摘要： PROBLEM TO BE SOLVED: To obtain a photographic element which ensures suppressed crystal formation while retaining satisfactory reactivity and the absorption of unnecessary green light by allowing a 2nd high boiling point solvent to exist in an enough amount to suppress crystal formation in a dispersion of a coupler as compared with a dispersion of the coupler in a dispersion in which the 2nd solvent has been substituted by a 1st high boiling point solvent equal to the 2nd solvent in amount. SOLUTION: The photographic element includes a silver halide emulsion layer having a phenolic cyan dye forming NB coupler, a 1st high boiling point solvent having the formula G-C-00-R1 and one or more 2nd high boiling point solvents selected from phosphates, phosphonates, etc. The 2nd solvents are allowed to exist in an enough amount to suppress crystal formation in a dispersion of the coupler as compared with a dispersion of the coupler in a dispersion in which the 2nd solvents have been substituted by the 1st solvent equal to the 2nd solvents in amount. In the formula, R1 is alkyl or aryl and G is alkyl including cycloalkyl and aralkyl and containing a bonding group.

摘要： PROBLEM TO BE SOLVED: To increase the wet mechanical strength of a gelatin coating without increasing the amount of a chemical cross-linking agent or modifying the functional groups of the gelatin. SOLUTION: The image forming element comprises one or more hydrophilic colloidal layers containing gelatin chemically crosslinked with a gelatin hardening agent as a film forming binder, wherein at least 20% of the gelatin in at least one of the one or more hydrophilic colloidal layers comprises gelatin prepared from hydrolysis of ossein using sodium hydroxide or potassium hydroxide and this gelatin has been chemically crosslinked with a gelatin hardening agent on a level of 70-120 effective micromol hardening agent per 1 g gelatin.

摘要： PROBLEM TO BE SOLVED: To obtain a photographic element containing a dispersion of cyan dye forming coupler having improved light stability and dark stability, improved color reproducibility and high reactivity with an oxidized color developing agent by incorporating a phenolic cyan dye forming NB coupler, a specified phenolic cyan dye forming coupler and a specified stabilizer. SOLUTION: The photographic element includes at least one photosensitive silver halide emulsion layer having a phenolic cyan dye forming NB coupler, a phenolic cyan dye forming coupler of formula I and a stabilizer of formula II. In the formula I, R3 is an optionally substituted alkyl or aryl or the like, R4 is an optionally substituted alky, R5 is H, a halogen, optionally substituted alkyl or aryl or the like and Z is H or a group which can be split by the reaction of the coupler with an oxidized color developing agent.

摘要： An imaging element is described comprising one or more hydrophilic colloid layers which include gelatin as a film forming binder which has been chemically crosslinked with a gelatin hardener, wherein at least 20% of the gelatin of at least one of the one or more hydrophilic colloid layers comprises a gelatin prepared from hydrolysis of ossein using sodium or potassium hydroxide, and the gelatin is chemical crosslinked with a gelatin hardener at a level from 70 to 120 effective mu mole hardener per gram of gelatin. Improvements are obtained in the wet mechanical strength of an imaging element comprising gelatin as a binder, without needing to increase the amount of chemical crosslinker with respect to the gelatin. The invention further enables the use of relatively low molecular weight gelatins without compromising the wet mechanical strength of imaging elements and without needing to increase the amount of crosslinker relative to the amount of gelatin. The invention also enables the selective improvement in the wet mechanical properties of layers with a high ratio of non-binder materials to binder without substantially increasing the amount of chemical crosslinker.
