Anti-ultraviolet cellulose hollow capsule shell

The invention provides an anti-ultraviolet cellulose hollow capsule shell. The anti-ultraviolet cellulose hollow capsule shell is characterized in that a capsule wall is of a structure with three layers or more than three layers of matrix layers; each matrix layer contains hydroxypropyl methyl cellulose; the thickness of each matrix layer is gradually reduced from outside to inside along the thickness direction of the capsule wall. According to the cellulose hollow capsule shell provided by the invention, interfaces among the plurality of layers of matrix layers with different thicknesses havea reflection effect on ultraviolet rays, the speed of irradiating pigments in the cellulose hollow capsule shell by ultraviolet rays to be decomposed is reduced and the preservation time of the colored cellulose hollow capsule shell is prolonged. 种纤维素空心胶囊壳，其特征在于，胶囊壁具有3层或3层以上的基体层结构，所述的各基体层都含有羟丙甲基纤维素，且在胶囊壁的厚度方向上由外而内各基体层的厚度递减。本发明的纤维素空心胶囊壳通过多层不同厚度的基材层之间的界面对紫外线的反射效果，降低纤维素空心胶囊壳中颜料被紫外线照射而分解的速率，延长有色纤维素空心胶囊壳的保存时间。
