  The present invention solves the above-mentioned problems. That is, since a child can freely form various images without using a place of use, and can be used in a correct posture, long-time play has been satisfied. A water-coloring toy and a water-coloring toy set using the same are intended to be provided.

The present invention comprises, on at least a part of a toy surface, a porous layer having different transparency in a liquid absorption state and a non-liquid absorption state in which a low refractive index pigment is fixed to a binder resin in a dispersed state, A water-coloring toy in which the length in the vertical direction, the length in the horizontal direction, and the length in the height direction are all in the range of 10 to 100 cm is a requirement.
Furthermore, the maximum value and the minimum value satisfy the following formula (1) among the length in the vertical direction, the length in the horizontal direction, and the length in the height direction.
1 ≦ maximum value / minimum value ≦ 3 (1)
The area occupied by the porous layer in the total surface area is 10 to 100%, the shape is spherical or polyhedral, the support on which the porous layer is provided is a fabric, and the fabric is used as a stuffed skin It is a requirement that
Furthermore, a water color changing toy set comprising the water color changing toy and water adhering means is required.
Furthermore, the water adhering means is selected from any of a writing instrument or applicator applied with a plastic porous body or fiber processed body having continuous pores as a nib member, or a stamp tool. It is required to be configured to be capable of being accommodated, and to be provided with a container for water adhering means that is integral with or separate from the toy on the toy surface.

The present invention is capable of forming various images freely for infants and the like without restriction on the place of use, and can form images with the correct posture when used, so it is highly practical and convenient for long play. A water-coloring toy can be provided.
In addition, by setting the water color changing toy and the water adhering means as a set, it is possible to provide a highly practical water color changing toy set that makes an image appear easily.

The porous layer formed on the toy is a layer in which a low refractive index pigment is fixed in a dispersed state together with a binder resin.
Examples of the low refractive index pigment include fine particle silicic acid, barite powder, precipitated barium sulfate, barium carbonate, precipitated calcium carbonate, gypsum, clay, talc, alumina white, basic magnesium carbonate, and the like. Is in the range of 1.4 to 1.7 and exhibits good transparency when the liquid composition is absorbed.
The particle size of the low refractive index pigment is not particularly limited, but 0.03 to 10.0 μm is preferably used.
Two or more of the low refractive index pigments can be used in combination.
In addition, a particulate silica is mentioned as a low refractive index pigment used suitably.
The fine particle silicic acid may be obtained by a dry method, but fine particle silicic acid produced by a wet method (hereinafter referred to as wet method fine particle silicic acid) is particularly effective and satisfies practicality.
This point will be described below.
Particulate silicic acid is produced as amorphous amorphous silicic acid, and is produced by a dry process using a gas phase reaction such as thermal decomposition of silicon halide such as silicon tetrachloride (hereinafter referred to as dry process particulate silicic acid). And by a wet method using a liquid phase reaction such as decomposition by an acid such as sodium silicate, in order to function as a porous layer intended by the present invention, fine particles by a wet method are used. Silicic acid is optimal.
This is because the dry process fine particle silicic acid and the wet process fine particle silicic acid have different structures, and the dry process fine particle silicic acid forms a three-dimensional structure in which the silicic acid is closely bound, whereas the wet process fine particle silicic acid is It has a so-called two-dimensional structure portion in which silicic acid is condensed to form a long molecular arrangement.
Accordingly, since the molecular structure is coarser than that of the above-mentioned dry method fine particle silicic acid, when wet method fine particle silicic acid is applied to the porous layer, the light in the dry state compared to the system using the dry method fine particle silicic acid. Therefore, it is presumed that the concealability in the normal state is increased.
Further, since the porous layer of the present invention absorbs water, the wet method fine particle silicic acid has more hydroxyl groups present as silanol groups on the particle surface than the dry method fine particle silicic acid, and is hydrophilic. The degree of is large and is preferably used.
In addition, in order to adjust the concealability in the normal state of the porous layer and the transparency in the liquid absorption state, other general-purpose low refractive index pigments can be used in combination with the wet method fine particle silicic acid.

