Description

  The present invention relates to a mount for a frottage technique that is used for coloring or information presentation using the frottage technique.

Traditionally, as a coloring book set, a coloring book set for a copy of a Buddhist painting, a set of a coloring sample with colored Buddha paintings, a base with a sketch of the outline of a Buddhist painting, and a pattern underlay with at least one side of the pattern. (For example, refer to Patent Document 1).
Utility Model Registration No. 3071839

  However, in the coloring book set, the mount and the underlay are facilitated separately, and these are superimposed to draw the coloring picture. For this reason, the overlay position is easy to shift, and once applied at the shifted position, even if the overlay position is corrected, the exposed pattern may protrude from the normal position or overlap with the previously applied exposed pattern. There was a problem of being doubled.

  Therefore, an object of the present invention is to provide a mount for a frottage technique that prevents the overlay position from shifting and prevents the protrusion of the exposed pattern and the double expression.

The present invention takes means (1) to (9) to solve the above-mentioned problems.
(1) That is, the mount for the frottage technique of the present invention has a cover layer 1 on which the writing material rubbed against the surface can be fixed by rubbing the surface with a writing material, and an underlay that is thicker than the cover layer 1 and has a higher surface hardness A multilayer is formed in advance by contacting the layer 2, and a contour and / or frame-shaped print 10 is applied on the surface of the cover layer 1, and finely on the contact surface of at least one of the cover layer 1 or the underlay layer 2. A pattern of the convex structure 3 is formed.

  (2) In the mount for the frottage technique, the cover layer 1 is formed by printing a pattern of the fine convex structure 3 on the contact surface with the underlay layer 2, and in the mount for the frottage technique, the underlayer 2 is The entire contact surface with the cover sheet layer 1 is preferably a flat surface.

  That is, the pattern of the fine convex structure 3 is not printed on the contact surface, and can be drawn by the frottage technique only by the pattern of the fine convex structure 3 obtained by printing the back surface of the cover layer 1.

  The adhesive layer 4 is uniformly applied and formed on the entire surface of the contact surface with substantially the same thickness, and the adhesive layer 4 is bonded to the back surface of the cover layer 1 on which the pattern of the fine convex structure 3 is formed. As a result, the layers are stacked. For example, the cover layer 1 has an information display frame or a drawing outline printed on the front surface and a pattern of the fine convex structure 3 formed on the back contact surface.

  (3) In any one of the above mounts for the frottage technique, the cover layer 1 and the underlay layer 2 are bonded to each other through the adhesive layer 4, and the adhesive layer 4 is a flat contact on which at least the pattern of the fine convex structure 3 is not formed. It is preferably formed by being applied to a region between the contact surfaces, that is, at least a flat region excluding a pattern region of the fine convex structure 3.

  As an example of such a configuration, as shown in FIGS. 2 and 6, an adhesive layer 4 is formed on the contact surface of the flat underlay layer 2 over the entire surface so as to have a substantially equal thickness. That is, in FIG. 2 (Embodiment 1 described later) and FIG. 6 (Embodiment 3 described later), the underlayer 2 having both flat surfaces and the flat contact surface on one side or both sides of the underlayer 2 are approximately equal in thickness. A layer is formed from the formed adhesive layer 4 and a cover layer 1 that is bonded and formed so that the fine convex structure 3 contacts the adhesive layer 4. The cover layer 1 has a fine convex structure 3 formed on the contact surface on the back surface, and is attached to the underlay layer 2 with an adhesive applied to the underlayer 2. This is due to the combination of the configurations of (2) and (3). The cover layer 1 is formed by printing a pattern of the fine convex structure 3 on the contact surface with the underlay layer 2, and the underlayer 2 The above-mentioned frottage, in which the entire contact surface with the cover layer 1 is a flat surface, and the adhesive layer 4 is formed on the entire contact surface of the underlay layer 2 with a substantially equal thickness and adhered to the contact surface of the cover layer 1. A technical mount.

  (4) Moreover, in any one of the above mounts for the frottage technique, the pattern of the fine convex structure 3 is preferably formed by screen printing of photopolymerized ink applied to the contact surface.

  (5) In any one of the above mounts for the frottage technique, it is preferable that the cover layer 1 is formed by adhesion on both sides of the underlay layer 2 so that a pattern can be displayed on both sides.

