PROBLEM TO BE SOLVED: To provide a high-reflectance white coating layer that can be favorably used as a solder resist or the like for a printed circuit board on which light-emitting components such as LEDs are to be mounted, to provide a method of forming the high-reflectance white coating layer, and to provide the printed circuit board using the high-reflectance white coating layer.SOLUTION: A white coating layer is composed of a coating film formed by using a white curable composition containing titanium oxide. The white coating layer is formed by laminating two or more layers of the coating film. |
