摘要： PROBLEM TO BE SOLVED: To reduce cracks, and improve the water-resistance, the gloss property and the productivity by mixing a cationic polymer-containing liquid and an inorganic particle dispersion liquid which disperses to the state of a primary particle, then, adding a water-soluble polymer to form an application liquid, and applying the application liquid on a supporting body. SOLUTION: A cationic polymer is preferably a single polymer of a monomer having a quarternary ammonium salt group, or a copolymer with other one, or two or more monomers which can be copolymerized. As an inorganic particle, silica which has a low index of refraction and is excellent in transparency is preferably used. In such a cationic polymer solution, an inorganic particle dispersion liquid which disperses to a primary particle, and of which the average particle diameter is approx. 4-20 nm, is gradually added while sufficiently stirring, and mixed, and then, gelatin (preferably an acid treated gelatin) as a water-soluble polymer, polyvinyl pyrrolidone the average molecular weight is preferably approx. 200,000 or higher) or the like are added, and an application liquid is obtained, and the application liquid is applied on a supporting body without a mechanical dispersion.

摘要： PROBLEM TO BE SOLVED: To provide an image forming method with which images of a high density and excellent discrimination of low Dmin may be rapidly obtd. and further image preservation is excellent in the method for forming black and white images. SOLUTION: This image forming method forms the silver images by superposing the film surfaces of a silver halide photosensitive material including a photosensitive silver halide, a basic metal compd. hardly soluble in water, a hydrophilic binder and a reducing agent and a sheet contg. a compd. capable of making complex formation reaction with the metal ions constituting the basic metal compd. and physical development nuclei on each other after imagewise exposure or simultaneously with the imagewise exposure, then heating both in the presence of water and a silver halide solvent. In such a case, the basic metal compd. hardly soluble in the water and the compd. expressed by formula (R1 )n-Ar-Sh are incorporated into at least one layer constituting the silver halide photosensitive material. In the formula, R1 denotes an aliphat. group, arom. group, heterocyclic group, carboxyl group, acyl group and sulfonyl group and Ar denotes a carbon arom. ring or heterocyclic arom. ring.
