JPH04251888A - Advertisement body using humidity measuring material - Google Patents

Abstract

PURPOSE:To provide an advertisement body whose pattern and color variation is enjoyable although the cost is low with respect to the advertisement body which is fixed on the roof of a building, etc., to attract observers' attention to the advertisements of company names and various enterprise images. CONSTITUTION:Basic dye and a water absorber are prepared in a weak acid methanol solution and an adhered member such as paper and cloth is dipped in the solution and dried at specific temperature to form the humidity measuring material 3 which changes in color with humidity. This humidity measuring material 3 is used at least part of the advertisement body 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is designed to be fixed to the roof of a building, the wall of a temporary enclosure at a construction site, the side of a scaffold, etc.
This relates to advertising materials that promote company names and various corporate images to viewers. [0002] Conventionally, advertising bodies such as billboards fixed on the rooftops of buildings have used various means to display the company name and corporate image on the media, such as coating paint or using neon tubes. They appealed by changing it with a rotating body. [Problem to be Solved by the Invention] However, in the above-mentioned public notice method, if the media is coated with paint by brush or printed, the initial pattern and color will gradually become boring without any change. There was also the problem of storage, and those using neon tubes or rotating bodies had changing patterns and colors that appealed to the viewer, but had the disadvantage of being expensive. The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide an advertising body that is low in cost and allows for enjoyable changes in patterns and colors. Means for Solving the Problems The gist of the present invention to solve the above problems and achieve the above objects is that after preparing a basic dye and a water absorbing agent in a weakly acidic methanol solution, The present invention consists in using a humidity measuring material, which is obtained by dipping an adherend material such as paper or cloth in water and drying the adherend material at a predetermined temperature, and which changes color due to changes in humidity, for at least a portion of the advertising body. [Function] The moisture measuring material absorbs water into the water absorbing agent of the humidity measuring material depending on the humidity around the advertising body, and its pH changes. The basic dye causes an ionic reaction and changes color in six stages: orange, ocher, light green, green, dark green, and purple. Therefore, the pattern and color of part or all of the advertising body in which the humidity measuring material is used changes in response to changes in humidity. Embodiments Next, the present invention will be explained with reference to the drawings. FIG. 1 is a front view showing how an advertising body 1 according to the present invention is used for an external scaffolding 2 of a building, etc., and FIG. 2 is a structure of a humidity measuring material 3 used in at least a part of the advertising body 1. FIG. As shown in FIG. 2, the humidity measuring material 3 is a medium 4 (for example, an iron plate or a plastic flat plate).
The surface is covered with a cover 5 made of a water-permeable material. The structure of the humidity measuring material 3 is that after preparing a basic dye and a water-absorbing agent in a weakly acidic methanol solution, a member to be adhered such as paper or cloth is immersed in the solution and heated to a predetermined temperature. The basic dye is crystal violet, the water absorbing agent is zinc bromide, zinc chloride, etc., the weak acid is oxalic acid, citric acid, etc., and the predetermined temperature is Celsius. It is about 70 degrees to 80 degrees. For details regarding the humidity measuring material 3, such as the reversible relationship between humidity and discoloration, please refer to the patent application filed in 1983 by the applicant.
-29680 and Japanese Patent Application No. 59-43531. As described above, since the humidity measuring material 3 is used in at least a portion of the advertising body 1, moisture is absorbed by the moisture absorbing agent of the humidity measuring material 3 through the cover 5 due to the humidity around the advertising body 1. As a result, the basic dye, which is a coloring indicator, undergoes an ionic reaction and changes color in six stages: orange, ocher, pale green, green, black-green, and purple. Therefore, the color of the humidity measuring material 3 that forms the picture or pattern of the advertising body 1 changes, increasing its appeal to viewers. [Effects of the Invention] As explained above, an advertising material using the humidity measuring material of the present invention can be obtained by preparing a basic dye and a water absorbing agent in a weakly acidic methanol solution, and then adding paper or other materials to the solution. By using a humidity measuring material, which is obtained by soaking an adherend material such as cloth and drying the adherend material at a predetermined temperature and which changes color due to changes in humidity, in at least a part of the advertising body, the cost of the advertising body is low. Moreover, it is a highly appealing advertising body with a rich variety of patterns and colors.
