Description

  In the present invention, when characters of a transfer object (textbooks, reference books, other printed materials) are marked with a colored transparent color, and a colored transparent sheet complementary to the color is overlapped, the marked portion becomes dark, The present invention relates to a learning tool for temporarily concealing, in which the marked portion becomes visible again when the colored transparent sheet becomes unobservable and the colored transparent sheet is removed. Usually, it is used for memorization learning.

  Conventionally, there is one that marks using a writing instrument. For example, as disclosed in Japanese Patent Application Laid-Open No. 57-037389, a learning tool composed of a set of a writing instrument and a colored transparent sheet having a complementary color (rear color) relationship with the color of a portion marked by the writing instrument has been commercialized.

  In writing instruments, problems such as ink color unevenness and ink back-off that penetrates to the back side of the transfer object may occur. Some are marked using a film transfer tool instead of a writing instrument. The coating film is pressure-transferred to characters using a coating film transfer tool, and marked with a coating film. For example, a coating film transfer tool and a pressure-sensitive transfer tape as disclosed in Japanese Patent No. 3547545, Japanese Patent No. 3501433 and Japanese Patent Laid-Open No. 11-048689 are disclosed.

  In addition to these, the coating film transfer tool has various shapes. For example, there are Design Registration No. 1286952 and Design Registration No. 1343631.

JP-A-57-037389 Japanese Patent No. 3547545 Japanese Patent No. 3501433 Japanese Patent Laid-Open No. 11-048689 Design Registration No. 1286952 Design Registration No. 1343631

  These coatings are marked with a solid color like a writing instrument. It is a solid consisting of one color having a complementary color relationship. There was nothing that marked a non-solid pattern that would be a dark concealed pattern that was not visible.

  The problem to be solved by the present invention is to mark a colored transparent coating film with a solid pattern using a coating film transfer tool, and when a colored transparent sheet is overlaid, the dark concealed pattern whose pattern is not visible Is to provide a learning tool. Moreover, it is to be able to remove the coating film by plastic eraser (so-called eraser).

The present invention is a learning tool comprising a set of a coating film transfer tool for pressure-sensitive transfer of a colored transparent coating film having a solid pattern formed on a base tape, and a colored transparent sheet. It consists of a protective layer, a printing layer, and an adhesive layer in order from the material tape. The printing layer has a colored transparent color that is complementary to the color of the colored transparent sheet, and consists of a complementary color and a non-complementary color (non-complementary color). It consists of only the printed part, the printed part is a method of printing dots, and the adhesive layer is a method of applying a liquid adhesive layer coating liquid and forming it by heating and drying, and it is colored transparent with a pressure-sensitive transferred pattern When a colored transparent sheet is superimposed on a coating film, it becomes a concealment pattern which cannot be visually observed.

  Marking with a colored transparent coating film with a solid pattern using a coating film transfer tool, and overlaying a colored transparent sheet, it is possible to provide a learning tool in which the pattern becomes an invisible dark concealment pattern It became so. Further, the coating film can be removed by plastic eraser (so-called eraser). Furthermore, the pattern can be made multicolored, and can be left as a solid pattern of one color without being removed.

It is explanatory drawing which showed the usage example used as an elephant concealment pattern. It is explanatory drawing which showed the usage example used as another concealment pattern. It is sectional drawing of a pressure-sensitive transfer tape without a part without printing. It is explanatory drawing which expanded the printing part printed by the dot. It is a perspective view of a coating film transfer tool (blade-shaped transfer head). It is a front view of an example of using the coating film transfer tool in FIG. Is an explanatory view in opaque housing of the coating film transfer tool in FIG. It is a front view of the coating-film transfer tool (blade-shaped transfer head) with the cap attached. It is a perspective view of a coating film transfer tool (roller-shaped transfer head). Is a front view showing an example of use of the coating film transfer tool in FIG. It is a rear view of FIG. 10. It is an explanatory view transparent front of the housing of the coating film transfer tool in FIG. 10. It is a front view of the coating-film transfer tool (roller-shaped transfer head) which attached the cap. It is explanatory drawing which showed the colored transparent sheet. It is an example of use of the present invention.

