PROBLEM TO BE SOLVED: To provide an ink jet recording method and a material therefor wherein an image of high quality, which has a high density and has particularly a maximal transmission density of 3 or more and has less roughness, can be formed. SOLUTION: In the ink jet recording method, wherein a plurality of heads are provided and ink of different kinds is projected from each of the heads to form an image on a picture material, at least one kind of ink component reacts in the picture material so as to increase optical density. For example, an amplification action which is caused by organic silver salt and reducing agent, a reaction wherein a cobalt complex, in which ammonia or amine is coordinated, reacts with a reducing agent to generate ammonia so that the ammonia reacts with dialdehyde compounds to cause polymerizing color development, and an action wherein metal ion feed compounds are present in a picture material and a dye capable of chelating ink components causes a chelating reaction in a picture material to increase density are preferably employed. |
