Description

Technical Field

[0001] The invention relates to the technical field of notebooks, and in particular to a paper and a notebook for assisting memory. Background Art

[0002] Paper is a kind of stationery commonly used to record information, which is common in daily learning and office activities. People often bind a certain amount of paper into a book and use it as a medium for writing. This process of writing on paper to record information is usually called taking notes. In daily life, when people study or read, they often write at the same time, recording what they have learned and read while understanding it. When the first study or reading is finished, the corresponding notes are also compiled.

[0003] Taking notes is widely considered an effective learning strategy because it helps learners organize their thoughts, highlight key points, and provide review materials in the subsequent learning process. By taking notes, learners can deepen their understanding of knowledge, improve memory efficiency, and quickly review key information when needed. The famous Ebbinghaus memory forgetting curve also proves the importance of recording and reviewing notes.

[0004] During the review and memorization process, when the human eye reads the text, the recorded content will be completely presented in front of the learner. Because the content has been memorized before, the learner will have an illusion that the knowledge points he sees have also been remembered. However, in fact, these knowledge points may have only been noticed briefly and have not been fully memorized. At the same time, when reading text, the human eye does not scan each word one by one, but performs regional scanning. This scanning method allows the human eye to capture information from multiple characters at the same time. Due to the limitations of ordinary notebook recording methods, the recorded note information is relatively concentrated. When reviewing the current knowledge point, other knowledge points scanned by the peripheral vision will interfere with the memory of the current review knowledge point, and learners will also think that the points scanned by their peripheral vision are also remembered, and will then ignore the knowledge points scanned by the peripheral vision. Summary of the invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a paper and a book for assisting memory. When using the paper, the paper can assist learners in memory, optimize learning experience and review efficiency.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] The present invention provides a memory-aiding paper, comprising an additional layer, wherein the additional layer is embedded in the surface of the paper body at intervals, and during writing or printing, part of the content falls on the additional layer.

[0008] Furthermore, the additional layer is a hydrophobic or oleophobic layer, a thermosensitive layer, a force-sensitive layer, an acid-base indicating layer or a color fixing layer.

[0009] Furthermore, the hydrophobic and oleophobic layer is a high-density polymer coating or a membrane structure.

[0010] Furthermore, the additional layer is an interference layer for reducing the resolution, and the interference layer is formed by interference blocks being embedded in the surface of the paper body at intervals.

[0011] Furthermore, the interference block is formed by applying or printing a certain pigment on the surface of the paper body, or by evenly mixing an oxidant, a catalyst, a pigment and a solvent and then applying or printing on the surface of the paper body, and the interference block can oxidatively decompose the information written or printed in this area.

[0012] Furthermore, the paper body includes a bottom layer and a writing layer stacked on the top of the bottom layer, the additional layer is arranged on the upper surface of the writing layer, a first transfer area is provided on the back of the writing layer, and a first developing area is provided on the upper surface of the bottom layer, the first developing area corresponds to the first transfer area one by one, and the first transfer area is formed by the embossing coating adhering to the lower surface of the writing layer.

[0013] Furthermore, the paper body includes a bottom layer and a writing layer arranged on the upper end of the bottom layer, a transfer layer is arranged between the bottom layer and the writing layer, the additional layer is arranged on the upper surface of the writing layer, a first transfer area is arranged on the back of the writing layer, a second developing area corresponding to the first transfer area is arranged on the upper surface of the transfer layer, a second transfer area is arranged on the back of the transfer layer, and a first developing area corresponding to the second transfer area is arranged on the upper surface of the bottom layer, the first transfer area and the second transfer area are staggered and connected, and after the first transfer area and the second transfer area are connected, they overlap with the area where the additional layer is located or exceed the area where the additional layer is located.

[0014] Furthermore, the first transfer area is formed by the embossing coating layer adhering to the lower surface of the writing layer, and the second transfer area is formed by the embossing coating layer adhering to the lower surface of the transfer layer.

[0015] Furthermore, the embossed coating is a microcapsule or a carbon black coating containing a limin pigment oil.

[0016] Furthermore, the embossing coating is an acid-base layer, and the surfaces of the first developing area and the second developing area are both attached with an acid-base indicating layer.

