Definitions

  • This invention relates to a drawing toy in which images such as letters or characters and patterns or designs having brilliance can be formed by applying water thereto, and a drawing toy set making use of the same.
  • a water image sheet having a support and provided thereon a porous layer in which a low refractive index pigment has been made dispersedly fixed to a binder resin and which comes different in transparency between a liquid-absorbed condition and a liquid-non-absorbed condition (see, e.g., Japanese Patent Publication No. S63-58711 ).
  • the porous layer conceals its underlying layer when it stands dry (it is in the liquid-non-absorbed condition), and turns transparent when a liquid such as water is made absorbed in the porous layer, whereby images such as letters or characters and patterns or designs can be formed, reflecting a color(s) the underlying layer has.
  • a moisture-sensitive color-changeable textile printing agent is also disclosed, containing finely particulate silicic acid and an iridescent pearl pigment; the agent being applied to a support of various types by printing (see, e.g., Japanese Patent Application Laid-open No. H01-260075 ).
  • This moisture-sensitive color-changing textile printing agent takes on white in virtue of the finely particulate silicic acid when it stands dry, and the finely particulate silicic acid turns transparent when it stands wet with water, where the color of the iridescent pearl pigment is perceivable with the eyes.
  • the color produced by the iridescent pearl pigment is not sharp when compared with colors produced by commonly available dyes and pigments.
  • a difficulty may come about such that the color of the substrate is limited to black color or dark colors in order for the color of the iridescent pearl pigment to be sufficiently perceivable with the eyes.
  • the present invention provides a drawing toy having a porous layer of which water is applied to form images such as letters or characters and patterns or designs, and which improves in commerciality and play performance by imparting brilliance to the images formed, and a drawing toy set using the same.
  • the drawing toy of present invention comprises a drawable member that can write or draw on, having a light-transmitting support and provided on the surface thereof a porous layer in which a low refractive index pigment has been made dispersedly fixed to a binder resin and which comes different in transparency between a liquid-absorbed condition and a liquid-non-absorbed condition, and a light source which irradiates the back surface of the drawable member with light.
  • the present invention may preferably require that at least one of the light-transmitting support and the porous layer contains a coloring agent; that a non-color-changeable layer containing a coloring agent is provided between the light-transmitting support and the porous layer and/or on the back surface of the light-transmitting support; that the coloring agent is selected from a fluorescent pigment, a fluorescent dye, a fluorescent brightening pigment and a fluorescent brightening dye; that the light-transmitting support holds the light source therein; that the drawing toy has a container which holds the light source therein, and the container has, at its part where the drawable member is disposed, a light-transmitting part which transmits light from the light source; that the drawing toy has a container which holds the light source therein, and the container is provided with an opening through which the drawable member is irradiated on the back surface thereof with the light from the light source, where the drawable member is so constructed as to be detachably mountable to the opening; that the container is provided with
  • Another embodiment of the present invention comprises the above drawing toy and a water-applying implement.
  • images such as letters or characters and patterns or designs formed by applying water to the porous layer are irradiated with light from through the back surface thereof, and hence the color the images have and the light act together to make the images perceivable with the eyes as images having brilliance. Accordingly, the present invention can provide a drawing toy which has a high commercial value and excellent performance in play, and a drawing toy set using the same.
  • water is applied to the porous layer standing dry that has been formed in the drawable member, to bring it into a liquid-absorbed condition, whereupon the porous layer becomes light-transmitting, and the drawable member is irradiated with light on its back surface by means of the light source, whereby the images at the liquid-absorbed areas are perceivable with the eyes in the state they have brilliance.
  • a drawing toy is provided according to the present invention.
  • any support may all be used as long as it is made of a material having light-transmitting properties.
  • a material may include glass, plastics, cloths such as textile, knitting, braid and non-woven fabric, porcelain, and paper.
