其表面具有凹陷部分的固体的制造方法和制造电子照相感光构件的方法

Method of producing solid body having depressed portions on its surface and method of producing electrophotographic photosensitive member
Abstract:
A method for producing a solid body having depressed portions on its surface is provided. The method includes: using a solution which includes a solvent A, a solvent B, a solvent C, and a polymer compound, where the solvent B is a hydrophobic solvent, the solvent A is a hydrophilic solvent having a boiling point not lower than the boiling point of the solvent B, and the solvent C is a non-hydrophobic solvent having a boiling point lower than the boiling point of the solvent B, and the contents of the solvent A, solvent B, and solvent C satisfy specific conditions; and solidifying the solution while forming depressed portions on the surface of the solution by condensation during the process of evaporating the solvents included in the solution.
Abstract(Chinese):

提供了一种在其表面上具有凹陷部分的固体的制造方法。 该方法包括：使用包含溶剂A，溶剂B，溶剂C和高分子化合物的溶液，其中溶剂B是疏水性溶剂，溶剂A是沸点不低于 溶剂B的沸点，溶剂C是沸点低于溶剂B的沸点的非疏水性溶剂，溶剂A，溶剂B和溶剂C的含量满足特定条件; 并在溶液中包含的溶剂的蒸发过程中通过冷凝在溶液表面上形成凹陷部分而固化。
