To improve the toy characteristics.
The diaper 3 has a base 31 made of a woven fabric, a nonwoven fabric, a knitted fabric or a synthetic paper, and has a low refraction on the outer surface of the diaper 3 located in the vicinity of the water or simulated beverage excretion. A porous layer 33 is provided which is fixed in a dispersed state to a binder resin and is opaque in a non-water absorption state and transparent in a water absorption state.
Note that the diaper 3 is not limited to the one directly attached to the doll body, but adjusts the amount of excretion by interposing a cotton-like or other water absorbing material and allows moisture to permeate the porous layer 33. An adjusted configuration may be used.

  Examples of the low refractive index pigment include fine-particle silicic acid, barite powder, precipitated barium sulfate, barium carbonate, precipitated carbonic acid having a refractive index of 1.4 to 1.7 and a particle diameter of 0.03 to 10 μm. Calcium, gypsum, clay, talc, alumina white, basic magnesium carbonate, etc. are mentioned. Among them, particulate silicic acid is effective in terms of concealability, transparency, workability, etc., and two or more types may be used in combination. it can.

As a low refractive index pigment suitably used, fine particle silicic acid can be mentioned.
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 with an acid such as sodium silicate (hereinafter referred to as wet method fine particle silicic acid), and any of them can be used. When the wet method fine particle silicic acid is used, since the concealability in the normal state is larger than that of the dry method fine particle silicic acid system, it becomes possible to increase the compounding ratio of the binder resin to the fine particle silicic acid. Since the film strength of itself can be improved, it is used more suitably.
The wet method fine particle silicic acid has a so-called two-dimensional structure part in which silicic acid is condensed to form a long molecular arrangement, and the molecular structure is coarser than that of a three-dimensional dry method fine particle silicic acid. Therefore, the system to which the wet method fine particle silicic acid is applied is superior in the diffused reflection of light in the dry state as compared with the dry method fine particle silicic acid system, and has a large concealment property in the normal state. The fine particulate silicic acid has the most hydroxyl groups present as silanol groups on the particle surface as compared with the dry fine particulate silicic acid. Therefore, it has an appropriate hydrophilicity and has a large water absorption effect, and is most preferable.

When the wet method fine particle silicic acid is used as a low refractive index pigment, it depends on the properties of the wet method fine particle silicic acid, the particle diameter, the specific surface area, the oil absorption amount, etc. to satisfy transparency together is preferably applied amount is ^{0.01g / 100cm 2 ~0.30g / 100cm 2} , more ^{preferably, 0.05g / 100cm 2 ~0.2g / 100cm} 2 It is. If it is less than 0.01 g / 100 cm ² , sufficient concealability cannot be obtained in a normal state. On the other hand, if it exceeds 0.3 g / 100 cm ² , sufficient transparency cannot be obtained during liquid absorption.
The low refractive index pigment is dispersed in a vehicle containing a binder resin to form a dispersed ink, and the porous layer 33 is formed on the desired location of the diaper substrate 31 by printing, coating, spraying, or the like.

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, epoxy resin and the like can be mentioned.
Among them, it is effective to use a urethane resin or to contain at least a urethane resin.
By containing the urethane resin in the binder resin, the film strength of the porous layer 33 can be improved, and the concealability in the dry state and the transparency in the liquid absorption state are not impaired.

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 that is self-emulsified without the need for an emulsifier due to the ionic groups of the ionic urethane resin (urethane ionomer) itself, and is dissolved and 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, particularly a urethane-based emulsion resin or a colloidally dispersed urethane-based resin is preferable. Used for.
The urethane resin is preferably used alone, but other binder resins can be used in combination depending on the required film strength. When a binder resin other than the urethane resin is used in combination, in order to obtain a practical film strength, the urethane resin is preferably contained in the binder resin of the porous layer 33 in a solid content ratio of 30% by weight or more. .
In the porous layer 33 formed as described above, conventionally known titanium dioxide-coated mica, iron oxide-titanium dioxide-coated mica, iron oxide-coated mica, guanine, sericite, basic lead carbonate, acidic arsenic acid Metallic pigments such as lead and bismuth oxychloride can be added, or general dyes and pigments, fluorescent dyes and pigments can be added to diversify the color change. Furthermore, a reversible thermochromic material that changes color reversibly with temperature can be blended.

