珠光纸的构成和普通白板纸相同，即由底层纤维、填料和表面涂层三部分组成。与普通白板纸不同的是其表面涂层中有形成珠光效果的颗粒。该颗粒由二氧化钛（或是其它金属氧化物）和云母颗粒组成，云母颗粒被二氧化钛（或其它金属氧化物）包裹而形成，此结构呈薄片状。
The composition of pearlescent paper is the same as that of ordinary white board paper, which is composed of three parts: bottom fiber, filler and surface coating. Unlike ordinary white board paper, there are pearlescent particles in its surface coating. The particles are composed of titanium dioxide (or other metal oxides) and mica particles. Mica particles are wrapped by titanium dioxide (or other metal oxides) and form a thin sheet structure.
