Description

[Detailed description of the invention] The present invention relates to a design laminate.

More specifically, the present invention is constructed by laminating a substantially transparent base layer, two surface layers, and two adhesive layers that adhere the two surface layers to both surfaces of the base layer, and the surface of at least one of the surface layers is laminated. The present invention relates to a design laminate that has been treated to be writable or copyable, and in which both adhesive layers can be peeled off at the adhesive surface with the base layer. The design laminate according to the present invention includes, for example,
Draw designs such as letters and figures directly on the writable surface,
Cut the necessary parts, apply the desired water-based paint to the transparent base layer exposed by the cut, and remove the remaining surface layer to expose the transparent base layer to create a suitable colored design manuscript. It is something that can be done.

Conventionally, to create this type of manuscript, the manuscript creator would either glue a transparent synthetic resin film and a tracing film together using an adhesive, or glue sticky Mino paper to the synthetic resin film. Was.

Therefore, as long as conventional design laminates have been used, it has been necessary to use a regular design with the right and left sides reversed when writing the ring of the design. The main purpose of the present invention is to provide a design laminate that solves this problem.

Another object of the present invention is to provide a design laminate that can be easily changed when substantially the same pattern is continuously created with slight changes, such as when creating a moving image.

Another object of the present invention is to provide a design laminate that saves the time and effort required to make manuscript boards by hand, and which can be mass-produced at a very low cost.

One of the main structural features of the design laminate according to the present invention is that the surface layer is removably adhered to both sides of the base layer, and another structural feature is that at least one surface of the surface layer The purpose is to make it possible to write or copy. Due to these features, it is possible to easily create a design manuscript without creating in advance a design in which the right and left sides of the regular design are reversed. In other words, by first drawing or copying the original original drawing on one surface and then copying it onto the other surface, it is possible to obtain an image with the right and left sides reversed, and based on that reverse drawing, the original design can be created. There is something for creating a manuscript. The design laminate according to the present invention is preferably made transparent or semi-transparent (transparency of about 50% or more) as a whole.

In many cases, a sketch is drawn on one surface of the surface layer either directly by placing the original painting underneath it or by shining light onto the original painting and transferring it, and then that sketch is drawn either directly from the surface of the other surface layer or by shining light onto the sketch and shining through it. Because you need to see it. The thickness of the plate is approximately 35 to 300 microns, which is easy to handle when creating a design manuscript and can be mass-produced at low cost.
In the present invention, the surface of the surface layer is treated to be writable or copyable, which means that the surface of the surface layer is treated to be easily written on with a pencil, ballpoint pen, brush, etc., and for example, a rough surface so that a sketch of an original drawing (design) can be line-drawn. For example, it means that a composition containing a photosensitive material has been subjected to a surface treatment so that it can be copied using a copying machine or the like.

Specific examples of the above-mentioned surface roughening treatment include a method of roughening the surface layer surface by sandblasting, or a method of uniformly dispersing fine powder of about 2 to 1 ω microns of inorganic silica, talc, etc. on the surface. There is a method of roughening the surface layer by forming a synthetic resin film in a continuous manner.

On the other hand, specific examples of surface treatment using compositions containing photosensitive materials include:

ns, Tnc. Published in 1965 66 Light-Ser
Examples include those using the photosensitive materials described in Chapter 1 and Chapters 3 to 9 of lsitiveSysStems.

Preferably, a composition based on a diazo compound for dry development described in Chapter 6 is used. In the present invention, the surface layer is preferably water-resistant because the coloring material commonly used for design is water-based paint.

Examples of the material for this surface layer include oriented polypropylene, polyethylene terephthalate, polybutylene terephthalate, polyethylene phthalate, cellulose butyrate, cellulose diacetate, cellulose triacetate, and hard polyvinyl chloride. Most preferred is polyethylene terephthalate. The thickness of the surface layer is about 9-100 microns, preferably about 12-60 microns. In the present invention, the substantially transparent base layer is
In particular, it has a degree of transparency that does not cause any inconvenience when photographing the design, and has the appropriate strength as a substrate for the design.It also has good adhesion to commonly used water-based paints, and is also water resistant. It is necessary to be prepared.

Materials suitable for this purpose are oriented polypropylene,
Examples include synthetic resin materials such as polyethylene terephthalate and cellulose triacetate, and inorganic materials such as glass and ceramics. The thickness of the base layer is preferably thicker than the surface layer, and a suitable value is about 25 to 180 microns. However, it may be slightly thicker than these values. In the present invention, the adhesive layer that adheres both layers means a layer that substantially adheres the surface layer and the base layer, and specifically takes into consideration the provision of releasability on the adhesive surface and the ease of manufacturing, which will be described later. Preferably, a thin layer of pressure sensitive adhesive is used.

The thickness of this adhesive layer is preferably about 1 to 20 microns, and the material is a material such as natural rubber, synthetic rubber, polyacrylic acid, silicone resin, etc. that has pressure-sensitive adhesive properties at room temperature and is substantially transparent. Examples include pressure sensitive adhesives containing resin. In the present invention, the adhesive layer is designed to be peeled off at the adhesive surface with the base layer, which means that when an attempt is made to peel the surface layer and the base layer, the adhesive layer that adheres both layers must separate from the base layer, that is, the adhesive layer This means that it is separated while being adhered to the surface layer.

