Description

  The present invention relates to a drawing material, and more particularly, to a drawing material used in a place where water play is possible such as a bathroom.

Conventionally, various drawing materials have been proposed.
For example, a resin such as vinyl acetate or polyethylene is added to wax, fats and oils and pigments, or a metal soap added thereto, and heated to disperse the pigment in a melt of other materials. A creon characterized by being molded and cooled and solidified has been proposed (Japanese Patent Laid-Open No. 49-127728).

  In addition, a white board writing instrument is proposed (Japanese Patent Laid-Open No. 50-102427) characterized in that it contains at least several tens of percent or more of metal soap as a main component in a weight ratio, and a desired pigment is mixed therewith. ing.

  Also proposed is a writing instrument for white boards, characterized in that it contains at least several tens of percent or more of metal soap as a main component in a weight ratio, and a softening agent in which a desired pigment is dissolved is added thereto. 51-9930).

A marking pencil having a dye carrier kneaded and having a pencil material housed in a casing, the pencil material comprising at least one water-soluble metal soap, a monosaccharide, an oligosaccharide, and Proposed is a marking pencil comprising at least one of polyols derived from them as a structure-forming component, which forms a gel-like structure together with moisture in the pencil material (Japanese Patent Laid-open No. Hei 6-1994). 33010).
JP-A 49-127728 Japanese Patent Laid-Open No. 50-102427 Japanese Patent Laid-Open No. 51-9930 JP-A-6-33010

  By the way, Creon disclosed in JP-A-49-127728, for example, 140 parts by weight of paraffin, 160 parts by weight of hardened oil, 145 parts by weight of pigment, 55 parts by weight of vinyl acetate resin, 390 parts by weight of metal soap, 110 parts by weight of microwax is heated to 100 ° C to 120 ° C, the pigment is uniformly dispersed, solidified by cooling, and a round bar-like drawing material (Creon) is used to draw a picture on the floor of a bathroom, for example. When I tried to draw it and then wash it off with bath water, I couldn't wash it off easily.

  In Japanese Patent Laid-Open No. 49-127728, there is no idea that, after drawing at a place for water play, it is flushed with water and erased. Therefore, it is natural that there is no idea that the creon disclosed in Japanese Patent Application Laid-Open No. 49-127728 is used for drawing on the premise that it is erased in a place where water play is possible.

  Further, a white board writing instrument disclosed in JP-A No. 50-102427, for example, a white board writing instrument comprising 42 parts by weight of bitumen, 42 parts by weight of zinc stearate (metal soap) and 16 parts by weight of n-octyl alcohol. And white paper writing tools disclosed in JP-A-51-9930, for example, 80 parts by weight of zinc stearate (metal soap), 2 parts by weight of butyl carbitol, 15 parts by weight of oleic acid and 3 For example, if you draw a picture on the floor surface of a bathroom using a writing instrument for white board consisting of a heavy part of oil and blue, and then try to wash it off with bath water, you can easily wash it off. It was not.

  Incidentally, the writing instruments disclosed in Japanese Patent Laid-Open Nos. 50-102427 and 51-9930 are, as understood from the name of the invention called white board writing tools, originally drawn in a water play place and then watered. There is no idea that it will be washed away. Therefore, there is no idea that the writing instrument disclosed in Japanese Patent Application Laid-Open Nos. 50-102427 and 51-9930 is used for drawing on the premise that it is erased in a place where it can be played with water. And of course.

  Japanese Patent Application Laid-Open No. 6-33010 also has no idea that after drawing in a water play place, it is flushed with water and erased. That is, there is no idea that the marking pencil disclosed in Japanese Patent Application Laid-Open No. 6-33010 is used for drawing on the premise that the marking pencil is washed away in a place where water play is possible. Rather, the description in JP-A-6-33010, particularly the description in paragraph [0020] “To further improve the adhesion of the mark written with the marking pencil of the present invention and shorten the drying time” In addition, in a preferred embodiment of the present invention, the pencil material contains, as an additional structure-forming component, a fatty substance such as a fatty substance, wax, waxy substance, etc. The addition of such a fatty substance. By doing so, it is possible to reduce the time it takes to withstand wiping, especially when it is made on a surface that has no or very low absorbency. " It is not a marking pencil that assumes that.

  Therefore, the problem to be solved by the present invention is to provide a drawing tool that can be easily erased. Especially in places where you can play in the water, such as in a bathroom, you can draw letters and lines on the walls and floors, and after such work is done, for example, by flowing water etc. It is to provide a drawing tool that can be erased.

The above-described problem is a drawing material made of a solid material used in a place where water play can be performed,
The drawing material contains a soap component (however, metal soap is not included) , a saponifying agent, and a coloring material,
Solved by a drawing material , wherein the saponifying agent is 15 to 125 parts by mass and the coloring material is 0.03 to 9.4 parts by mass with respect to 100 parts by mass of the soap component. Is done.