The wet method fine particle silicic acid in the porous layer depends on properties such as particle diameter, specific surface area, oil absorption, etc., but in order to satisfy both the concealing property in the normal state and the transparency in the liquid absorbing state. it is preferable that the coating amount is ^{1g / m 2 ~30g / m 2} , more preferably ^{5g / m 2 ~20g / m 2} . If it is less than 1 g / m ² , it is difficult to obtain sufficient concealability in a normal state, and if it exceeds 30 g / m ² , it is difficult to obtain sufficient transparency upon liquid absorption.
The particle size of the particulate silicic acid is not particularly limited, but 0.03 to 10.0 μm is preferably used.
The particulate silicic acid is dispersed in a vehicle containing a binder resin as a binder, applied to a substrate, and then dried of volatile matter to form a porous layer.
Examples of the binder resin include urethane resin, nylon resin, vinyl acetate resin, acrylic ester resin, acrylic ester copolymer resin, acrylic polyol resin, vinyl chloride-vinyl acetate copolymer resin, maleic resin, polyester resin, styrene. Resin, styrene copolymer resin, polyethylene resin, polycarbonate resin, epoxy resin, styrene-butadiene copolymer resin, acrylonitrile-butadiene copolymer resin, methyl methacrylate-butadiene copolymer resin, butadiene resin, chloroprene resin, melamine resin, and the above Each resin emulsion, casein, starch, cellulose derivative, polyvinyl alcohol, urea resin, phenol resin and the like can be mentioned.
The mixing ratio of the particulate silicic acid and these binder resins depends on the kind and properties of the particulate silicic acid, but preferably 0.5 to 2 parts by weight of the binder resin solid content with respect to 1 part by weight of the particulate silicic acid. More preferably, it is 0.8 to 1.5 parts by weight. When the binder resin solid content is less than 0.5 parts by weight with respect to 1 part by weight of the particulate silicic acid, it is difficult to obtain a practical film strength of the porous layer. Will deteriorate the water permeability into the porous layer.
Since the porous layer has a small mixing ratio of the binder resin to the colorant as compared with a conventionally known general coating film, it is difficult to obtain sufficient film strength. Therefore, in order to increase the scratch resistance, it is effective to use a nylon resin or a urethane resin among the binder resins.
Examples of the urethane resin include a polyester urethane resin, a polycarbonate urethane resin, and a polyether urethane resin, and two or more of them can be used in combination. In addition, a urethane emulsion resin in which the resin is emulsified and dispersed in water, or a colloid in which the resin is self-emulsified without the need for an emulsifier by an ionic group of the ionic urethane resin (urethane ionomer) itself and dissolved or dispersed in water. A dispersion type (ionomer type) urethane resin can also be used.
The urethane-based resin may be either an aqueous urethane-based resin or an oil-based urethane-based resin, but in the present invention, an aqueous urethane-based resin, in particular, a urethane-based emulsion resin or a colloidally dispersed urethane-based resin is suitable. Used for.
The urethane resin can be used alone, but other binder resins can be used in combination depending on the type of support and the performance required for the coating. When a binder resin other than the urethane resin is used in combination, in order to obtain a practical film strength, it is preferable to contain 30% or more of the urethane resin in a solid content weight ratio in the binder resin of the porous layer.
In the binder resin, the crosslinkable resin can be further improved in film strength by adding an arbitrary crosslinking agent and crosslinking.
The binder resin has a large or small affinity with water. By combining these, the penetration time into the porous layer, the degree of penetration, and the slow speed of drying after the penetration can be adjusted. Furthermore, the said adjustment can be controlled by adding a dispersing agent suitably.

In the porous layer, conventionally known titanium dioxide-coated mica, iron oxide-titanium dioxide-coated mica, iron oxide-coated mica, guanine, sericite, basic lead carbonate, acidic lead arsenate, bismuth oxychloride, etc. The color change can be diversified by adding a metallic luster pigment or mixing general dyes and pigments, fluorescent dyes and fluorescent pigments.
In addition, conventionally known reversible thermochromic pigments that reversibly change color according to temperature change can be mixed, and the color can be changed depending on the environmental temperature or the water temperature to be adhered.
Furthermore, the color change can be further diversified by providing a colored layer in the upper layer, the lower layer, and / or the vicinity of the porous layer.