  In the present invention, the complementary color is a combination color that becomes dark when a complementary color is superimposed on a certain color. Here, the dark color is a color that cannot be read because the marked character cannot be seen. Overlaying complementary colors results in dark colors that cannot be read and cannot be seen.

  Colored and transparent means that the color is transparent but transparent, and the character can be visually recognized and read even if the character is marked or overlapped.

  A coating film consists of a protective layer, a printing layer, and an adhesion layer in order from a base tape, and the printing layer has a colored transparent color which is a complementary color to the color of the colored transparent sheet. When a colored transparent sheet is overlaid on the coating film, the coating film pattern is changed to a dark-colored concealing pattern that cannot be seen. If the pattern is composed of multiple colors including complementary colors, only the complementary color portion becomes a dark color that cannot be seen, and changes to a concealed pattern. The characters marked by this concealment pattern are temporarily concealed so that they cannot be read.

  FIG. 1 is an explanatory view showing an example of use as an elephant hiding pattern. FIG. 1A shows characters to be marked, which are “Aiueo”. FIG. 1B shows the coating film 1 marked with the coating film 1 by pressure-sensitive transfer of the coating film 1 to the characters of FIG. FIG.1 (c) overlaps a colored transparent sheet | seat on (b).

  Actually, the color is attached, but since the figure is black and white, the color difference is expressed by the shade of black. In many cases, the characters to be marked are words in a sentence, but the words “Aiueo” are used instead of the words.

  In FIG. 1 (b), the colored transparent color that is complementary color 2 to the color of the colored transparent sheet is only the elephant pattern portion, and the color other than that portion is not complementary color 2. Hereinafter, a color that is not complementary color 2 is referred to as non-complementary color 3. In this way, the pattern is composed of multiple colors including complementary color 2 (complementary color 2 and non-complementary color 3). When a colored transparent sheet is superimposed on this, it becomes a dark color which cannot be visually observed, and becomes an elephant concealment pattern. Due to this concealment pattern, the letters “Aiueo” marked on the coating film 1 in FIG.

  FIG. 2 is an explanatory view showing an example of use as another concealment pattern. FIG. 2 is the same as FIG. 1 except for the concealment pattern of FIG. FIG. 2A shows characters to be marked, which are “Aiueo”. FIG. 2B shows the coating film 1 marked with the coating film 1 by pressure-sensitive transfer of the coating film 1 to the characters of FIG. FIG.2 (c) overlaps (b) with a colored transparent sheet.

  The invisible concealment pattern (other concealment patterns) in FIG. 2 (c) renders characters whose height is 20% or more and 100% or less of the concealment pattern width in the tape width direction (vertical direction in the figure) unreadable. It is a hiding pattern that can be.

  In FIG. 2B, the colored transparent color which is complementary color 2 to the color of the colored transparent sheet is only the concealed pattern portion, and the non-complementary color 3 is other than that portion. In this way, the pattern is composed of multiple colors including complementary color 2 (complementary color 2 and non-complementary color 3). If a colored transparent sheet is superimposed on this, it becomes a dark color which cannot be visually observed, and becomes a concealing pattern. Due to this concealment pattern, the mark “Aiueo” marked in FIG. 2C cannot be read.

As shown in FIGS. 1 and 2, the pattern 1 can be multicolored using a non-complementary color 3 instead of a solid color having a complementary color. When a colored transparent sheet is superimposed on the coating film 1, the pattern of the coating film 1 changes to a dark concealed pattern (FIG. (C)) which cannot be visually observed. Further, the non-complementary color 3 can be multicolored instead of one color, and a more colorful pattern can be obtained. The pattern of the present invention is not limited to FIG. 1 and FIG.