  In this case, the first cover layer 1, the underlay layer 2, and the second cover layer 1 are formed in advance in order, and these three layers have a laminated structure with the two adhesive layers 4 interposed therebetween. Since the layers are formed in advance by adhesion, a double-sided pattern display mount can be easily obtained. A plurality of mounts for the frottage technique with different prints 10 are prepared, and the common sides can be spelled to obtain a booklet-like one.

  Moreover, in the mount for the frottage technique of (5) above, the pattern of the fine convex structure 3 is printed on the contact surface of the underlayer 2 on the front and back cover layers 1, and the underlayer 2 is flat on both sides. It is preferable. If it is such, the double-sided frottage mount can be obtained as one page without causing product loss. In addition, when the underlay layer 2 that is the central layer is flat, it is difficult to be affected by the fine convex structure 3 on the back side that is not related to the pattern expression when the frottage pattern is exposed. Pattern expression is possible.

  (6) In any one of the above mounts for the frottage technique, the convex structure height 3h of the fine convex structure 3 is preferably larger than the thickness of the adhesive layer 4 and larger than the thickness of the cover layer 1. By being larger than the thickness of the adhesive layer 4 and the thickness of the cover layer 1, the frottage pattern can be surely exposed by simply painting and rubbing the writing instrument.

  In addition, the convex structure height 3 h of the fine convex structure 3 can be larger than the thickness of the adhesive layer 4 and smaller than the thickness of the cover layer 1. In such a case, the cover layer 1 is not damaged during transportation or rubbing of the writing material by being laminated in advance, and the cover layer 1 is not easily broken.

  (7) Further, in any one of the above mounts for the frottage technique, the fine convex structure 3 may have a mountain-shaped top portion in which the central portion in the convex structure width 3w direction bulges by a predetermined bulge amount from both ends. It is preferable for reliable pattern expression by the frottage technique.

  In addition to the above, the height of the both end portions is preferably larger than the thickness of the adhesive layer 4, and in particular, in the fine convex structure 3, the bulging amount at the center portion in the convex width direction is the height of both end portions. It is preferable that it is more than half of the above for stable pattern expression by the frottage technique.

  By taking the above-described means, it is possible to provide a mount for the frottage technique that prevents the overlapped position from being shifted and can reliably prevent the protrusion of the exposed pattern and the double expression.

  The best mode of the present invention will be described below with reference to each of the drawings. FIGS. 1 to 3 show a mount for the frottage technique of Example 1, FIGS. 4 and 5 show Example 2, and FIGS. 6 and 7 show Example 3. FIG. The mount for the frottage technique of the present invention basically includes a cover layer 1 that can be rubbed with a writing material, an underlay layer 2 that is thicker than the cover layer 1 and has a higher surface hardness, and an adhesive layer 4 interposed therebetween. It is a multi-layer forming board made of And the pattern of the fine convex structure 3 is formed in the contact surface of at least one of the cover layer 1 or the underlay layer 2. Since the cover layer 1 and the underlay layer 2 are in contact with each other on the contact surfaces and formed in advance in multiple layers, the frottage technique can be drawn more easily. Hereafter, each structure of an Example is explained in full detail.

  FIG. 1 shows an overview of the mount for the frottage technique according to the first embodiment of the present invention, in which the cover layer 1 is partially peeled off, and FIG. 2 shows a partial sectional structure in a side view. An example overview is shown in FIG. In Example 1, as shown in FIGS. 1 and 2, the front cover layer 1 on which the print 10 is formed on the front surface and the pattern of the fine convex structure 3 is formed on the back contact surface, and the flat contact surface on the front surface are adhered. The underlay layer 2 in which the layer 4 is formed to have a substantially equal thickness is previously formed by adhesion. Since the fine convex structure 3 is directly formed on the back surface of the cover layer 1, the printing and the frottage pattern do not shift, and the product loss due to the displacement of the bonding position of the pattern underlay layer 2 does not occur. Further, since the adhesive layer is formed on the flat contact surface, it is easy to apply the adhesive evenly, and it is possible to obtain a mount for the frottage technique that is securely bonded.

(Cover layer 1)
The front cover layer 1 is a layer that is rubbed with a writing material to perform frottage drawing, and is not limited to the front cover of the mount for the frottage technique, and forms at least one of the front and back, or both sides. The rubbed writing material is moderately caught and dispersed and fixed on the surface, and has a surface on which a painting-like friction drawing can be performed, and a back surface of the contact surface that contacts the underlay layer 2.