[0017] The present invention also provides a booklet for assisting memory, which is formed by binding the above-mentioned paper sheets.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) The paper body of the present invention is provided with additional layers at intervals. When a user writes or prints notes on the paper body, a portion of the content falls on the additional layers. Since the additional layers have been specially processed, only a portion of the writing on the paper can be retained, either on the additional layers or in an area outside the additional layers. After the user has completed writing and printing the notes, when the paper is used for memorization or review, since a portion of the information is not preserved and another portion of the information is retained for a long time, the user needs to supplement and complete the note information based on the existing information. When supplementing the current content, the memory can be strengthened. At the same time, since the information scanned by the peripheral vision is also incomplete information, it will not interfere with the memory of the target information.

[0020] (2) The additional layer on the paper body of the present invention is formed by an interference block, wherein the color of the surface of the interference block is consistent with or similar to the color of the pen and ink. When the user is writing, the content falling in the additional layer area will have a low resolution or lose resolution, thereby interfering with the human eye's extraction of written or printed information in the additional layer area, achieving the hiding of part of the written and printed information, and assisting the user's reading and memory. During the review process, even if the eye scans the information of other knowledge points, the user cannot directly distinguish it because there is also a large amount of interference information, forcing the user to give priority to processing the current information, and has no time to take into account other information scanned by the peripheral light, thereby improving the review efficiency of the current knowledge point.

[0021] (3) In the present invention, the writing layer and the bottom layer are used in combination, or the writing layer, the transfer layer and the bottom layer are used in combination. When writing or printing notes, part of the information of the notes is recorded on the writing layer, and the information not recorded on the writing layer will be printed on the bottom layer and the transfer layer, so that the content on the writing layer and the printed content complement each other and can constitute a complete note content. That is to say, through the combination of paper, the user's writing or printing once forms multiple incomplete but complementary notes. When the user is reviewing knowledge points, he can use one of the incomplete notes as a reminder to review the memory, complete the knowledge points in the brain, and thus strengthen the memory. For the knowledge points that cannot be fully mastered, he can directly read the other part of the complementary notes to strengthen the memory. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The embodiments of the present invention will be described in detail below with reference to examples, but those skilled in the art will understand that the following examples are only used to illustrate the present invention and should not be construed as limiting the scope of the present invention.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] In the following description, specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in a variety of other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Example 1

[0038] refer to Figures 1 to 3This embodiment proposes a memory-aiding paper, including an additional layer 2, wherein the additional layer 2 is embedded in the upper surface of the paper body 1 at intervals, and the upper surface of the additional layer 2 is preferably flush with the upper surface of the paper body 1. During the writing process, part of the content falls on the additional layer 2. The shape of the additional layer 2 can be determined according to design requirements. In this embodiment, it is preferably rectangular, wherein the paper body 1 can be paper made of plant fibers or paper made of non-plant fiber materials. The non-plant fibers include synthetic fibers, inorganic fibers, etc. The additional layer 2 is specially treated so that when the user writes or prints a text image, only one area of ​​the additional layer 2 and the area outside the additional layer can preserve the handwriting.

[0039] Exemplarily, the additional layer 2 may be a hydrophobic and oleophobic polymer coating or film structure, such as a PET (polyethylene terephthalate) film, HDPE (high-density polyethylene) film, PVC (polyvinyl chloride) film, LDPE (low-density polyethylene) film, PP (polypropylene) film, PS (polystyrene) film or other additional layer 2 made of materials that meet the requirements. During the writing or printing process, since the ink or ink cannot be adsorbed on the hydrophobic and oleophobic layer, the handwriting cannot be retained on the additional layer 2, and the ink or ink left on the surface of the additional layer 2 is wiped clean by the user using absorbent paper and a facial tissue. That is, the surface of the additional layer 2 only shows the pressure marks of writing, and as time goes by, the pressure marks of writing gradually disappear. The area outside the additional layer 2 on the paper body 1 can permanently retain the traces of user writing. When the user reads the notes later, he can only supplement and improve the auxiliary memory through the information outside the additional layer 2. At the same time, the additional layer 2 is waterproof and oil-proof. Each time the user writes, only the writing traces are left instead of real handwriting. After the user uses a pen to complete the missing content on the additional layer 2, he can use an erasing tool such as a paper towel or a towel to easily erase it, thereby realizing the repeated writing and utilization of notes to assist memory.

