    • A method for producing light-sensitive material by using a curtain layer of coating solution. The method includes the steps of: discharging coating solution, including the light-sensitive material, from a coater die; forming a curtain layer of coating solution by causing the coating solution to fall from a die lip of the coater die in which the coating solution has at least 3 layers and a relational structure of dynamic surface tensions of the layers, satisfying the equation: .DELTA.K=.sigma.intermediate.sub.min -.sigma.outer.sub.max .gtoreq.0�mN/m! in which, .sigma.intermediated.sub.min �mN/m! represents the minimum value of dynamic surface tension of an intermediate layer among the layers, .sigma.outers.sub.max �mN/m! represents the maximum value of dynamic surface tension of an outer layer among the layers; and coating a continuous support with the coating solution.
    • 通过使用涂布液帘幕来生产感光材料的方法。 该方法包括以下步骤:从涂布机模具中排出包括感光材料的涂布溶液; 通过使涂布液从涂层溶液的至少3层的涂布机模具的模唇和层的动态表面张力的关系结构下降而形成涂层溶液的帘层,满足以下等式:DELTA K 西格玛中间分辨率= m [mN / m],其中,σ中间值min [mN / m]表示层间中间层的动态表面张力的最小值,σoutersmax [mN / m]表示 层间外层动态表面张力的最大值; 并用涂布溶液涂覆连续的载体。