  On the surface of the cover layer 1, a drawing contour as shown in FIG. 1 and an information display frame print 10 as shown in the left page portion of the upper diagram of FIG. 6 are formed. The outline can be a Buddha image in addition to various general paintings such as animal pictures as in the first and second embodiments (FIGS. 1 to 5). By forming the contour printing 10, the frottage technique can be surely drawn by the night painting method in the manner of coloring. In addition, as shown in FIG. 6, by forming a frame print 10 for displaying information, it is possible to display hidden characters and the like from the blank frame.

The back surface of the cover layer 1 serves as a contact surface that contacts the underlay layer 2. In the first and third embodiments, the contact surface of the cover layer 1 is formed with a pattern of the fine convex structure 3, and in Example 2, the entire surface is a flat surface and the fine convex structure 3 is not formed. An adhesive is applied to the contact surface of the cover layer 1 and bonded to the underlay layer 2.
Being done.

  The cover layer 1 may be formed on one side of the underlay layer 2 or may be formed on both sides of the underlayer 2. In Examples 1 and 2, the cover layer 1 is formed by adhering only to the performance on one side of the underlay layer 2 and can display a pattern on one side. On the other hand, in the mount for the frottage technique of Example 3, the cover layer 1 is formed by adhesion on both sides of the underlay layer 2, and a pattern can be displayed on one side. In this case, the first cover layer 1, the underlay layer 2, and the second cover layer 1 are sequentially bonded and formed into a laminated structure with two adhesive layers 4 interposed therebetween. The double-sided frottage mount configured as in the third embodiment is formed into a booklet by binding a plurality of sheets prepared as substantially the same shape with a common side piece. Thus, the frottage technique can be drawn on both sides by turning the page.

(Fine convex structure 3)
A pattern of the fine convex structure 3 for drawing expression by the frottage technique is printed and formed on at least one of the contact surfaces of the cover layer 1 and the underlay layer 2. The pattern of the fine convex structure 3 is transferred to the surface of the cover layer 1, and the writing material is fixed on the transferred portion, whereby the pattern by the frottage technique is exposed. For this reason, the hardness of the fine convex structure 3 is larger than that of the cover layer 1.

  In Examples 1 and 3, the pattern of the fine convex structure 3 is formed only on the contact surface with the underlay layer 2 which is the back surface of the cover layer 1. In Example 2, the pattern of the fine convex structure 3 is formed only on the contact surface of the underlay layer 2 with the cover layer 1. As in Examples 1 and 3, a pattern of the fine convex structure 3 is printed on the contact surface of the underlayer 2 on the front and back cover layers 1 and the underlayer 2 is flat on both sides. The printing on the front surface and the fine convex structure 3 on the back surface do not shift at the time of bonding, and the double-sided frottage mount can be obtained as a single page without causing product loss.

  The pattern of the fine convex structure 3 is formed by screen printing, for example. The screen printing ink to be used is preferably a photopolymerization ink. As a suitable photopolymerization ink, there is a so-called UV ink which is cured by ultraviolet rays. This enables thick film printing with a relatively high coating thickness with a convex structure height of 3 h, and the fine convex structure 3 suitable for the frottage technique can be formed with the cured ink. Moreover, since it has a strong film and moderate elasticity, it is preferable as the fine convex structure 3 for pattern expression by the frottage technique. For example, 0 to 40% of a pigment, 30 to 90% of a photosensitive resin as a photopolymerizable low polymer (oligomer), 10 to 40% of a photosensitive monomer as a photopolymerizable monomer, and a photopolymerization initiator 3 as a sensitizer. What contains 10% of the component is used.

  Examples of the photopolymerizable low polymer include acrylates such as polyester acrylates, epoxy acrylates, urethane acrylates, polyol acrylates, methacrylates, and unsaturated polyesters. Of these, epoxy acrylates excellent in surface curability are preferably used.

  As the photopolymerizable monomer, either a monofunctional monomer or a polyfunctional monomer is used, and those having low viscosity, low skin irritation and odor, and excellent solubility and curability are preferable.

  As the photopolymerization initiator, any of benzophenone series, benzoin series, acetophenone series, and thioxanthone series is used. Those having excellent radical generation efficiency, low odor, toxicity and coloration and excellent storage stability are preferred. The pigment is preferably a clear type or a white type similar to the cover layer 1.

  The fine convex structure 3 bulges in the central part of the convex width direction from both ends (by a predetermined bulge amount) in order to improve the fixing property, shape stability, and the expression of the frottage pattern of the fine convex structure 3. It is preferable that the height of both end portions is larger than the thickness of the adhesive layer 4. In particular, the fine convex structure 3 preferably has a bulge amount at the central portion in the convex width direction that is at least half the height of both end portions.

