た脱泡方法が記載されている。BACKGROUND OF THE INVENTION Generally, it is sometimes necessary to remove bubbles from a liquid. For example, when the coating liquid is applied to the support in a state where bubbles are mixed, the bubble portion becomes a coating defect and a uniform film cannot be formed, which is one of the major causes of the decrease in the yield. Therefore, it is necessary to perform defoaming treatment. For example, Japanese Patent Application Laid-Open Nos. 11-5001 and 11-90110 disclose coating solutions for silver salt photosensitive materials.
No. 4,143,747 and the like describe a defoaming method using ultrasonic waves.

Further improvement of the defoaming effect is required. Particularly in the coating of silver salt light-sensitive materials, in recent years, the viscosity has increased as the silver halide concentration has increased, and the liquid delivery flow rate has also increased with the increase in coating speed. Since a sufficient defoaming effect cannot be obtained, further improvement of the defoaming effect is required. The present invention has been devised to solve the above situation, and an object thereof is to further enhance the defoaming effect.
