Hologram silver halide photographic material, hologram and method for producing the same

A method for producing a hologram comprising the steps of:

• exposing a silver halide photographic material having at least one silver halide emulsion layer formed on a support to a light source to form an image;
• developing the photographic material with a developing agent containing a mixture of ascorbic acid, sodium carbonate and phenidone;
• and
• bleaching the photographic material with a bleach solution containing a mixture of parabenzoquinone, citric acid and potassium bromide, the photographic material containing gelatin and silver halide particles having an average particle diameter of 0.03 μm to 0.06 μm;
• the silver halide emulsion layer having a film thickness of 4 μm to 9 μm and a silver/gelatin ratio of 0.3 to 0.6, the silver halide emulsion layer containing at least one kind of compounds represented by the following general formula,
• wherein Y1 represents a —N(R)— group, an oxygen atom, a sulfur atom, or a selenium atom;
• R represents an aliphatic group having 10 or fewer carbon atoms;
• R1 represents an aliphatic group, aryl group or heterocyclic group which contains at least one water-soluble group as a substituted group;
• V1 and V2 respectively represent a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, or a substituted or non-substituted group forming a condensed ring with an azole ring by the bonding of V1 and V2;
• n represents 1 or 2 and m represents 0 or 1;
• L1, L2, L3 and L4 respectively represent a methine group;
• at least one of L1 and L2 has a substituted group having 3 or more carbon atoms and having an SP less than 539 when n is 1 or 2 and m is 0;
• and at least one of L1, L2, L3 and L4 has a substituted group having 3 or more carbon atoms and SP is less than 539 when n is 1 or 2 and m is 1;
• herein, SP is a value represented by SP=3.563L−2.661B+535.4;
• L represents a Sterimol parameter (Å);
• and B represents a value (Å) of the smaller one of the sum B1+B4 and sum B2+B3 of the Sterimol parameter;
• Q1 and Q2 respectively represent a nonmetallic atom group required for forming an acid ring;
• M1 represents an ion required for cancelling all the electric charges of a molecule, and n1 represents the number required for neutralizing the electric charges of the molecule;
• n1 is 3 or more.
