STR1## wherein R.sub.1 and R.sub.2 stand for a hydrogen atom or an organic group, provided at least one of R.sub.1 and R.sub.2 should be an organic group, is disclosed.
摘要:
Color developers represented by the following general formula are useful as color developing agents: ##STR1## R.sub.1, R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are defined herein.
摘要:
A novel two-equivalent naphthol or phenol type cyan coupler is disclosed wherein the active position thereof has a split-off group which contains a bonding group of the formula ##STR1## wherein R is hydrogen atom or a divalent organic group. The present coupler is incorporated into a photographic material containing a photosensitive emulsion layer.
摘要:
A process for forming a photographic magenta dye image is disclosed which requires contacting exposed silver halide with a color developing agent in the presence of a particular class of 2-equivalent magenta couplers.
摘要:
Cyan couplers of the 2-equivalent type having the formula ##STR1## wherein C.sub.p, R.sub.1 -R.sub.6, Z, n, p and q are herein defined are described. These couplers are useful in photography, and photographic materials and developers incorporating these couplers are also described.
摘要:
The present invention discloses a multi-layer photosensitive material for color photography in which a compound capable of reacting with an oxidation product of a developing agent to release a substance promoting bleaching of developed silver at the bleaching or blixing step after the development treatment is incorporated into at least one layer constituting said photosensitive material.
摘要:
The present invention relates to a process for forming photographic images using a 2-equivalent magenta coupler position a radical of the following general formula:--O--SO.sub.2 --Rwhere R is an aliphatic hydrocarbon, aromatic hydrocarbon or heterocyclic residue.