FIG. 3 is a cross-sectional view of the pressure-sensitive transfer tape 4. It consists of the protective layer 6, the printing layer 7, and the adhesion layer 8 in order from the base tape 5. FIG . FIG. 3 is a cross-sectional view of the pressure-sensitive transfer tape 4 in which the printing layer 7 is composed only of a printing portion composed of the complementary color 2 and the non-complementary color 3 and has no portion without printing . There is no portion where there is no printing, that is, the portion where the protective layer 6 and the adhesive layer 8 are in direct contact. This cross section does not correspond to the pattern of FIG. 1 or FIG.

In actual production, a protective layer 6, a printed layer 7, and an adhesive layer 8 are formed in order using a wide and long base material, and cut into a fixed width, so that the base tape 5 as shown in FIG. The pressure-sensitive transfer tape 4 is composed of a protective layer 6, a printing layer 7, and an adhesive layer 8 in this order.

  As the base material (base tape 5), a plastic film such as polyethylene terephthalate (PET) or polypropylene, glassine paper, or the like can be used.

  The thickness of the base material (base tape 5) is preferably 3 μm or more and 100 μm or less. If the thickness of the base tape 5 is large, there may be a problem that the pressure to be transferred is not sufficiently transmitted and pressure-sensitive transfer cannot be performed well. On the other hand, if the thickness of the base tape 5 is small, the strength of the tape becomes weak, and problems such as tearing of the tape itself may occur.

  Moreover, it is preferable that the base material (base tape 5) is subjected to double-sided peeling processing. Peeling process consists of silicon resin, fluororesin, other peelable resin or oil as the main component, and if necessary, synthetic resin, fine particles, additives, etc. that do not have peelability are mixed with gravure coating or It is applied by a method such as die coating.

  The protective layer 6 may be made of an acrylic resin, a urethane resin, a polyethylene resin, a polystyrene resin, a melamine resin, an epoxy resin, a thermoplastic elastomer, or the like.

  In the present invention, in order to give the performance of protecting the transferred coating film 1 and being able to be removed by plastic eraser, the protective layer 6 is a mixture of acrylic resin and thermoplastic elastomer. This is a mixture of acrylic resin and thermoplastic elastomer that protects the coating film 1 with appropriate strength for protection and can be removed by plastic eraser in balance with the adhesive layer 8. This is what we found. Here, examples of the thermoplastic elastomer include a styrene-based thermoplastic elastomer (styrene block copolymer), such as a styrene-butadiene-styrene structure, a styrene-isoprene-styrene structure, and a styrene-ethylene / butylene-styrene structure.

  The mixing ratio of the acrylic resin and the thermoplastic elastomer may be 30% by weight or more and 70% by weight or less for the acrylic resin, 30% by weight or more and 70% by weight or less for the thermoplastic elastomer, and 40% by weight for the acrylic resin. % To 60% by weight and the thermoplastic elastomer is more preferably 40% to 60% by weight. As the thermoplastic elastomer, a styrene-based thermoplastic elastomer is preferable in order to satisfy the above performance of protecting and removing the coating film, and among them, a styrene-based thermoplastic elastomer having a styrene-ethylene / butylene-styrene structure is more preferable. .

  In order to prevent the coating film 1 from deteriorating, it is preferable to include an antioxidant such as phenol or phosphorus, and an ultraviolet absorber such as paraaminobenzoic acid, benzophenone methoxycinnamic acid derivative or salicylic acid derivative. Moreover, in order to improve the applicability | paintability on a base material (base tape 5) as a coating liquid, you may contain surfactant, such as anionic property, cationic property, amphoteric, and nonionic property.

  The protective layer 6 can be formed by applying a protective layer 6 coating solution containing these with a so-called coater and drying by heating. In order to obtain the performance as the protective layer 6, the thickness of the protective layer 6 is preferably 1 μm or more and 20 μm or less, and more preferably 3 μm or more and 15 μm or less. If the thickness of the protective layer 6 is small, it cannot withstand the force at the time of pressure-sensitive transfer, and the transferred coating film 1 may be cracked or the pattern may be broken. The performance as can not be. If the thickness of the protective layer 6 is large, problems such as failure to cut well with the transfer head of the coating film transfer tool may occur, and pressure-sensitive transfer cannot be performed.