[0040] Exemplarily, the additional layer 2 can also be formed by fiber modification technology, that is, the structure and arrangement of paper fibers are changed by chemical or physical methods to make the paper itself have waterproof and oil-proof properties. This method usually involves modification of the paper fibers to enhance their waterproof and oil-releasing properties, so that the ink cannot be adsorbed onto the paper, and the writing or printing effect cannot be achieved. In the embodiment, multiple pieces of base paper can be pasted on the paper body 1, and then the pressure is increased by a machine to compress the positions of the multiple pieces of base paper to the same thickness as the paper body 1, that is, the density of the paper unit and the paper hardness of the additional layer 2 are changed by pressure, so that the ink cannot penetrate into the interior of the paper through the instantaneous writing action, thereby achieving a waterproof and oil-proof effect and making it impossible to save information.

[0041] Exemplarily, the additional layer 2 is a thermosensitive layer, that is, a coating or film structure formed by a thermosensitive material. The thermosensitive layer is mainly composed of thermosensitive pigments (such as colorless dyes, phenols or other acidic substances), polymers and other additives. These components can react chemically under heat conditions to release color. When the user uses a thermal pen or a thermal printer to write or print on paper, the heat generated by the pen tip reacts with the additional layer, so that the handwriting appears on the additional layer, while the area outside the additional layer on the surface of the paper body cannot display the written notes. Similarly, the additional layer 2 can also be a force-sensitive layer, which is filled with force-sensitive pigment oil. During the writing process, the pigment oil will leak out wherever the pen tip reaches, thereby displaying the handwriting on the additional layer 2, while the area outside the additional layer cannot display the handwriting.

[0042] Exemplarily, the additional layer 2 is an acid-base indicator layer, and the surface of the area outside the additional layer 2 on the paper body is treated with hydrophobicity and oleophobicity. The user uses weakly acidic or weakly alkaline pen and ink to write, and the text information is displayed on the additional layer using the principle of chemical color development reaction. Since the area outside the additional layer on the paper body 1 is treated with hydrophobicity and oleophobicity, the handwriting cannot be displayed. Conversely, calcium carbonate or calcium hydrogen phosphate can be used to adjust the pH value of the paper to form an additional layer 2. When the user uses a pen or tool containing an indicator to write, the pH regulating substance and the indicator in the additional layer 2 react to display the user's handwriting information, while the area outside the additional layer 2 is treated with hydrophobicity and oleophobicity, and the user's handwriting information cannot be displayed. In this example, the indicator in the pen can dissolve bromophenol blue and neutral red in a certain proportion in an appropriate solvent (such as ethanol, glycerol, etc.). Bromophenol blue and neutral red are two commonly used acid-base indicators, and they present different colors in different pH ranges. Bromophenol blue is yellow under acidic conditions, green under neutral conditions, and blue under alkaline conditions; while neutral red is red under acidic conditions, orange-yellow under neutral conditions, and yellow under alkaline conditions. By mixing these two indicators in a certain proportion, different font information writing effects can be achieved on the additional layer 2. At the same time, the area outside the additional layer 2 on the surface of the paper body cannot undergo chemical reactions due to the waterproof and oil-proof treatment, and cannot display and retain the user's handwriting information, or the color produced by the chemical reaction between the pH regulating substance and the indicator ink in the area outside the additional layer 2 is consistent with the background color, then the information in the area outside the additional layer 2 is reduced and loses resolution, and the user can only use the information on the additional layer to assist memory and review.

[0043] Exemplarily, the additional layer 2 is a color fixing layer. When the user uses volatile ink to write, the handwriting in the area outside the additional layer 2 on the paper body will evaporate and disappear automatically in a short period of time and cannot be preserved. The handwriting on the additional layer will form stable chemical bonds or compounds with the additional layer through chemical reactions, thereby preventing the decomposition or fading of the pigment and achieving permanent preservation of the handwriting.

[0044] The components of volatile ink include: volatile solvents, decomposable pigments, additives and binders. The volatile solvent can be an organic solvent with low boiling point and high volatility, such as ethanol, acetone or ethyl acetate. These solvents can dissolve the pigment and form a uniform ink. Such ink is easy to evaporate at room temperature, thereby accelerating the disappearance of the handwriting; decomposable pigments can be some special organic pigments or dyes, which are easy to decompose or fade under conditions of light, temperature or humidity. For example, some azo or phthalocyanine pigments will gradually decompose under certain conditions, causing the color to disappear; additives can be selected from wetting agents, co-solvents, stabilizers, thickeners, etc.; adding a small amount of additives can improve the performance or usage characteristics of the ink, such as fluidity, drying speed, etc. At the same time, some stabilizers or antioxidants can also be added to extend the shelf life of the ink. The selection of these additives needs to take into account their effects on the volatility of the ink and the decomposition rate of the pigment; the binder can be made of some synthetic resins or cellulose derivatives. These binders need to have a certain fluidity and film-forming properties in order to form a uniform ink film on the surface of the paper, so that the ink forms a uniform thin layer after printing or writing, and protects the pigment from falling off easily.

