Description

Print Sheet for Education or Game {Print Sheet for Education and Game}

The present invention relates to a sheet as a whole, and more particularly, by using a temperature-sensitive pigment that can change the shape of the visually perceived pattern according to the temperature of the human body and the touch means in contact. The present invention relates to a printing sheet that can be utilized as a textbook for learning, a card game, and the like.

Nowadays, a variety of teaching materials, cards, and so-called tickets for infants and children are widely used. Among the textbooks for infants and children, a language textbook is used to describe, for example, a simple depiction of a creature such as an animal or a plant or an item easily accessible in the surroundings of the life, or a photographic image of the photograph taken. Creatures or objects depicted on the right, left, or top or bottom of a picture or photograph are displayed in alphabets such as Korean or English to improve the language skills of young children and children.

In addition, in the case of teaching materials for improving the numeracy ability of an infant or a child, for example, "8" indicating a correct answer on a page (question page, first page) where only the question is displayed, such as "5 + 3". The mark is usually printed on a separate page (answer page, second page).

On the other hand, for example, if a card game is easily divided according to who plays a high number, for example, among the card games that children easily encounter, the opponent recognizes the hand that is played in each round. It is common practice to judge a game by placing the back with the same pattern faced upwards, ie, turning the card upside down, and after all the cards have come out, again checking the front of the card with a certain number printed on it.

However, in the conventional sheet for teaching materials for infants or children as described above, all the information is printed on the front surface in advance, and all of this information is described in the form of a constant pattern without change, so that children or infants can easily get tired of it. I tend to pay. In addition, in order to know the correct answer in the textbook for improving the ability to repair, there was an inconvenience, such as refer to a page indicating a separate correct answer in addition to the page on which the problem is displayed.

In addition, even in the card game described above, the inconvenience of having to flip the hand several times was inevitable.

The present invention is proposed to solve the problems of the prior art described above, an object of the present invention is to provide a printing sheet for education or games developed for infants or children, which can induce the interest of infants or children. It is.

Another object of the present invention is to provide a printed sheet that eliminates the inconvenience of having to look for a separate page in order to know the correct answer when using it as a textbook, while eliminating the inconvenience of having to flip his hand frequently for the game. It is.

Other objects and advantages of the present invention will become more apparent from the following drawings and the configuration of the present invention.

The present invention having the above object is a printing sheet made of paper or plastic, and a base layer made of paper or plastic; A first printed layer printed on an upper surface of the base layer; A second printing layer printed on the upper surface of the first printing layer and printed with a thermosensitive pigment so that the printed pattern disappears by contact with the touch means having the same temperature as the body temperature of the human body and the human body; The pattern formed on the first printed layer is not visually recognized due to the pattern shape of the second printed layer until the human body and the touch means contact the printing sheet, but the human body and the touch means contact the printing sheet and the second As the pattern formed on the printed layer disappears, a pattern formed on the first printed layer may be visually recognized.

In this case, the coating layer of a transparent or semi-transparent plastic material laminated on the upper surface of the second printing layer, the adhesive layer adhered to the bottom of the base layer, and a release paper layer attached to the bottom of the adhesive layer may be further included.

In addition, the second printing layer is characterized in that printed by the ink containing a Zion pigment.

In the present invention, the pattern of letters and / or pictures, etc., printed on the upper surface disappears by contact of a touch means such as a writing instrument having a temperature similar to the body temperature of the human body or the human body. It is proposed a printing sheet configured to reveal patterns of characters and / or pictures that could not be detected, that is, concealed.

When the sheet of the present invention is used as a textbook for children or toddlers or a textbook for improving numeracy, the toddler or the child may have a considerable interest from changing the pattern form according to their contact.

In addition, children and infants must use their hands to touch the textbook to see the part that shows the correct answer, so the active learning ability can be improved, and there is no need to go to a separate page to check the correct answer. .

In addition, even when using the printing sheet of the present invention, such as a card game for children or infants, titles, etc., it is not necessary to turn over the face on which the plaque is printed many times to hide its plaque.

The present inventors have endeavored to develop a printing sheet for solving the above-described problems of the prior art, and then, using a pigment having a different visually recognized degree such as color disappearing at a specific temperature, a pattern such as a letter or a picture is used. The present invention has been completed by focusing on the fact that the conventional problems can be solved when printing. The form and use state of the printing sheet according to the present invention will be described with reference to the accompanying drawings.

