Description

Touch-type display image of the note

The present invention relates to a note, and more particularly to a touch-sensitive display of a note.

Referring to Figures 1 and 2, the general use of the note paper 1 is placed on the table, in the car, by the phone or carried with you. When there is a need to record the call information, communicate the notes, or communicate the assignments, etc. That is, any pen, pen, ball pen, or pencil can be used to write and display an image on the note paper 1 to leave a message.

However, if you want to make an emergency note, you can't record it immediately when there is no pen to write, or if the pen ink is used up, and the pen is used up, so that the general note paper 1 exists in actual use. There is a delay in recording the inconvenience of the message.

Therefore, the object of the present invention is to provide a touch-sensitive display image note that leaves a message without writing with a pen, and the note is not easily generated by collision or friction before being used. And in the process of leaving the message, only the color of the written note is displayed, and the color is not displayed on the next note.

Therefore, the touch-sensitive display image of the present invention comprises a plurality of touch-sensitive color-developing units, each of the touch-sensitive color-developing units overlapping each other, and comprising an upper surface and a lower surface and having a basis weight of 60 g/m ² The above paper body and a color developing layer coated on the upper surface of the paper body, the color developing layer comprising a plurality of microcapsules and a non-carbon color developing material, wherein each microcapsule has a particle diameter of 4.5 μm or less And coating a reactive dye, applying a partial pressure to each touch coloring unit, so that the microcapsules under pressure are crushed to release the reactive dye and combine with the non-carbon color developing material to develop color.

The effect of the invention is that: by the design of the color developing layer, as long as the coloring layer is pressed to rupture the microcapsules at the pressurizing layer, the reactive dye coated in the microcapsules is released and non-carbonized. After the color materials are mixed and developed, the purpose of displaying the message can be achieved, that is, the finger can be used to touch the color layer with a finger, a coin, or any other pointed object that can be obtained by hand. Under the coloring effect, the color developing layer can be colored to leave an image message, which is quite convenient to use.

The above and other technical contents, features and advantages of the present invention will be apparent from the following detailed description of the preferred embodiments of the invention.

Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figures 3 and 4, a first preferred embodiment of the touch-sensitive display of the note 2 of the present invention comprises a plurality of stacked touch-sensitive color-developing units 3. As shown in FIG. 4, each touch color-developing unit 3 includes a paper body 31 having an upper surface 311 and a lower surface 312, a color-developing layer 32 coated on the upper surface 311 of the paper body 31, and a a first adhesive layer 33 applied to one end of the lower surface 312 of the paper body 31. The color developing layer 32 is a plurality of microcapsules 321 coated with a reactive dye and having a particle diameter of 4.5 μm or less, and a non-carbon display. A mixed layer of color materials 322.

The touch color development unit 3 is configured to be adhered to each other through the first adhesive layer 33. Wherein, the first adhesive layer 33 is a pressure-sensitive adhesive, so that the note 2 is a re-displaceable self-adhesive note, and can be repeatedly attached to the surface of any object, and each touch is displayed. The paper body 31 of the color unit 3 has a basis weight of 60 g/m ² or more, and preferably, the paper body 31 of each of the touch color-developing units 3 has a basis weight of 70 to 120 g/m ² .

The coating amount of the microcapsules 321 in the color developing layer 32 is 0.5 to 6.0 g/m ² , and preferably, the particle diameter of each of the microcapsules 321 is 2.0 to 4.5 μm, and more preferably, the coating of the microcapsules 321 is performed. The amount is 1.8 to 3.0 g/m ² .

Each microcapsule 321 includes a housing 323 with a reactive dye encased within the housing 323. The composition of the outer casing 323 is selected from aminoplast or gelatin, the reactive dye is crystal violet lactone (CVL), and the non-carbon chromogenic material 322 is selected from phenolic resin. (Phenolic Resin), Active clay or Salicylic type resins.

Referring to FIG. 4, when the note 2 is to be used, as long as the coloring layer 32 is pressurized to break the microcapsules 321 at the pressurization, the reactive dye coated in the microcapsules 321 is released and non-carbon. The color developing material 322 is mixed and developed to achieve the purpose of displaying a message. Of course, the user can also write the message directly on the color rendering layer 32 with any pen, but if the pen is temporarily not found in the car, by the phone, or on the desk, or the ink is exhausted, there is no refill. In all kinds of cases, it is not necessary to use a pen, ink, or any other hand-picked material with a certain hardness or a sharp object to touch the color-developing layer 32, that is, without using a pen Under the coloring, an image message can be left on the color developing layer 32, which is quite convenient to use.

Referring to FIG. 5, by the limitation of the basis weight of the paper body 31, in the process of leaving a message, only the writing touches the color developing unit 3 to develop color, and the applied pressure is dispersed and reduced to be insufficient. The next adjacent one touch color developing unit 3 develops color. In this embodiment, a plurality of stacked touch color-developing units 3 are taken as an example. Of course, only one touch-sensitive color-developing unit 3 can be used alone, and is not limited thereto.

In the following experimental examples, different basis weights of the paper body 31 (Experimental Example 1), different particle sizes of the microcapsules 321 (Experimental Example 2), and different coating amounts of the microcapsules 321 (Experimental Example 3) )conduct experiment.

Experimental example one

This experimental example was tested with two adjacent stacked touch color developing units 3 of the note 2, wherein the microcapsules 321 had an average particle diameter of 2.7 μm and coated with crystal violet lactone (CVL). The microcapsule 321 is preferably applied in an amount of 1.8 to 3.0 g/m ² .