The water-repellent resin layer 34 has a water-repellent treatment liquid containing a water-repellent resin containing a water-repellent resin selected from silicon-based, paraffin-based, polyethylene-based, alkylethyleneurea-based, and fluorine-based water-repellent resins in an appropriate shape on the porous layer 33. It is a layer that exists in and coexists with the porous layer 33 obtained by adhering to form an image and osmotic drying.
Among the water-repellent resin, fluorine-based water repellent is effective in terms of water repellency and processing suitability, as ^{solid, 0.01g / 100cm 2 ~0.50g / 100cm} 2, preferably, deposition amount in the range of 0.02g ^/ 100cm ² ~0.30g ^/ 100cm 2 is valid.

  The colored layer 32 is a layer that is directly formed on the outer surface of the diaper base 31, and the porous layer 33 is seen through in a water-absorbing state, thereby changing the appearance and enhancing toy properties. It is not limited to those formed by a color material containing a coloring agent such as a dye or a pigment, but may be a reversible thermochromic material formed by a color material containing a reversible thermochromic material. The substrate 31 may be colored (already colored) in the fabric and paper systems.

The porous layer 33, the water-repellent resin layer 34, and the colored layer 32 described above are not limited to those printed in a solid form, but those formed with images of characters, symbols, alphanumeric characters, lines, figures, designs, etc. are effective. It is.

  Examples are shown below. In addition, the part in an Example shows a weight part.

Example 1 (see FIGS. 2 to 4)
Using a pink screen printing ink, the entire surface of the broad substrate 31 made of a white polyester / cotton blend (mixing ratio 65:35) is solid-printed on a 150 mesh screen plate at 100 ° C. Was dried and cured for 5 minutes to form a pink colored layer 32.
Next, 15 parts of wet process fine powder silica, 45 parts of urethane emulsion (solid content 30% by weight), 40 parts of water, 0.5 part of a silicone-based antifoaming agent, and thickening for water-based ink are formed on the entire surface of the colored layer 32. Using a white screen printing ink with 3 parts of an agent, 1 part of ethylene glycol, and 3 parts of a crosslinking agent mixed and stirred uniformly, solid printing is performed on a 100-mesh screen plate and dried and cured at 130 ° C. for 5 minutes. Thus, the porous layer 33 was formed.
Next, 50 parts of fluororesin water repellent [trade name: NK guard NDN-7E, manufactured by Nikka Chemical Co., Ltd., solid content 22 wt%] on the porous layer 33, 1.5 parts of sodium alginate, water 48.5 parts, 0.5 part of silicone-based antifoaming agent, 5 parts of cross-linking agent are mixed and stirred uniformly. Using a colorless and transparent screen printing ink, a star pattern is drawn on a 100 mesh screen plate. It was printed and dried and cured at 170 ° C. for 2 minutes to form a water-repellent resin layer 34 (star pattern) in the porous layer 33 to obtain a water-discoloring fabric.
In the water discolorable fabric, the porous layer 33 is white in the normal state (non-water-absorbing state), and the water-repellent resin layer 34 itself is colorless and transparent, so that the entire surface is in a white state and the star pattern is in a latent image state. is there.
The water discolorable fabric was sewn into a doll diaper to form a water discolorable diaper 3, and the milk drinking doll was mounted so that the surface on which the colored layer 32 and the porous layer 33 were printed was on the outside. .
In the normal state (non-water-absorbing state), the water discolorable diaper 3 was visually recognized as a white diaper and the pink colored layer 32 was hidden and invisible, As a result of the release of water, the outer porous layer 33 becomes water-absorbed and the porous layer 33 becomes transparent, and a pink color is visible, but the water-repellent resin layer is present in the porous layer 33. In the portion where 34 is formed in an inherent state, the water-repellent resin layer 34 prevents water from being absorbed, and the transparent porous layer 33 (star pattern) in the water-absorbing state is made transparent so that the pink star pattern and the white pattern The back was visible.
In the state where the water was attached, the pink star pattern and the white background were exhibited, but when the water evaporated, the entire surface became white and the star pattern returned to the latent image state.
The change in appearance could be repeatedly reproduced by the same operation.