  • the plastics may be exemplified by plastic molded products, and plastic sheets, of polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polymethyl methacrylate, polyacrylate, polystyrene, polycarbonate, cellulose triacetate, cellulose diacetate, polyvinyl alcohol, polyamide and so forth.
  • Plastic sheets of polyethylene, polypropylene, polyethylene terephthalate and polyvinyl chloride may preferably be used, as being excellent in flexibility and safety.
  • the support may be colorless light-transmitting, or may instead be semi light-transmitting or may be colored light-transmitting, as long as it has light-transmitting properties.
  • the porous layer provided on the light-transmitting support is a layer in which a low refractive index pigment has been made dispersedly fixed to a binder resin and which comes different in transparency between a dry condition and a liquid-absorbed condition.
  • the low refractive index pigment may preferably include silicic acid and salts thereof, barite powder, barium sulfate, barium carbonate, calcium carbonate, gypsum, clay, talc, alumina white and magnesium carbonate. These have refractive index within the range of from 1.4 to 1.8, and exhibit good transparency upon absorption of water.
  • the salts of the silicic acid may include aluminum silicate, aluminum potassium silicate, aluminum sodium silicate, aluminum calcium silicate, potassium silicate, calcium silicate, calcium sodium silicate, sodium silicate, magnesium silicate and magnesium potassium silicate.
  • the low refractive index pigment may also be used in combination of two or more types.
  • particle diameter of the low refractive index pigment there are no particular limitations on particle diameter of the low refractive index pigment. Those having a particle diameter of from 0.03 ⁇ m to 10.0 ⁇ m may preferably be used.
  • a low refractive index pigment that may preferably be used is a silicic acid.
  • the silicic acid may be silicic acid produced by a dry process, and silicic acid produced by a wet process (hereinafter “wet-process silicic acid”) is especially effective.
  • wet-process silicic acid silicic acid produced by a wet process
  • the silicic acid is produced as amorphous, non-crystalline silicic acid, and is roughly classified by its production process into silicic acid produced by a dry process (hereinafter “dry-process silicic acid”), which makes use of gas-phase reaction such as thermal decomposition of a silicon halide such as silicon tetrachloride, and the wet-process silicic acid, which makes use of liquid-phase reaction such as decomposition of sodium silicate or the like by acid.
  • dry-process silicic acid gas-phase reaction
  • thermal decomposition of a silicon halide such as silicon tetrachloride
  • wet-process silicic acid which makes use of liquid-phase reaction such as decomposition of sodium silicate
  • the silicic acid differs in structure between the dry-process silicic acid and the wet-process silicic acid.
  • the dry-process silicic acid forms a three-dimensional structure in which the silicic acid has densely combined, whereas the wet-process silicic acid has what is called a two-dimensional structure moiety in which the silicic acid has condensed to form a long molecular arrangement.
  • the wet-process silicic acid when used in the porous layer, is superior in irregularly light reflecting properties in a dry condition, compared with a system using the wet-process silicic acid, and hence can have a greater hiding power in a usual condition, as so presumed.
  • the water is made absorbed, and hence the wet-process silicic acid may preferably be used because it has a larger number of hydroxyl groups present as silanol groups on the particle surfaces than the dry-process silicic acid and is greatly hydrophilic.
  • the low refractive index pigment in the porous layer may preferably be used in a coating weight of from 1 g/m 2 to 30 g/m 2 , and more preferably from 5 g/m 2 to 20 g/m 2 , which may depend on its properties such as particle diameter, specific surface area and oil absorption. If it is in a coating weight of less than 1 g/m 2 , it is difficult to achieve any sufficient hiding power in the usual condition. If it is in a coating weight of more than 30 g/m 2 , it is difficult to achieve any sufficient transparency in the liquid-absorbed condition.
  • the low refractive index pigment is dispersed in a vehicle containing a binder resin as a binding agent, which is then coated on the light-transmitting support, followed by removal of volatile components by drying to form the porous layer.