  The printing layer 7 may be any method as long as it can form a pattern composed of multiple colors including complementary color 2 (complementary color 2 and non-complementary color 3), but printing is preferable for forming the pattern.

Portion having no printing is reduced, that is, between the protective layer 6 when the adhesive layer 8 are in contact area is reduced directly by the difference in adhesive strength between the adhesive layer 8 printed portion, the printed layer 7 and the protective layer 6 In some cases, the problem of peeling off may occur. When there is no unprinted portion as shown in FIG. 3, a problem that the printed layer 7 and the protective layer 6 are peeled off easily occurs.

In order not to cause such a problem, it is preferable that the printed part is a method of printing dots, and the adhesive layer 8 is formed by an adhesive layer coating liquid that is a liquid. For example, gravure printing, screen printing, and ink jet printing are preferable for printing, and the pressure-sensitive adhesive layer 8 is preferably formed by applying a pressure-sensitive adhesive layer coating solution with a so-called coater and heating and drying.

In the method of printing dots, a gap is provided between the dots. Since the pressure-sensitive adhesive layer coating liquid to be applied is a liquid, the pressure-sensitive adhesive layer 8 can be formed by entering the gap. Thereby, even when there is no unprinted portion as shown in FIG. 3 , the protective layer 6 and the adhesive layer 8 have a portion in direct contact with the printed layer 7.

FIG. 4 is an explanatory diagram in which the surface of the printed portion printed with dots is enlarged. This indicates that there is a gap 12 between the points 11 and 11, and the adhesive layer 8 has entered the gap 12. In FIG. 4 , the point 11 is represented by a circle, but may have a shape other than a circle (rhombus or other polygon) depending on the printing method or conditions. In the figure, the void 12 is emphasized and enlarged, but in the actual coating film 1, such a point 11 cannot be seen, and a colored transparent color is obtained.

If the pressure-sensitive adhesive layer 8 is a method in which a liquid pressure-sensitive adhesive layer coating solution is applied by a so-called coater and formed by heat drying, the pressure-sensitive adhesive layer coating solution is formed in the gap 12 between the points 11 and 11 of the printed portion. The pressure-sensitive adhesive layer 8 is formed even in the gap 12, and the protective layer 6 and the pressure-sensitive adhesive layer 8 have a portion in direct contact with the printed portion . In the formation method in which the adhesive layer 8 formed on the release paper or the like is bonded to the printed portion formed on the protective layer 6, the adhesive layer 8 cannot be penetrated in this way, and is peeled off between the printed layer 7 and the protective layer 6. May occur.

  As the adhesive layer coating liquid, an acrylic or vinyl ether synthetic resin or rubber-based material that is generally handled as an adhesive can be used. If necessary, you may mix | blend a filler, an adhesive property modifier, an anti-aging agent, etc.

  In order to obtain sufficient adhesive performance, the thickness of the adhesive layer 8 is preferably 1 μm or more and 20 μm or less. If the thickness is small, sufficient adhesion performance may not be obtained, and there may be a problem that it does not catch on the transfer object. If the thickness is large, the coating film 1 may be cut off when pressure-sensitive transfer is performed, and the coating film 1 may be elongated.

  Not only the print layer 7 but also the colored transparent protective layer 6 or the adhesive layer 8 which is the non-complementary color 3 may be used. Further, the color sensation can be enhanced by using a pearl pigment, lame or the like for the protective layer 6.

  Thus, the pressure-sensitive transfer tape which formed the protective layer 6, the printing layer 7, and the adhesion layer 8 in order using the wide elongate base material was cut | judged to the fixed width, and was wound around the supply reel, and was made into the tape form. 4 is used by being loaded into a coating film transfer tool. The constant width of the pressure-sensitive transfer tape 4 is generally between 2.5 mm and 12 mm, but may have a width other than this.