[0045] The fixing layer is formed by a fixing agent, which is evenly applied to the surface of the paper body by a spray gun, brush or roller, and allowed to dry naturally or heat-dry on the surface of the paper body to remove the solvent and form a dense fixing agent. The components of the fixing agent include reactive compounds, cross-linking agents, solvents, and additives. Reactive compounds can be selected from compounds with functional groups, such as organic compounds containing hydroxyl, amino, carboxyl, etc. These functional groups can react with pigments or dyes in inks to form stable compounds by condensation, esterification, amidation, etc.; cross-linking agents can be selected from multifunctional cross-linking agents, such as epoxy resins, polyurethanes, etc. These cross-linking agents can form a dense cross-linked network on the surface of paper, firmly fix the ink on the paper, and enhance the fixing effect; the solvent needs to be a solvent that is non-damaging to paper and volatile, such as ethanol, acetone, etc. These solvents can evaporate quickly after coating, leaving reactive compounds and cross-linking agents on the paper surface; additives can be selected as leveling agents, defoaming agents, thickeners, etc., and appropriate amounts of additives can be added to improve the coating performance, drying speed and film-forming properties of the fixing agent.

[0046] In this embodiment, the additional layer may also be an oxidation layer, and the ink falling on the additional layer will be oxidized and decomposed, so that the handwriting on the layer cannot be displayed, and only the handwriting outside the additional layer area can be retained.

[0047] Example 2

[0048] refer to Figure 4In this embodiment, additional layers are arranged at intervals on both the front and back sides of the paper body 1, so that both the front and back sides of the paper body 1 can be used, which can save materials and reduce costs.

[0049] Example 3

[0050] The present embodiment proposes a paper for assisting memory, comprising an additional layer, wherein the additional layer is an interference layer for reducing resolution, wherein the interference layer is formed by interference blocks intermittently embedded in the surface of the paper body, wherein the color of the upper surface of the interference block is the same as or similar to the color of the ink of the writing pen, and the text or image written or printed by the user falls on the additional layer 2 and is fused with the information of the additional layer. The information fusion utilizes the principle that the color of the ink of the writing or printing information is close or similar to the background color of the additional layer, thereby interfering with the extraction of the writing or printing information by the human eye in the area of ​​the additional layer 2, thereby reducing or losing the resolution of the text or image information on the additional layer 2, thereby achieving the hiding of part of the writing or printing information, and assisting the user's reading and memory. The color of the interference block may be monochrome or multiple colors, and the shape of the interference block may be determined according to design requirements, and may be color dots, color lines, color blocks of different shapes, etc.

[0051] Optionally, the additional layer 2 can also be an interference reagent coating made by evenly mixing color pigments and other raw materials such as oxidants, catalysts, solvents, etc., and use a spray gun or a brush to evenly apply the reagent on the surface of the paper body 1 to form an interference layer. In the early stage, the principle is the same as above. When the text or image written or printed by the user falls on the additional layer 2, it is merged with the additional layer information, so that the text or image information on the additional layer 2 is first reduced or loses resolution due to color. Subsequently, as time goes by, the text or image information of the additional layer 2 is gradually decomposed and oxidized by the additional layer 2, and the information in the additional layer 2 area disappears permanently, thereby realizing the hiding of part of the written or printed information, assisting the user's reading and memory.

[0052] Taking the commonly used black in writing or printing as an example, the CMYK color model is a color system that applies the subtractive principle. It plays an important role in the field of color printing and printing. Its name comes from four basic colors: cyan, magenta, yellow and black (Key / black). Black is represented by K to avoid confusion with blue.

[0053] In the CMYK color model, the values ​​of black are: C (cyan), M (magenta), and Y (yellow). The values ​​can vary, but usually these values ​​are relatively small, while the value of K (black) is 100%. However, in actual printing, in order to obtain a fuller and thicker black effect, the values ​​of C, M, and Y can also be appropriately increased, but the total value (C+M+Y+K) should generally not exceed a certain threshold (such as 250) to avoid problems such as the paper not being able to hold the ink or the printing having ghosting. For large-area black printing, it is recommended to use black after the CMYK four-color superposition (such as C:75, Y:67, M:68, K:90) to obtain better printing effects.