1 is a cross-sectional view showing a schematic form of a printing sheet that can be used as an educational textbook, for example, according to an embodiment of the present invention. As shown in Figure 1, the printing sheet 100 according to an embodiment of the present invention, the base is formed from the bottom surface 110 and the upper surface of the base layer 110, for example in the form of a film The first printed layer (lower printed layer) 120, the second printed layer (top printed layer 130) formed on the upper surface of the first printed layer 120, and the coating layer formed on the upper surface of the second printed layer 130. 140.

Here, the base layer 110 forms the basis of the printing sheet according to the present invention, and may be made of an olefin resin, a vinyl resin, or the like as a synthetic resin in the form of a paper material or a film, if necessary. Specifically, in connection with the present invention, the base layer 110 may include, for example, polyethylene, such as paper or cloth, as well as polyvinyl chloride (PVC), polyvinyl acetate (PVA), low density polyethylene (LPDE), and linear low density polyethylene (LLDPE). PE, polyethylene), polypropylene, ethylene vinyl acetate (EVA), acrylonitrile-butadiene-styrene (ABS) resins, polystyrene, polyester, thermoplastic polyurethane (TPU), nylon and their Films of synthetic plastic material such as mixtures can be used.

On the other hand, the first printed layer 120 is formed on the upper surface of the base layer 110 using a general ink containing a common pigment that can always be visually detected regardless of the ambient temperature. The pattern that may be represented by the first printed layer 120 may include a pattern such as a picture as well as a predetermined number or letter. The method for printing the first printed layer 120 on the upper surface of the base layer 110 is not particularly limited. For example, various methods such as silk (printing) printing, offset printing, and transfer printing may be used.

Next, the second printed layer 130 printed on the upper surface of the first printed layer 120 will be described. Unlike the first printed layer 120, the second printed layer 130 is printed with ink using a 'temperature sensitive' pigment that can change color due to the appearance and disappearance of color as the temperature changes. The change in color with such an ambient temperature is what is known as a thermochromic pigment or a heat-sensitive pigment, a so-called thermochromic pigment.

Accordingly, a pattern (first pattern) such as a character or a picture displayed on the first printed layer 120 formed on the bottom surface of the second printed layer 130 may be displayed on the second printed layer 130. If the pattern (second pattern) as shown in the figure does not disappear, that is, it is concealed by the second printing layer 130 at normal room temperature and is not visually recognized, it is similar to a specific part of the human body such as the hand or the body temperature of the human body. As the second pattern printed on the second printed layer 130 disappears by a touch means such as a writing instrument heated by the temperature condition, the first pattern printed on the first printed layer 120 may be visually recognized. Can be.

Here, the Zion pigment blended with the ink for forming a constant pattern to the second printing layer 130 has a color inherent below the reference temperature (colored) and becomes a pigment that becomes transparent above the reference temperature. When the reference temperature is largely reached, the color begins to disappear, and when the reference temperature is reached, the color disappears completely and then when the temperature falls again, it is divided into a reversible zion pigment and a non-reversible zion pigment. Reversible Zion Pigment is used.

In connection with the present invention, it is possible to use one or more kinds of Zion pigments whose color is changed by contact with the touch means set to the human body or the body temperature range of the human body. For example, a Zion pigment having a reference temperature of 31 ° C. such as “YT-31 (Yellow thermochromic pigment)” which is a yellow Zion pigment or “OT-31 (Orange thermochromic pigment)” which is an orange Zion pigment is a pigment at 33 ° C. or 35 ° C. The color of the color is completely lost and is not visually recognized, but when the temperature is lowered again, the original color is visually recognized.

As such, by using a Zion pigment whose color is changed using a specific temperature of the human body, for example, the temperature range of the hand, as a reference temperature, the second pattern of the second printing layer 130 is usually left without disappearing and thus the second Only the second pattern of the printed layer 130 is visually recognized and the first pattern of the first printed layer 120 is concealed and not visually recognized, but if a child or toddler touches or rubs the sheet of the present invention, When contacted by the method, the pattern of the second printed layer 130 disappears, and the first pattern of the first printed layer 120 formed on the bottom surface of the second printed layer 130 may be visually recognized.

