Abstract

PROBLEM TO BE SOLVED: To provide an aqueous paint composition excellent in flowability as a watercolor and capable of maintaining a shape drawn by fingers without generating paint remaining to be deposited to hands without being transferred to paper face when drawn by fingers.SOLUTION: An aqueous paint composition contains a pigment, a left rotary polarization gum arabic, montmorillonite clay mineral, a humectant, denatonium cation and water.EFFECT: A crystal of montmorillonite shows high dispersibility in water as denatonium cation is absorbed to a crystal terminal surface, forms a more three-dimensional associative structure due to status that space between crystal layers is swollen and difference of charges of crystal layer surface of montmorillonite and an edge surface, shows high shear viscosity reducing property, generates dramatic viscosity reduction by shear with rubbing between a coating surface such as paper surface and fingers and is coated and spread on a side range. Presence of the humectant wets montmorillonite and makes repeatedly forming the three-dimensional associative structure easy, and shear viscosity reducing property and viscosity recovery are conducted. Further the left rotary polarization gum arabic guarantees shear viscosity reducing property and viscosity recovery and adds cleanability capable of being removed by water.SELECTED DRAWING: Figure 1

Description

  The present invention relates to an aqueous paint composition to be painted with a finger.

  Conventionally, as a watercolor paint, those containing water, a pigment, and a thickener such as a cellulose-based polysaccharide or a water-soluble synthetic resin are generally known.

  In particular, the painting method of painting a paint on paper or the like with a finger or palm is called finger paint or finger paint, and is known as being able to express unique application different from the case of drawing with a paintbrush. .

  Patent Document 1 discloses a water-based paint composition that is comfortable to paint and exhibits a fluffy feel when applied by blending powdered cellulose having a specific fiber length as a watercolor paint premised on painting with a finger. Has been.

JP2015-89930A

  In paint compositions using cellulose or water-soluble synthetic resins, three-dimensional expression is possible due to the increase in viscosity, but there is a problem that wetting spread when painting with fingers is limited and coating efficiency is poor. there were.

  That is, as a result of adding a water-soluble synthetic resin or the like, the aqueous solution becomes sticky, and the fixability to the paper surface is preferable, but it also shows high adhesion to the fingers and is not transferred to the paper surface. This is probably because a considerable amount of paint that remains attached is generated.

  An object of the present invention is to provide an aqueous paint composition that is excellent in fluidity and can be widely spread even when drawn with a finger.

  The gist of the present invention is an aqueous paint composition containing at least a pigment, a montmorillonite clay mineral, a wetting agent, a denatonium cation, and water.

  The montmorillonite crystals are highly dispersible in water by adsorbing denatonium cations on the crystal end faces, and are attracted to each other due to the difference in the charge between the crystal layer faces and end faces of the montmorillonite. It is presumed that it forms a simple associative structure and exhibits high shear thinning, causing a sharp drop in viscosity due to shearing caused by rubbing between the coated surface such as paper and the finger and spreading over a wide range. Presumably, the presence of a wetting agent moistens the surroundings of montmorillonite and facilitates the formation of a three-dimensional association structure, thereby achieving shear thinning and viscosity recovery.

  In addition, when used in combination with levorotatory gum arabic, it adsorbs to the surface of the pigment and montmorillonite to assist the wetting effect, continuously guaranteeing viscosity reduction due to shearing and viscosity recovery when force is removed. In addition, it is presumed that cleaning properties that can be quickly removed with water are added.

  Gum arabic is a mixture containing a polysaccharide, an arabinogalactan protein in which the polysaccharide is bound to the protein backbone, and a protein. Gum arabic is attached to the surface of the pigment to impart dispersibility, and at the same time, is used to stably contain the pigment in the card house structure formed by the montmorillonite clay mineral. In particular, left-rotating gum arabic has a higher proportion of saccharides such as glucuronic acid that are easily soluble in water, and a lower proportion of saccharides such as galactose that is less soluble in water than right-rotating gum. Therefore, it is considered that levorotatory gum arabic is more soluble in water than right rotatory gum arabic, so when levorotatory gum arabic forms a film on the surface of an organic pigment, it is more soluble in water. As a result, detergency is improved. The amount of gum arabic used is preferably 0.1% by weight to 40% by weight with respect to the total amount of the aqueous paint composition.

The amount of the montmorillonite clay mineral used is preferably 0.8 to 2.0% by weight based on the total amount of the aqueous paint composition.

