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. ## Claims ### Claim 1 A colouring structure, comprising: a substrate; a colouring layer disposed on at least a part of the substrate wherein the substrate and the colouring layer are made from different materials and have different water absorption properties; a plurality of colouring areas on the colouring layer; and at least one separating area on the colouring layer, wherein the colouring areas are at least partially defined by the separating area. ### Claim 2 (depends on 1) The colouring structure of claim 1, wherein the separating area has the same density as the colouring areas, and wherein a thickness of the separating area is 80% or less of a thickness of the colouring areas. ### Claim 3 (depends on 1) The colouring structure of claim 1, wherein the separating area has the same density as that of the colouring areas, and wherein a thickness of the separating area is 50% or less of a thickness of the colouring areas. ### Claim 4 (depends on 1) The colouring structure of claim 1, wherein the separating area has a width of at least 1 millimeter. ### Claim 5 (depends on 1) The colouring structure of claim 1, wherein the colouring layer is a blotting paper. ### Claim 6 (depends on 1) The colouring structure of claim 1, wherein a surface of the substrate is coated with a coating that increases a surface tension of the substrate. ### Claim 7 (depends on 1) The colouring structure of claim 1, wherein the colouring layer is fixed on a surface of the substrate using an adhesive. ### Claim 8 (depends on 1) The colouring structure of claim 1, wherein the colouring structure is a three-dimensional structure. ### Claim 9 (depends on 1) The colouring structure of claim 1, wherein the colouring structure is a planar structure. ### Claim 10 (depends on 1) The colouring structure of claim 1, wherein the colouring layer contains from about 80% to about 90% of wood pulp, from about 5% to about 8% of water, and a small amount of glue and additive. ### Claim 11 (depends on 1) The colouring structure of claim 1, wherein the separating area is cut into, but not all the way through, the colouring layer. ### Claim 12 A colouring structure, comprising: a substrate; a colouring layer disposed on at least a part of the substrate, wherein the substrate and the colouring layer are made from different materials and have different water absorption properties; a colouring area on the colouring layer; and a separating area on the colouring area, wherein the colouring area is at least partially defined by the separating area. ### Claim 13 (depends on 12) The colouring structure of claim 12, wherein the separating area has the same density as the colouring area, and wherein a thickness of the separating area is 80% or less of a thickness of the colouring area. ### Claim 14 (depends on 13) The colouring structure of claim 13, wherein the thickness of the separating area is 50% or less of the thickness of the colouring area. ### Claim 15 (depends on 14) The colouring structure of claim 14, wherein the separating area has a width of at least 1 millimeter. ### Claim 16 (depends on 15) The colouring structure of claim 15, wherein the colouring layer is a blotting paper. ### Claim 17 (depends on 16) The colouring structure of claim 16, wherein a surface of the substrate is coated with a coating that increases a surface tension of the substrate. ### Claim 18 (depends on 17) The colouring structure of claim 17, wherein the colouring layer is fixed on a surface of the substrate using an adhesive. ### Claim 19 (depends on 18) The colouring structure of claim 18, wherein the colouring layer contains from about 80% to about 90% of wood pulp, from about 5% to about 8% of water, and a small amount of glue and additive. ### Claim 20 (depends on 19) The colouring structure of claim 19, wherein the separating area is cut into, but not all the way through, the colouring layer.