[0054] refer to Figure 5 In this embodiment, the upper surface of the interference block is covered with black (such as C:75, Y:67, M:68, K:90) after the four colors of CMYK are superimposed, that is, the upper surface of the interference block is dark black as a whole. When the user uses black pen and ink to write in this area, since the black color of the written or printed font is not as dark as the black color of the interference block, the handwriting and the color of the interference block are integrated, thereby realizing the hiding of part of the information on the text. At the same time, the information outside the additional layer 2 is not subjected to information fusion processing, and the written or printed information is completely retained and presented. When the user needs to read, memorize or review, he needs to supplement and improve the original information according to the information outside the additional layer 2, thereby achieving the purpose of assisting reading and memory.

[0055] Optionally, the black pigment of the additional layer 2 can also be uniformly mixed with other raw materials such as oxidants, catalysts, solvents, etc. to form an interference reagent coating, and the reagent is evenly applied to the surface of the paper body 1 using a spray gun or a brush to form an interference layer. In the embodiment, sodium hypochlorite (NaClO) or its salts (such as potassium persulfate K2S2O8) are preferably used as oxidants. These oxidants can gradually decompose the organic components in the ink of the user's neutral pen, etc. The catalyst can be certain metal ions (such as iron ions Fe 3 + 、Copper ion Cu 2+) or enzyme catalysts. Adding a catalyst can accelerate the oxidation and decomposition process of the pigment by the oxidant. The solvent can preferably be water, ethanol or a mixture thereof. The solvent can dissolve the oxidant, the catalyst and the black pigment and ensure that they can be evenly applied to the surface of the paper body 1. Some additives can also be added to improve the fluidity, drying speed and adhesion of the coating. The above-mentioned black pigment needs to be compatible with the oxidant to ensure that it can still maintain good color development and stability after mixing with the oxidant. When the user uses other black ink refills to write text on the additional layer 2, the principle is the same as above. In the early stage, when the text or image written or printed by the user falls on the additional layer 2, it merges with the information of the additional layer 2, so that the text or image information on the additional layer 2 is first reduced or loses resolution due to color. Secondly, as time goes by, the text or image information that interferes with the additional layer is gradually decomposed and oxidized over time, and the information in the additional layer 2 area disappears permanently, realizing the hiding of part of the written or printed information, assisting the user's reading and memory.

[0056] Similarly, when a user uses a red pen or a blue pen to write and print text or image information on red or blue interference blocks, the recognizability of the information is reduced or lost, thereby partially hiding the written and printed information, which assists the user in reading and memorizing. Information fusion is achieved for multiple color dots, color lines, color blocks, etc., that is, multiple color dots, color bars, and color blocks are arranged in a certain order or randomly on the additional layer 2, forming interference with the user's written information. When the user finishes writing and reviewing the notes, the resolution of the note information on the additional layer 2 is reduced due to the presence of a large amount of interference information. Even if the user's peripheral vision scans the information of other knowledge points, the user cannot directly distinguish it because there is also a large amount of interference information, forcing the user to give priority to processing the current information to complete the current information, and has no time to take care of other information scanned by the peripheral vision, thereby improving the review efficiency of the current knowledge point.

[0057] Example 4

[0058] refer to Figure 6 and Figure 7 The present embodiment provides a memory-assisting paper, comprising a paper body 1, wherein the paper body 1 comprises a bottom layer 103 and a writing layer 101 stacked on the top of the bottom layer 103, wherein the additional layer 2 is arranged on the upper surface of the writing layer 101, and the back surface of the additional layer 2 on the writing layer 101 is set as a first transfer area 3, and a first developing area 4 is set on the upper surface of the bottom layer 103, and the first developing area 4 corresponds to the first transfer area 3 one by one.