  Although the denatonium cation is known as an active ingredient of a bitter emetic, it is considered that in the present invention, it contributes to imparting shear thinning viscosity by dispersion of a montmorillonite clay mineral. The amount used is preferably 0.000001 to 5% by weight.

  As the wetting agent, in addition to wetting the surroundings of montmorillonite, a water-soluble high-boiling solvent is used as a wetting agent for slowing the drying rate of the aqueous paint composition after being applied to paper. Specific examples include glycerin, ethylene glycol, propylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol, diethylene glycol monomethyl ether, triethylene glycol monomethyl ether, and diethylene glycol dimethyl ether, which are preferably liquid at 20 ° C. In view of safety, it is preferable to use a wetting agent described in European standard EN71-7: 2014. If the amount used is too large, drying will be slow, and if it is too small, it will be dried during drawing and will not be able to exhibit sufficient fluidity, so 1 to 20% by weight with respect to the total amount of the aqueous paint composition. preferable.

  Other water-soluble resins can be used in combination for adjusting the viscosity and improving the fixability to paper. Specifically, water-soluble polymers such as locust bean gum, guar gum, tara gum, tragacanth gum, yellow dextrin, white dextrin, British gum, carboxyalkyl cellulose, hydroxyalkyl cellulose, polyvinyl alcohol, and water-soluble acrylic resin can be used. These can be used alone or in admixture of two or more.

If the amount of water-soluble resin used is small, sufficient fixability cannot be imparted. If the amount used is too large, the viscosity of the aqueous paint composition will increase, making it difficult to paint. Is preferably 1 to 30% by weight based on the total amount of the aqueous paint composition.

  An extender can also be added for the purpose of adjusting the viscosity to improve the ease of applying the paint or improving the color development of the color pigment on the paper surface. Specific examples of the extender include calcium carbonate, talc, mica, silica, kaolin clay, alumina silica, and barium sulfate. You may use individually or in mixture of 2 or more types. Also in view of safety, it is preferable to use a preservative described in European standard EN71-7: 2014. If the amount used is too small, the viscosity of the paint will be low and the three-dimensional effect cannot be expressed, and if it is too large, the viscosity of the paint will be high and it will be difficult to paint, so 0.1% of the total amount of the aqueous paint composition. % By weight to 40% by weight is preferred.

In addition, since no irregularities are formed on the drawing surface, a defoaming agent, an antifoaming agent, a surfactant, and the like can be used together as necessary.

  The method for producing the aqueous paint composition of the present invention is easily obtained by mixing and dispersing the components with a conventionally known stirring and dispersing machine such as a turbo mixer, a Henschel mixer, a three roll mill, a horizontal ball mill, or a horizontal bead mill. be able to.

  The aqueous paint composition thus obtained has a viscosity of 8,000 mPa · s or more at a shear rate of 1 / s and 4,000 mPa · s or less at 100 / S. By having such a viscosity characteristic, even when drawn with a finger, it is excellent in fluidity and can be spread widely.

  The viscosity at this time was measured with VISCOANALYSER VAR-100 (manufactured by Reologica, Sweden). The measurement conditions were a temperature of 25 ° C., using a φ20 parallel rotor, adjusting the gap with the mounting sample stage to 0.2 mm, and measuring viscosity at 20 logarithmically spaced from 1 Pa to 10,000 Pa in shear stress. The viscosity was measured at a shear rate of 1 / s and 100 / s.

  Containers that contain such aqueous paint compositions include polyethylene, polypropylene, polyethylene terephthalate, ethylene-vinyl alcohol copolymer, polyamide, polystyrene, polyacrylonitrile, polyethylene naphthalate, polyvinyl chloride, polyvinylidene chloride, and ethylene acetate. Single-layer or multi-layer blow-molded containers made of commonly used materials such as vinyl copolymer and aluminum, and pouch containers using single-layer or multi-layer films, etc., eject the paint composition by pushing the torso part of the container with your finger. It is suitable for making it. As shown in the perspective view of FIG. 1, when the discharge port 1 of the paint is not circular but has an irregular shape such as a star-shaped polygon, it is forced to be pushed out by the force of pushing the barrel 2 of the container. In addition, a shearing force is applied at the discharge port 1 to improve the discharge property due to a decrease in viscosity, and when there is a solid agglomerate such as a pigment due to collision, it has the effect of breaking and finely dispersing it. In single-layer or multilayer blow-molded containers using ethylene-vinyl alcohol copolymer or aluminum with high gas barrier properties, or pouch containers using single-layer or multilayer films, solvents such as water contained in the paint composition Can be prevented from evaporating through the container, and the performance of the paint composition can be maintained over a long period of time.
