Abstract A method of preparing a light sensitive silver halide phtographic material is disclosed. The photographic material comprises a polyester support having a hydrophobic polymer layer containing a vinylidene chloride copolymer and at least one hydrophilic polymer layer. The method comprises steps of coating a hydrophilic polymer layer onto the polyester support, drying the layer until a water content of the layer reaches 60 wt %, and contacting the layer with air having a relative humidity of 5 to 25% for a period 5 seconds to 10 minutes. The photographic material according to the method has such a physical characteristics as dimensional stability for long time storage or anti-cracking of the photographic layer at the preparation period. It is suitable for printing use.
