A non-woven fabric, a felt-like fabric, or a fabric-like inorganic fiber can be used by cutting it into a size of, for example, 10 cm in length and 28 cm in width. The ground color layer 5 is an insect repellent non-display functional layer, but for example, as a white coloring agent, an organic substance such as amorphous silica, kaolin, calcium carbonate, or pulp powder can be applied. Vinyl acetate, EVA%NBR to fix on the four sides of the substrate material.
,SBR.

A binder such as acrylic or other latex is used, and the oil permeability of the ground color layer 5 can be appropriately set by appropriately selecting the mixing ratio of this binder.

Further, the base colored surface 7 is formed at the lower position of the base color layer 5 on the surface of the substrate material 4 by an oil-permeable base colored layer made of a colorant such as a pigment or dye and the above-mentioned binder. There is also.

Further, the sheet material 8 is used by forming a lower transparent column material such as a synthetic resin material such as polypropylene into a plate shape or a film shape.

In this embodiment, the ground color layer 5 is made transparent by the presence of the uniform mixed liquid 10, and the display function surface 6 of this insect repellent material 1 which also functions as an insect repellent indicator exhibits the ground color. When the insect repellent material 1 is used as an insect repellent indicator, the insect repellent liquid 11 is gradually volatilized and released from the display function surface 6. At this time, the auxiliary agent 12 promotes the movement of the insect repellent liquid 11 to the ground color layer 5 and further to the display functional surface 6, and further averages out the insect repellent liquid 11 over the entire area of the display functional surface 6. It acts like this. Next, after almost the entire amount of the insect repellent liquid 11 has been volatilized and released, the ground color layer 5 of the insect repellent material 1 that also functions as an insect repellent indicator becomes opaque, and the display function surface 6 exhibits the ground color on the surface of the ground color layer 5. become. At this time, the aid 12 is the insect repellent liquid 11
It acts to maintain the transparent state of the ground color layer 5 until just before it disappears.

In this manner, in this insect repellent material 1 that also functions as an insect repellent indicator, the display change regarding the insect repellent ability occurs in accordance with the time when the insect repellent effect disappears.

Next, as a second embodiment, an insect repellent material 1' which also serves as an insect repellent indicator and has an oil-impermeable pattern layer 13 on a main material 3 is shown in perspective views in FIGS. 2 and 3. A shown in longitudinal cross-sectional view. In this second embodiment, the pattern layer portion 13 is located below the ground color layer 5 and is partially coated on the 4 surface of the substrate material, and the other components are the same as those described above in the first embodiment. Same configuration as the example. The pattern layer 13 is formed by applying a coating method or various printing methods using an oil-impermeable forming material such as acrylic resin, synthetic resin such as polypropylene, or latex such as SBR.

In this second embodiment, the uniform mixed liquid 1° also reaches the ground color layer portion 5' forming the upper layer of the pattern layer 13, making the entire ground color layer 5 transparent, and serves as an insect repellent indicator. The display functional surface 6 of the insect repellent material 1' displays the pattern formed by the pattern layer portion 13 together with the base color. Further, after the insect repellent liquid 11 is volatilized from the display function surface 6 and almost the entire amount thereof is released, the ground color layer 5 becomes opaque and the display function surface 6 becomes opaque, as in the case of the first embodiment. The ground color on the surface of the ground color layer 5 will be exhibited, and at this time, the pattern created by the pattern layer 13 will also disappear significantly.

(Test Example 1) Paper material (length: 100m, width: 150 rtrm, thickness: 0
．． 5) is used as the substrate material 4, and amorphous silica is used as a coloring substance on the 4th surface of this substrate material, and a binder is applied 1:1 (by weight) to this.
A paper-like material 2 was prepared by adhering a main material 3 having a ground color layer 5 made of 35 g 4 (dry) of a coating liquid mixed at a ratio of 1.5 to 1.0 parts to a sheet material 8 made of polypropylene.

Next, a homogeneous mixed solution of 4-methyl-4-hebuten-1-yn-3-yl d-cis, trans-chrysanthemate and liquid paraffin 10 (liquid paraffin content; 16 (
(wt)%) was prepared.

This mixed liquid 10 was impregnated into the paper-like body 2 using an impregnation machine, so that 2.4 g of the mixed liquid 10 was contained in the paper-like body 2. In this case, the content of the insect repellent liquid agent 11 is 2.0
It was g. At this time, the display function surface 6 became transparent, and the insect repellent material took on a reddish hue, which is the base color of the insect repellent material.

Use this insect repellent material 1 that also serves as an insect repellent indicator from early spring to early summer (15~
28°C) and placed in a clothes drawer. As a result,
It was confirmed that the insect repellent liquid 11 was volatilized and disappeared at a rate of 10 kg per day, and it exhibited an effective insect repellent effect within a period of about 6 months, and its display function 6 It was confirmed that the whole sample was uniformly discolored to white.

(Test Example 2) Next, the paper-like material 2 in Test Example 1 was impregnated with 10 μl of various homogeneous mixed solutions obtained by mixing liquid paraffin as the auxiliary agent 12 in the proportions shown in Table 1 below. And so.

For each of these specimens, the insect repellent liquid agent 11 contained therein was completely volatilized and the color tone of the specimen was confirmed. Note that the blank was a paper-like material 2 that was not impregnated with anything.

Table 1〉 (x1) Proportion in the mixed liquid The results in Table 2 above show that when the proportion of the auxiliary agent 12 in the mixed liquid 10 is 20% (by weight) or less, the amount of the auxiliary agent 12 This shows that the background color layer 5 of the paper-like material 2 does not act to become transparent when only the color is used alone, and contributes to exhibiting an extremely remarkable display function.