At this time, the color of the Zion pigment, which changes in color depending on contact and reaction with a touch means set in a temperature range similar to the human body and / or the body temperature of the human body, is a silk screen method or a gravure printing method in the form of a transparent ink. Can be printed using an offset printing method, a transfer printing method, or the like. At this time, the transparent ink composition containing the Zion pigment according to the present invention includes a silver complex compound which is a silver compound as a transparent ink component; Solvent components which are organic solvents such as amines or alcohols (eg methanol, ethanol); Polymer binders (binders) such as acrylic, cellulose, polyester, polyether, vinyl, urethane, alkyd resin, silicone resin; Other additives such as reducing agents, other colorants, surfactants may be blended in any proportion.

Generally, Zion pigments are used in powder form, and in the case of using powder type Zion pigments, they may be contained in the solvent composition in an amount of about 5.0 to 30% by weight, and in the case of non-solvent types. It is mixed at a ratio of approximately 3.0 to 15% by weight. In contrast, emulsion type Zion pigments are mixed in the ink composition at a ratio of approximately 6-30% by weight, and master-batch type Zion pigments may be used at a ratio of 1.0-4.0% by weight.

On the other hand, the coating layer 140 is formed on the uppermost layer of the printing sheet 100 according to an embodiment of the present invention in order to prevent the second pattern, etc. formed on the second printing layer 130 is easily changed. 2 is laminated on the upper surface of the printed layer (130). In the present invention, the coating layer 140 formed on the second printing layer 130 is made of a transparent or translucent plastic material, for example, thermoplastic polyolefin such as polypropylene, polyethylene, heat resistant, polyethylene terephthalate, or the like. In particular, it may preferably be made of aromatic polypropylene (OPP) or cast polypropylene (PPP) or the like.

Meanwhile, a printing sheet having a form different from that described above is also possible, and FIG. 2 is a sectional view showing a schematic form of a printing sheet manufactured in a sticker form according to another embodiment of the present invention. Since only the reference numerals are different for the same configuration as described in FIG. 1, detailed descriptions are omitted. The printing sheet 200 according to another embodiment of the present invention is the first printed layer 220, the second printed layer 230 formed in a form that is sequentially stacked on the base layer 210, the upper surface of the base layer 210. ) And the coating layer 240, as well as the adhesive layer 250 and the release paper layer 260 are formed on the bottom of the base layer 210 for use as a sticker.

At this time, the adhesive layer 250 is attached to the bottom surface of the base layer 210 formed on the top. As the pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer 250, for example, an acrylic resin pressure sensitive adhesive, a rubber pressure sensitive adhesive, or the like may be used. Such pressure sensitive adhesives are well known to those skilled in the art.

In addition, when a release paper layer 260 is attached to the bottom of the adhesive layer 250 so that the adhesive layer 250 is not attached to another article before the printing sheet 200 is attached, the adhesive sheet 250 is actually attached and used. By removing the release paper layer 260 from the adhesive layer 250 in the storage and transportation of the printing sheet 200 can be facilitated. Examples of the material forming the release paper layer include a release paper manufactured by applying a silicone resin emulsion to one or both sides of a kraft paper.

Next, the use state of this invention is demonstrated. 3A and 3B are exemplary use states in which the printing sheet according to the present invention is utilized, for example, the printing sheet of the present invention is used as a textbook for improving the vocabulary for the object depicted by the drawing. The case is illustrated. First, as shown in FIG. 3A, a pattern represented by the second printing layer 330 formed under the coating layer of the printing sheet 300, as an example, may be visually recognized only as an apple.

The second printed layer 330 is printed with an ink containing a temperature sensitive Zion pigment such that the pattern disappears as the temperature changes, for example, as the infant or child contacts by rubbing the sheet 330 by hand. It is. The pigment for printing the second printing layer 330 is a Zion pigment whose color disappears in the human body temperature range as described above, for example, 33 ° C. or 35 ° C., such as “YT-31” or “OT-31”. Below the reference temperature, the color of the pigment is visually recognized, but at higher temperatures, a Zion pigment is used in which the color disappears. Accordingly, when the infant or child contacts the print sheet 300 using a hand or a separate touch means, the pattern of the second printed layer 330 disappears and is formed on the bottom of the second printed layer 330. The word “apple”, which is a Korean word for the shape illustrated as a pattern of the first printed layer 320 that is normally concealed, for example, the pattern of the second printed layer 330, appears (FIG. 3B). In the drawing, the Korean word 'apple' is printed as a pattern of the first printed layer 320, but the English alphabet 'Apple' may be printed as the pattern of the first printed layer 320. Of course.