In other words, the bond between the adhesive layer and the base layer must be a releasable adhesive, and the bond between the adhesive layer and the surface layer must have a higher adhesive strength than the releasable adhesive. Therefore, for such purposes, if the material of the adhesive layer cannot achieve the above-mentioned difference in adhesion to the surface layer and base layer, the back surface of the surface layer should be roughened by sandblasting or solvent etching, or by corona discharge treatment. oxidized, treated or under-treated to increase adhesion.
Coating is required. Preferred undercoatings include mixtures of linear polyester and polyurethane compounds. Of course, if the material of the adhesive layer itself allows the above-mentioned adhesion conditions to be applied to the surface layer and the base layer, it is not necessary to perform the above-mentioned treatment on the back surface of the surface layer.

The present invention will be described in detail below based on embodiments shown in the figures.

Note that the present invention is not limited thereby. In Figs. 1 to 7, reference numeral 1 denotes a design synthetic resin laminate with a thickness of about 105 microns, which in order from the top includes an upper surface layer 2, a first adhesive layer 3, a base layer 4, a second adhesive layer 3'', and a lower surface layer 2''. It is constructed by laminating layers.

The upper surface layer 2 is made of biaxially oriented polypropylene.
Fine powders such as silica and talc are dispersed in a synthetic resin coating and applied to the upper surface of the layer with a thickness of about 0 microns to form a roughened film of about 4 microns to improve writability and water resistance. The lower surface is then subjected to corona discharge treatment. Note that the contact angle with respect to water in this corona discharge treatment was set to 78 water or less. The first adhesive layer 3 is a transparent pressure-sensitive adhesive with a thickness of about 6 microns made of a nitrocellulose/acrylic acid polymer and a polyurethane initial condensate having active isocyanate groups, and is made of a smooth flat surface of biaxially oriented polypropylene. It has peelability and is easy to break.

) The base layer 4 is a smooth transparent layer of about 75 microns of biaxially oriented polypropylene and is water resistant.

Therefore, the first adhesive layer 3 can be peeled off at the lower adhesive surface which is the adhesive surface with the base layer 4 among its upper and lower adhesive surfaces.
The second adhesive layer 3'' and the lower surface layer 2'' are the first adhesive layer 3.
The same layer as the upper surface layer 2 is laminated symmetrically with respect to the base layer 4, and the explanation thereof will be omitted.

Next, a method for creating a design manuscript using the design synthetic resin laminate 1 described above will be described. First, an original drawing (regular sketch) is drawn directly with a pencil on the surface 5 of the upper surface layer 2 of the synthetic resin laminate 1 for design (FIG. 1).

Next, turn the laminate 1 upside down and place the print line 6 on the lower surface layer 2.
6'' is made so that it is visible from the surface 5'' of the surface layer 2'', and the image 6'' is copied onto the surface 5'' of the lower surface layer 2'' (Fig. 2).Subsequently, the image 6 is applied to the upper surface. The surface layer 2 is removed from the base layer 4 in the direction of arrow A. Since the first adhesive layer 3 is provided so that it can be peeled off at the adhesive surface with the base layer 4, the first adhesive layer is removed from the base layer 4 together with the upper surface layer 2. It peels off (Figures 3 and 4). Then, the lower surface layer 2'' is cut with a knife along the drawing line 6'', and the cut part of the lower surface layer 2'' is pulled up in the direction of arrow B (Figure 5). ).

Here, as explained above, the peeling surface is the second adhesive layer 3''.
The cut lower surface layer 2''
and the corresponding second adhesive layer 3'' are peeled off.Next, a predetermined color 7 is applied from above by spraying, and the remaining lower surface layer 2'' is pulled up in the same way and peeled off. Figure 6). When applying the color, the adhesion of the color is good because no part of the second adhesive layer 3'' remains on the base layer 4.Of course, the second adhesive layer 3'' is also peeled off and cut. Only the color 7 corresponding to the drawn shape remains on the base layer 4, and a colored original with correct right-left positional relationship is completed. In other words, a colored design manuscript with a correct image when viewed from the direction of arrow D is completed (FIG. 7).
It would be better if the creation of the drawing line 6'' in Fig. 2 could be omitted; in this case, the drawing line 6'' was created directly with a knife.
A cut corresponding to `` is attached.

Further, the completed colored original may be superimposed on other colored originals to form a multicolor printing original, or may be superimposed on a ready-made background original. In FIG. 6, before peeling off the entire remaining lower surface layer 2'' together with the second adhesive layer 3'', a part of the lower surface layer 2'' is further cut, that part is peeled off, and a different color is applied. By peeling off the remaining lower surface layer 2'' together with the second adhesive layer 3'', a two-color printing original is completed.

Note that when creating the design manuscript, since the structure of the laminate 1 is vertically symmetrical with respect to the base layer 4, its front and back may be reversed.

In the above embodiment, a method for creating a design manuscript without any changes to the original design was explained. However, when making changes, for example, the correct drawing line 6 on the right and left in FIG.
The drawing line 6'' that reverses the right and left sides of the surface 5 of the lower surface layer 2''
Instead of creating a drawing line 6'' on the same surface, you can make a change and create a drawing line 6'' on the same surface.

Also, unlike the above embodiments, the surfaces of the upper and lower layers may be treated to make them copyable. Further, one may be processed to be writable and the other to be copyable, or both may be used in combination. Furthermore, it is also possible to apply coloring to both sides of the base layer as a special colored original.

Other combinations of materials that have the same structure as the synthetic resin laminate 1 shown in FIG. 1 are illustrated below.