  Further, in order to express the frottage pattern satisfactorily, the convex structure width 3w of the cross-sectional shape of one fine convex structure 3 is preferably about 10 to 40% larger than the convex structure height 3h. For example, the convex structure width 3w can be 60 to 100 μm, and the convex structure height 3h can be about 60 to 70 μm at the center and about 35 to 45 μm at both ends. Further, when the convex structure height 3h is larger than the thickness of the cover layer 1, the pattern expression of the frottage technique is clearly exposed. On the other hand, when the thickness is smaller than the thickness of the cover layer 1, the cover layer 1 is more durable without being broken during transportation or drawing.

(Adhesive layer 4)
The cover layer 1 and the underlay layer 2 are bonded and formed via an adhesive layer 4. The adhesive layer 4 is formed by being applied to at least a region between the flat contact surfaces where the pattern of the fine convex structure 3 is not formed, that is, a flat region excluding the pattern region of the fine convex structure 3.

  An adhesive layer 4 is uniformly applied and formed on the entire surface of one of the cover layer 1 and the underlay layer 2 (with substantially the same thickness), and the pattern of the fine convex structure 3 is formed on the adhesive layer 4. Further, the back surface of the cover sheet 1 is abutted and bonded to each other, whereby the layers are laminated. The thickness of the adhesive layer 4 is smaller than the fine convex structure height 3 h, and is preferably about 10 to 50 μm. In the first embodiment, the adhesive layer 4 is formed on the entire surface of the flat contact surface of the underlay layer 2 with a substantially equal thickness. In addition to the contact surface of the underlay layer 2, the adhesive layer 4 is applied to the entire contact surface (or a part of the flat surface) of the cover layer 1 on which the fine convex structure 3 is formed as in Example 2 described later. It is good also as what forms.

(Underlay layer 2)
The underlay layer 2 has a higher surface hardness than the cover layer 1 and plays the role of an underlay plate in the drawing of the frottage technique. Specifically, the cover layer 1 can be deformed relatively flexibly by the fine convex structure 3 while the underlayer 2 has a relatively strong surface hardness that does not cause the imprint by the fine convex structure 3. Have

  In the underlay layer 2 of Example 1, the entire contact surface with the cover layer 1 is a flat surface. That is, the pattern of the fine convex structure 3 is not printed on the contact surface, and can be drawn by the frottage technique only by the pattern of the fine convex structure 3 obtained by printing the back surface of the cover layer 1.

(Production method)
The mount for the frottage technique of the present invention is manufactured by sequentially performing the following steps. That is, (a) a printing 10 process in which a contour or frame-shaped printing 10 is applied to the surface of the cover layer 1, and (b) a fine convex on the contact surface of either the cover layer 1 or the underlayer 2 that has undergone the printing 10 process. A convex structure forming step for forming a pattern of the structure 3; and (c) an adhesive applying step for forming an adhesive layer 4 by applying an adhesive to the contact surface of either the underlayer 2 or the cover layer 1 or both. And (d) a bonding step in which the back surface of the cover layer 1 that has undergone the back surface printing step and the contact surface of the underlay layer 2 that has undergone the adhesive coating step are brought into contact with each other to bond the two layers. Moreover, it is preferable to pass through the cutting process which cuts the laminated board | substrate bonded together to the predetermined shape after the bonding process.

  If it is such, the shift | offset | difference with printing and the pattern of the fine convex structure 3 does not arise in a bonding process. In addition, since the adhesive is applied to the contact surface of the underlying layer 2 made of a flat surface, uniform adhesive application is possible and reliable bonding that is difficult to peel off can be performed.

  Among the above, (b) the convex structure forming step is a so-called back convex structure forming step in which a pattern of the fine convex structure 3 is formed by performing screen printing with ultraviolet curable ink on the back surface of the cover layer 1 that has undergone the printing 10 step. Preferably there is. Further, among the above, (c) the adhesive application step is a so-called both flat surface adhesive application step in which the adhesive is applied to both the underlay layer 2 and the cover layer 1 in the flat surface region of the contact surface. It is preferable.

  If it is such, the shift | offset | difference with printing and the pattern of the fine convex structure 3 does not arise in a bonding process. In addition, since the adhesive is applied to the contact surface of the underlying layer 2 made of a flat surface, uniform adhesive application is possible and reliable bonding that is difficult to peel off can be performed.

