    • A process for the dispersion of a dyestuff represented by the following formula (I), which comprises the acceleration of molecular orientation in advance and/or during the dispersion and/or after the dispersion:



              D - (X) y    (I)



      wherein the terms are as defined herein. In a preferred embodiment, formula (I) is represented by the following formula (II) and the acceleration of molecular orientation is carried out by heating:



              A₁ =(L₁ - L₂) m = L₃ -(L₄ = L₅) n - A₂   (II)



      wherein the terms are as defined herein and the heating may be effected in the presence of an organic compound containing carboxylic group. A silver halide photographic material, which comprises a dyestuff dispersed therein in accordance with the dispersion process as defined above, the dyestuff may be represented by formula (II), the ratio of the absorbance at 680 nm to that at 530 nm in the absorption spectrum of the dyestuff is 0.50 or less, and the ratio of the primary diffraction intensity when the diffraction angle 2 ϑ of X-ray diffraction of the dyestuff is about 26 to 27 degrees to the secondary diffraction intensity when the diffraction angle 2 ϑ is about 14 degrees may be 1.30 or less.
