The same result as in Table 1 can be obtained by checking the adhesion of the photosensitive material dust.

Example 5 Backing was performed in the same manner as in Example 1 except that the coating amount of cobalt-γ-iron oxide of the magnetic recording layer constituting the backing layer of Example 1 was reduced to 57 mg / m ² to 30 mg / m ^2. A layered support was obtained. Using this support, the first to first photosensitive layers as the sample 101 of Example 1 of JP-A-7-225559 were formed on the undercoat layer opposite to the backing layer with the base interposed therebetween.
Nine layers were provided to produce a reversal color light-sensitive material, and the color development process described in Example 1 was performed.
When suspended at 5 ° C. and air-dried, the presence or absence of traces of water droplets after drying was visually observed. As a result, the ion complex comprising the cationic surfactant and the anionic surfactant containing the slipping agent of the present invention was obtained. It was confirmed that the support having the backing layer coated with the coating solution composition of the organic solvent contained almost no trace of water droplets. In addition, it was also confirmed that an excellent coating surface was provided in terms of coatability, and good results were obtained with almost no adhesion of photosensitive material dust.

Example 6 The same procedure as in Example 1 was carried out except that 3 g of the carnauba wax of Example 1 was replaced with a mixture of 2.5 g of Exemplified Compound (11) and 0.5 g of Exemplified Compound (23). Japanese Patent Application No. 8-188,083 discloses a coating liquid composition for the outermost layer of the backing layer (corresponding to 101 to 122), which is coated on the undercoat layer opposite to the backing layer with the base interposed therebetween. 1. A color negative photosensitive material was prepared by providing the first to twelfth photosensitive layers of the sample 110, and the photosensitive material was attached in the same manner as in Example 1 using the color negative photosensitive material. 1
The color development described in Example 1 above was carried out, the drying was suspended, and the wettability when air-drying was performed was visually observed in the same manner as in Example 3. As a result, the same tendency as in Example 1 was confirmed. The same applies to a black-and-white negative photosensitive material provided by changing the coating of the photosensitive layer to the same first to fifth layers as the sample 101 described in Example 1 of Japanese Patent Application No. 7-325252.
