Colouring Structure

Abstract

A colouring structure comprising: a substrate, and a colouring layer disposed on at least a part of the substrate; the substrate and the colouring layer are made from different materials and have different water absorption properties, the colouring structure comprises a plurality of colouring areas and at least one separating area, wherein the colouring area is at least partially defined by the separating area. The colouring structure allows the user to easily grasp the pattern engraved on the colouring structure, which can rapidly absorb the liquid such as ink added to the surface thereof and effectively slow the horizontal diffusion of the liquid added to the colouring layer. For liquids with high water content, the high water absorption of the colouring structure avoids or effectively reduces accidents caused by the use of high-water-content liquids, such as liquid leakage, and liquid spillage and dirtying clothes or body parts over large areas.