The feeding reel 16 and the take-up reel 17 have an interlocking mechanism, and the coating film transfer tool 13 uses a gear 18 as the interlocking mechanism. Gears 18 on the supply reel 16 and the take-up reel 17 are interlocked. There is a gear 18 on the back side of the coating film transfer tool 13, and only the gear 18 of the feeding reel 16 is visible in the drawing. Further, the take-up reel 17 has a knurled flange 19 and is visible on the front side of the coating film transfer tool 13 in the drawing. The coating film 1 can be transferred onto the transfer object 24 by pulling from the left side to the right side of the drawing while applying pressure from the base tape 5 side of the pressure-sensitive transfer tape 4 with the blade 20 of the transfer head 15.

  By such a series of movements, the coating film 1 can be pressure-sensitive transferred using the coating film transfer tool 13. That is, it is possible to mark characters or the like of the transfer object 24 with the coating film 1.

  Since the pressure-sensitive transfer tape 4 has a pattern color, a tape remaining amount confirmation unit is provided so that the remaining amount of tape in the coating film transfer tool 13 can be confirmed. In this coating film transfer tool 13, the remaining amount of the tape can be confirmed because the casing 14 is transparent. In the case of such a coating film transfer tool 13, the transparent casing 14 itself is the remaining tape amount checking portion.

  A reel adjustment window 22 is provided so that it can be corrected when the balance between feeding and winding is lost.

Clayton G1701 made by Kraton Polymer, which is an elastomer, is 57% by weight, Irganox 1010 made by Ciba Specialty Chemicals Co., Ltd. is 0.7% by weight as an antioxidant, and Tinuvin P made by Ciba Specialty Chemicals Co., Ltd. is used as an ultraviolet absorber Is 0.3% by weight. What mixed these in toluene as a solvent was used.

  The gravure printing, which is a method of printing dots on this protective layer, uses VS-SANS manufactured by Osaka Printing Ink Manufacturing Co., Ltd. as the gravure printing ink so that the thickness of the elephant of FIG. A printing layer to be a printing pattern was formed. In the elephant print pattern, the color of the portion to be concealed was prepared so as to be a complementary color to the color of the colored transparent sheet. As the colors other than the portion to be concealed, a color that is non-complementary to the color of the colored transparent sheet was used.

  Thereafter, Nicazole TS-1523 manufactured by Nippon Carbide Industries Co., Ltd., which is an acrylic adhesive as a liquid adhesive layer coating solution, is applied with a reverse roll coater and dried by heating, so that the thickness becomes 3 μm. An adhesive layer was formed.

The pressure-sensitive transfer tape, which is cut into a width of 5 mm and a length of 10 m, is wound around a supply reel and formed into a tape shape, is loaded into the coating film transfer tool of FIG. Then, the characters were marked as shown in FIG. 1 (the coating film was pressure-sensitive transferred onto the characters). When the colored transparent sheet by plastic coloring and the colored transparent sheet by ink jet printing were superimposed on the marked characters, both of them became a concealed pattern that was not visible, and the characters could not be read. Moreover, the mark was able to be removed with plastic eraser (Rader manufactured by Seed Co., Ltd.).

  The elephant print pattern of Example 1 can be made illegible for characters whose height is 20% or more and 100% or less of the concealment pattern width in the tape width direction (vertical direction in the figure) as shown in FIG. A printing layer to be a concealed pattern printing pattern was formed. Except this, it is the same as Example 1, and when a colored transparent sheet by plastic coloring and a colored transparent sheet by ink jet printing are superimposed on the characters marked as shown in FIG. However, it became an invisible hiding pattern, making it impossible to read the characters. Moreover, the mark was able to be removed with plastic eraser (Rader manufactured by Seed Co., Ltd.).