4A and 4B are diagrams illustrating another exemplary use state in which the printing sheet according to the present invention is utilized. In the printing sheet 300 according to the present use state, the pattern of the second printing layer 330 is different. It is a Korean word "apple", and as the infant or child contacts this sheet 300, the pattern of the second printed layer 330 disappears, and as a pattern of the first printed layer 320 printed on the bottom surface, the second 3A and 3B are identical except for the word “Apple”, which is an English alphabet corresponding to a pattern displayed in Korean on the printed layer 330.

In such use, infants and / or children, when used as textbooks to improve vocabulary skills of infants and / or children, may change visually perceived pattern shapes as the infants and / or children come into contact with the printed sheet. It can cause interest. In particular, as the user contacts, visually recognizes that the pattern of the first printed layer 320 appears in correspondence with the pattern of the second printed layer 330 that appeared originally and the pattern of the first printed layer 320. Since it is naturally known that the pattern 330 of the second printed layer corresponds, the vocabulary ability of the infant and / or the child may be improved more efficiently.

On the other hand, Figures 5a and 5b is a view showing another exemplary use state in which the printing sheet according to the present invention is utilized, respectively, is a textbook for infants and / or children similar to the above, but as a textbook for improving the repair ability It shows the state utilized.

In the printing sheet 400 according to the present use state, as shown in FIG. 5A, the letter “5 + 3” corresponding to the question is formed on the upper part of the pattern of the second printing layer 430, so that the second time is normally used. Only the pattern of the printed layer 430 appears. If an infant and / or a child rubs the print sheet 400 by hand or touches it using touch means such as a writing instrument processed at an appropriate temperature, the pattern of the second printed layer 430 corresponding to the question is Disappears, and the correct answer number "8" corresponding to the question that was the pattern of the first printed layer 420, that is, the pattern of the second printed layer 430, concealed by the second printed layer 430 may be visually recognized. have.

When the printing sheet 400 according to the use state is used as a textbook for improving the repair ability, the infant and / or the child do not need to find a separate page in order to know the correct answer by active contact method by hand. You can see the answer. Accordingly, not only the inconvenience of knowing the correct answer can be reduced, but also the infant and / or child can actively learn the effect because the infant and / or the child must know the correct answer only by actively contacting the print sheet 400. On the other hand, the visually changing pattern forms can be interesting.

6A and 6B are diagrams illustrating still another exemplary use state in which the printing sheet according to the present invention is utilized, respectively, showing a state in which the printing sheet of the present invention is utilized as a game card familiar to children. . In the example of the present use state, as an example of an ongoing card game, it is assumed that a player who wins a high number in each game round wins.

First, as shown in Fig. 6a, the first child who wishes to enjoy a card game presents a card hand 500a employing a printing sheet according to the present invention, and the second child who is the opponent presents another card hand 500b. It is a state. Conventionally, in this type of card game, the card hand chosen by the player had to be flipped so that the opponent could not see it. However, in this use state, the pattern 530 of the second printed layer on the dark background color is the top surface of the card pattern printed pattern (ie, the pattern of the first printed layer, see 520 of FIG. 6B). , 500b) is printed on the upper surface of the print pattern 520.

Accordingly, since no pattern of a card is printed on the front of each card hand 500a, 500b, it is not necessary to flip the card to hide the number or the pattern of the card presented by oneself. Subsequently, after every child presents his or her hand, each child uses the first printed layer 520 that was printed on the front of the card hand that he presented by rubbing the hand. You can check it. In the figure, six diamonds are drawn on the card hand presented by the first child, and three spades are drawn on the card hand presented by the second child, so the first child may be considered to have won. In this state of use, you can avoid flipping a card multiple times to hide your hand, as well as contacting the card to check the pattern of your hand, avoiding the monotony of the game, making the game more fun and fun. It can be planned to proceed.

In the above description of the present invention based on the preferred embodiment of the present invention, those skilled in the art to which the present invention pertains various modifications and changes based on the above-described embodiments can be easily thought. However, all such modifications and variations fall within the scope of the present invention, which will become more apparent through the appended claims of the present invention.