Referring to U.S. Patent No. 4,087,736, the color rendering effect of non-carbon carbon paper is tested by typewriter test. The present invention tests different basis weights by model Epson LQ-2080C list machine (40, 60, 80, 100, 120 g, respectively). /m ² ) The color development effect of the paper body 31, the lister simultaneously tests the two touched color-developing units 3 with the typewriter, and uses the Tokyo denshoku model TR-600 color difference meter (Whiteness Reflectometer Model TR-600) The whiteness value was measured (U.S. Patent No. 4,784,982 to measure the whiteness value by this type of color difference meter). It should be noted that the whiteness value measured by the existing white paper is 83.

As shown in the following list 1, the touch coloring unit 3 including the paper bodies 31 having different basis weights is used to perform a typewriter and measure the whiteness value thereof, wherein the number of hitting fields of the typewriter is tested by the scale 0, and after the test, the scale 0 is Force is the closest to the power of ordinary people to write. The higher the whiteness value, the less obvious the coloration, and the lower the whiteness value, the more obvious the coloration; the whiteness value above 70 is the poor color development, and the lower than 70 is the color development. As a result, both in the vertical measurement and the next day, when the basis of the paper body 31 is greater than or equal to 60 g/m ² , the whiteness value of the second sheet is greater than 70. That is to say, when the note body 2 of the paper body 31 having a basis weight of 60 g/m ^{2 or more} is designed, the color of the pressed color-developing unit 3 can be developed only under the pressure, and the touch is not adjacent to the lower side. The color is developed on the color developing unit 3.

Experimental example 2

In this experimental example, a static pressure test was performed on the touch color developing unit 3 coated with microcapsules 321 having different particle diameters (2.144 μm, 2.740 μm, 3.574 μm, 4.467 μm, 5.269 μm, 6.262 μm, respectively), each touch The collision coloring unit 3 is a paper body 31 having a basis weight of 80 g/m ² , and a preferred coating amount of the microcapsules 321 is 1.8 to 3.0 g/m ² .

As shown in Table 2, after static pressure for 5 minutes at 5kgf/cm ² and 7kgf/cm ² , the whiteness value after static pressure is measured by a color difference meter to deduct the whiteness value before static pressure, and the whiteness difference and whiteness are obtained. The closer the difference is to 0, the lower the degree of contamination of the paper. The higher the negative value, the higher the degree of contamination of the paper. The negative value of less than -2 indicates that there is obvious pollution. If the negative value is greater than -6, the pollution is representative. Acceptable (particle size below 4.5 μm), if the negative value is greater than -2 (particle size less than 2.8 μm), it means almost as uncontaminated. The results show that as the particle size of the microcapsules 321 is larger, the negative value of the measured whiteness difference is higher, and the preferred particle diameter is 2.740 μm or less. In other words, the microcapsules 321 having a smaller particle diameter are less likely to be subjected to pressure cracking than the particle diameters, so the notes 2 designed with the microcapsules 321 having a small particle diameter are not easily rubbed by friction before being used. And color.

Experimental example three

In this experimental example, microcapsules 321 account for different proportions of the coating (or chromogenic layer 32) (5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, respectively). The touch coloring unit 3 performs a typewriter test and a static pressure test. The basis weight of the paper body 31 of each of the touch color developing units 3 is 80 g/m ² , and the particle diameter of the microcapsules is 2.7 μm.

As shown in Table 3, the whiteness value above 70 is defined as the poor color development, and below 70, the color development is good. Among them, CB (Coating Back) represents the coating amount multiplied by the percentage of microcapsules. The results show that when the proportion of the microcapsules 321 is less than 30%, the color development effect of the pressed color-developing unit 3 is not good (the whiteness value is higher than 70); if the ratio of the microcapsules 321 is higher than 50%, The adjacent touch color-developing unit 3 located under the pressure-sensitive touch color-developing unit 3 has a remarkable color development (whiteness value lower than 70). Therefore, the preferred ratio of the microcapsules 321 to the coating material should be between 30% and 50%, and the coating amount of the microcapsules 321 is preferably from 1.8 to 3.0 g/m ² . In the test of static pressure of 7 kgf/cm ² , it was shown that when the ratio of the microcapsules 321 was higher than 50%, there was significant contamination after static pressure (negative value was greater than the defined value -2).

Referring to Figures 6 and 7, a second preferred embodiment of the touch-sensitive display of the note 2 of the present invention is substantially similar to the second preferred embodiment described above, except that the note 2 further includes a plurality of The stacked writing units 4, as shown in FIG. 7, each writing unit 4 includes a note paper 41 having an upper surface 411 and a lower surface 412, and a second adhesive applied to the lower surface 412 of the portion of the note paper 41. The touch layer 42 and the writing unit 4 are adjacent to each other through the corresponding first adhesive layer 33 and the second adhesive layer 42, and the first and second adhesive layers 33, 42 are all using pressure sensitive adhesives.

In the above manner, the touch color-developing unit 3 is adhered to the back surface of the writing unit 4. In the case where the writing tool is generally usable, the pen can be directly written on each note paper 41 by writing, after writing It is also possible to tear off each note paper 41 by adhering the corresponding second adhesive layer 42 to the surface of any article. When the pen cannot be found temporarily, or the ink or the refill is used up during writing, Turning the writing unit 4 over and directly applying pressure on the color developing layer 32 of the uppermost touch display unit by using the above-mentioned pen, finger, or any readily available item, and also achieving color development. And leave the function of the message.