  Further, the problem is solved by the above drawing material characterized by further containing a cleaning aid.

  Further, the problem is solved by the above drawing material characterized by further containing a surfactant.

  Furthermore, the problem is solved by the drawing material described above, which further contains a wetting agent.

  In the present invention, the soap component is preferably one or more selected from the group consisting of alkali metal salts of fatty acids that are readily soluble in water. And what is called a metal soap inferior to water solubility is not used. Particularly preferred soap components are compounds represented by RCOONa and RCOOK.

  In the present invention, the saponifying agent is preferably one or two selected from the group consisting of organic amines such as triethanolamine and diethanolamine, and alkali hydroxides such as M (an alkali metal such as M = Na and K) OH. More than a seed.

  In the present invention, the cleaning aid is preferably one or more selected from the group of solid fatty acids at 25 ° C. Examples thereof include saturated fatty acids such as lauric acid, stearic acid, myristic acid, and palmitic acid, and unsaturated fatty acids such as oleic acid and linoleic acid.

  In the present invention, the surfactant is preferably one or more selected from the group of an anionic surfactant and an amphoteric surfactant.

  In the present invention, the wetting agent is preferably one or more selected from the group consisting of monohydric alcohols, polyhydric alcohols, sugar alcohols, and sugars. Examples thereof include glycerin, diglycerin, propylene glycol, dipropylene glycol, ethanol, sorbitol, saccharose, glucose, and fructose.

  In the present invention, the preferred ratio of each component is as follows. That is, 15 to 125 parts by mass (more preferably 31 to 94 parts by mass) of a saponifying agent and 0.03 to 9.4 parts by mass of a coloring material such as a dye or pigment with respect to 100 parts by mass of the soap component. Part (more preferably, 0.09 to 6.3 parts by mass). When the cleaning aid is used, the cleaning aid is 9 to 63 parts by mass (more preferably 15 to 32 parts by mass) with respect to 100 parts by mass of the soap component. When the surfactant is used, the surfactant is 3 to 63 parts by mass (more preferably 9 to 32 parts by mass) with respect to 100 parts by mass of the soap component. When a wetting agent is used, the wetting agent is 18 to 125 parts by mass (more preferably 30 to 94 parts by mass) with respect to 100 parts by mass of the soap component.

  The drawing material of the present invention is used particularly in places where it is possible to play with water, such as in a bathroom. For example, characters and lines can be drawn on the walls and floors of a bathroom, and such work is finished. Later, for example, it is a drawing tool that can be easily erased by wiping with water or the like.

  At least a soap component, a saponifying agent, and a coloring material, and a picture drawn using the drawing tool of the present invention made of a solid body such as a stick is covered with water by the action of the included soap component. It can be easily washed off. Therefore, in places such as bathrooms, not only is it very useful for children's emotional education, but also easy to clean up later, so parents can play happily with their children, and skinship between children and parents Increased and favorable for home education.

  By the way, when metal soap is used instead of the soap component, the ease of cleaning up after the use of the soap component cannot be obtained. This ease of cleaning is one of the major features of the present invention. That is, it is a great feature of the present invention that both drawability and cleanability are excellent.

  Even if it is excellent in drawability, it is inferior in cleanliness, so it may be difficult to erase the child after graffiti, and it may result in ordering the child to ban graffiti and picking up the child's aggressiveness There is.

  Even if it is easy to clean up, if it is inferior in drawability, it will be inferior to emotional education and will not be used.

  In other words, having both of the above two features brings about great implications.

  The present invention is greatly characterized in that a soap component is used. However, there is a great feature not only in using soap components but also in using saponifiers. This is because only the soap component has insufficient detergency, so that a greater detergency is obtained by using a saponifying agent in combination. Thereby, it is excellent in workability when drawing is finished and erased. In addition, the drawing performance does not deteriorate.

  In the present invention, a cleaning aid (solidifying agent) such as saturated fatty acid or unsaturated fatty acid is preferably contained. By containing this cleaning aid (solidifying agent), the cleaning ability is further enhanced, and the drawing material has an appropriate hardness, and as a result, the drawing property is also improved.

  In the present invention, a surfactant is preferably contained. By including this surfactant, the cleaning ability is further enhanced.

  In the present invention, a wetting agent (clarifying agent) such as glycerin is preferably contained. By containing this wetting agent (clarifying agent), the drawing material has an appropriate hardness, and as a result, the drawing property is enhanced. In addition, the transparency is enhanced, and the decoration is good.

  And when said each component was mix | blended with the above-mentioned specific ratio, drawing property and cleansing property were much more excellent.