(Usage example)
The mount for the frottage technique of the present invention can be drawn by rubbing a writing material of an arbitrary color on the surface of the cover layer 1 like a painting to draw the pattern, and the frottage technique can be drawn. Moreover, since the underlay layer 2 is laminated and bonded in advance, there is no deviation from the outline of the three patterns of the fine convex structure, and a more authentic pattern can be surely expressed by drawing with a simple coloring method. The frame shape can be various outlines such as animal pictures as in the first and second embodiments (FIGS. 1 to 5), or can be a display frame as in the third embodiment (FIG. 6). The fine convex structure for expressing the pattern by the frottage technique is not limited to the one shown in Examples 1 and 2 (FIGS. 1 to 5), but the character as shown in Example 3 (FIG. 6). Information such as graphics, symbols, etc. can be expressed. In the present application, information expression such as characters that are not a painting technique as in the third embodiment is also based on the frottage technique.

  FIG. 4 shows an exploded view of the cover layer 1 and the underlay layer 2 and FIG. 5 shows a partial cross-sectional structure in a side view of the mount for the frottage technique of Example 2 of the present invention. In Example 2, as shown in FIGS. 4 and 5, the cover layer 1 in which the adhesive layer 4 is formed on the flat contact surface on the back surface with a substantially equal thickness, and the pattern of the fine convex structure 3 on the front contact surface. Is formed from the underlay layer 2 formed. Further, as shown in FIG. 5, the adhesive layer is applied to the entire contact surface of the underlying layer 2 provided with the fine convex structure 3 to form the lower adhesive layer 4. The lower adhesive layer 4 and the upper adhesive layer 4 formed on the cover layer 1 are self-adhering to each other, so that stronger adhesion is possible. Further, by providing the fine convex structure 3 on the underlayer 2 having a higher hardness than the cover layer 1, the fixing property of the fine convex structure 3 is improved. Other configurations not specifically mentioned are the same as those in the first embodiment.

  FIG. 6 shows a partial cross-sectional structure in a side view of the mount for the frottage technique according to the third embodiment of the present invention, and FIG. 7 shows an overview before and after the appearance of the frottage pattern by drawing. In Example 3, as shown in FIGS. 6 and 7, a mount for a frottage technique in which three layers of a first cover layer 1, an underlay layer 2, and a second cover layer 2 are bonded and formed is used as each page of a booklet. A plurality of sheets are prepared, and a common side of each sheet is formed in a booklet shape with a binding side.

  Each mount for the frottage technique that constitutes the inner paper of the booklet is composed of first and second contact surfaces on which both sides of the underlayer 2 are flat, and the first and second adhesive layers 4 are formed on each surface. The first and second cover layers 1 are brought into contact with and adhered to the first and second adhesive layers 4 to form a layer.

  As shown in FIG. 7, the character string of the question and the frame of the answer column are formed on the print 10, and the answer of the question is displayed as a pattern by filling the frame (the lower diagram in FIG. 7).

  By using the underlayer 2 of the flat contact surface on both ends as an intermediate layer as in this embodiment, each mount for the frottage technique does not deviate from the print and the frottage pattern, and can be securely bonded. it can. For this reason, the product loss by the shift | offset | difference of the adhesion | attachment position of the pattern underlay layer 2 does not generate | occur | produce. In particular, when it is formed in a booklet shape, if there is even one page misalignment between the print and the frottage pattern, it will lead to a missing page. However, the configuration of this embodiment can reduce the occurrence rate of missing pages. Further, since the adhesive layer is formed on the flat contact surface, it is easy to apply the adhesive evenly, and the thickness of each of the frottage mounts can be obtained more evenly. Thereby, even if a booklet is constituted by a plurality of mounts for the frottage technique, the thickness of the booklet can be made uniform. Other configurations not specifically mentioned are the same as those in the first embodiment.

  The present invention can be used as a so-called coloring board that draws a pattern by rubbing writing materials like a coloring book, and also displays hidden information such as characters and figures by rubbing the writing material. It can also be used as a so-called hidden character or hidden picture display mount to be recognized. Further, by increasing the thickness and hardness of the underlay layer 2, it is possible to make a thick single mount for drawing a picture, and for example, as shown in the third embodiment, a common one of a plurality of mounts is used. It is also possible to create a booklet by binding the sides to form a booklet and displaying the answer to the question. The present invention is not limited to the above-described embodiments including the specific configuration and usage of each part, and various modifications and combinations are possible without departing from the spirit of the present invention.
