Powder and laminates using the same

Abstract

To provide powder capable of easily forming a tough metal oxide surface for a metal oxide coating on an organic material substrate.SOLUTION: Powder containing a metal oxide satisfies the following conditions (1) and (2). (1) The powder has a peak top of the particle size in the range of 0.1 μm or greater and less than 5 μm and 5 μm or greater and less than 50 μm in a frequency distribution curve obtained in volume-based particle size distribution measurement using a laser diffraction scattering system. (2) The powder has a difference between a tap bulk density and an initial bulk density satisfying the following relation. 0.88 g / cm3≤(tap bulk density-initial bulk density)≤0.94 g / cm3.SELECTED DRAWING: Figure 1