[0059] When the user uses the writing layer alone, if the handwriting outside the additional layer 2 is retained, the note information written within the additional layer 2 will be completely discarded. For simple notes, the prompt information retained outside the additional layer 2 is sufficient to assist memory, but for the first review memory and complex note information, the lost information in the additional layer 2 is not conducive to the user's review memory. Figure 6 In order to retain the lost information in the additional layer 2, the present embodiment displays the written information in the additional layer 2 on the first developing area 4 on the surface of the bottom layer 103 through the transfer area. The first transfer area 3 is located on the back of the additional layer 2 and has the same size and shape as the additional layer 2. The first transfer area 3 is formed by the embossing coating adhering to the lower surface of the writing layer 101. The embossing coating is a microcapsule containing a limin pigment oil or a carbon black coating, and can also be other additional layers containing a colorant, a binder, a filler, a diluent, an anti-skinning agent and a slip agent, so that The first transfer area 3 has the ability to copy, and can copy the handwriting of the additional layer 2 on the first developing area 4 on the upper surface of the bottom layer 103 under pressure. In this embodiment, when printing or writing, the printing needle or the pen head applies pressure to the first transfer area 3 on the back of the additional layer 2, causing the first transfer area 3 to copy the handwriting of the additional layer 2 to the first developing area 4 through the embossing coating, so that the first developing area 4 shows the handwriting. The handwriting of the first developing area 4 complements the handwriting of the writing layer 101, just forming a complete information. The overall writing effect is as follows: Figure 7 As shown, the user can review based on partial information during the later reading review process. The partial loss of original information reduces the influence of peripheral vision on the review of different knowledge points. The forgotten information can be consolidated by viewing another part of the information, thereby achieving the purpose of assisting memory.

[0060] In this embodiment, the embossed coating layer may also be an acid-base color developing layer, which is formed by calcium carbonate or calcium hydrogen phosphate powder, or other acid-base chemical reagent powder. An acid-base indicator is attached to the surface of the first developing area 4, and the acid-base indicator may be phenolphthalein, bromophenol blue, etc. As long as the chemical reagents used in the acid-base color developing layer and the acid-base indicator used are safe and environmentally friendly, and the acid-base color developing layer used can permanently develop color after contacting the acid-base indicator, when writing tools such as pencils, pens or typewriters write on the additional layer 2, the pressure of the pen tip or the print head acts on the embossed coating layer, and the pressed part of the first embossed area reacts chemically with the first color developing area, and the writing result is displayed in the first developing area 4, forming clear handwriting.

[0061] In this embodiment, if the writing is retained on the additional layer, a first embossing area can be provided on the back side of the upper surface of the paper body outside the additional layer.

[0062] Example 5

[0063] refer to Figure 8 and Fig. 9The present embodiment provides a memory-aiding paper, comprising a paper body 1, wherein the paper body 1 comprises a bottom layer 103 and a writing layer 101 disposed on the upper end of the bottom layer 103, wherein a transfer layer 102 is disposed between the bottom layer 103 and the writing layer 101, wherein the additional layer 2 is disposed on the upper surface of the writing layer 101, wherein a first transfer area 3 is disposed on the back of the additional layer 2 of the writing layer 101, wherein a second developing area 5 corresponding to the first transfer area 3 is disposed on the upper surface of the transfer layer 102, wherein a second transfer area 6 is disposed on the back of each second developing area 5 on the transfer layer 102, wherein the bottom layer 103 has an upper surface. A first developing area 4 is provided which corresponds to the second transfer area 6 one by one. When the writing layer 101, the transfer layer 102 and the bottom layer 103 are stacked together from top to bottom, the first transfer area 3 and the second transfer area 6 are staggered and connected, and the first transfer area 3 and the second transfer area 6 overlap with the additional layer 2 or exceed the area where the additional layer 2 is located after being connected. In this way, the information on the additional layer 2 can be printed on the first developing area 4 and the second developing area 5. The method of using this embodiment is the same as that of embodiment 4. During use by the user, the handwriting or image on the additional layer 2 cannot be retained on the upper surface of the writing layer, and only the writing effect of the additional layer is retained. Fig. 9 As described above, the handwriting in the first transfer area 3 is printed on the first developing area 4, and the handwriting in the second transfer area 6 is printed on the second developing area 5. The handwriting in the first developing area 4, the handwriting in the second developing area 5 and the handwriting in the writing layer 101 complement each other to form a complete set of information, wherein the second transfer area 6 is formed by adhering the embossed coating to the lower surface of the transfer layer 102, and the second transfer area 6 is similar to the first transfer area 3. When the embossed coating on the second transfer area 6 is a microcapsule containing a power-sensitive pigment oil or a carbon black coating, the second developing area 5 does not need to be specially treated.