  • the binder resin may include urethane resins, nylon resins, vinyl acetate resins, acrylate resins, acrylate copolymer resins, acrylic polyol resins, vinyl chloride-vinyl acetate copolymer resins, maleic acid resins, polyester resins, styrene resins, styrene copolymer resins, polyethylene resins, polycarbonate resins, epoxy resins, styrene-butadiene copolymer resins, acrylonitrile-butadiene copolymer resins, methyl methacrylate-butadiene copolymer resins, butadiene resins, chloroprene resins, melamine resins, and resin emulsions of all the foregoing, as well as casein, starch, cellulose derivatives, polyvinyl alcohol, urea resins and phenolic resins.
  • the low refractive index pigment and any of these binder resins may be mixed in such a proportion that the binder resin is in an amount of from 0.5 to 2 parts by weight based on 1 part by weight of the low refractive index pigment, and more preferably from 0.8 to 1.5 parts by weight based on 1 part by weight of the low refractive index pigment, which may depend on the type and properties of the low refractive index pigment. If the binder resin is in an amount of less than 0.5 part by weight based on 1 part by weight of the low refractive index pigment, it is difficult to achieve any practical film strength of the porous layer. If the binder resin is in an amount of more than 2 parts by weight based on 1 part by weight of the low refractive index pigment, the water may be poorly permeable into the porous layer.
  • the porous layer described above has a smaller binder resin proportion to the pigment and is hence less apt to have sufficient film strength. Consequently, for use in applications where abrasion resistance is required, it is preferred to use nylon resins or urethane resins among the above binder resins.
  • the urethane resins may include polyester type urethane resins, polycarbonate type urethane resins and polyether type urethane resins, any of which may be used in combination of two or more types. Also usable are urethane type emulsion resins in which any of the above resins has been dispersed in water by emulsification, and colloidal dispersion type (ionomer type) urethane resins in which the resin has been dissolved or dispersed in water by self-emulsification without requiring any emulsifying agent in virtue of the ionic groups of urethane resins (urethane ionomers) themselves having ionic properties.
  • urethane resins either of water-based urethane resins and oil-based urethane resins may be used.
  • what may preferably be used are water-based urethane resins, in particular, the urethane type emulsion resins and the colloidal dispersion type urethane resins.
  • any of the above urethane resins may be used alone, and may also be used in combination with other binder resin in accordance with the type of the light-transmitting support and the performance required as films.
  • the film strength may be improved by adding any desired cross-linking agent.
  • the binder resins illustrated above vary in affinity for water. By using a suitable combination of two or more of these, it is possible to regulate the time required for water to penetrate-into the porous layer, and degree of permeation, and the rate of drying after permeation. It is also possible to control the-above regulation by suitably adding a dispersant or a surface active agent.
  • the porous layer may be formed on the light-transmitting support by printing means such as screen printing, offset printing, gravure printing, coater printing, pad printing, or transfer; or brush coating, spray coating, electrostatic coating, electrodeposition coating, cast coating, roller coating or dip coating.
  • printing means such as screen printing, offset printing, gravure printing, coater printing, pad printing, or transfer; or brush coating, spray coating, electrostatic coating, electrodeposition coating, cast coating, roller coating or dip coating.
  • the drawable member obtained as described above may be incorporated with a coloring agent in the light-transmitting support or porous layer to have colored transparency so as to achieve various color-changes.
  • a non-color-changeable layer (colored light-transmitting layer) may also be provided between the light-transmitting support and the porous layer or on the back surface of the light-transmitting support so as to achieve various color-changes.
  • the coloring agent may include commonly available color dyes, and besides fluorescent pigments and fluorescent dyes, any of which may be used.
  • the drawable member that constitutes the drawing toy may be a single member, or may have a plurality of drawable members colored with coloring agents having different colors.
  • the drawing toy has the light source which irradiates the back surface of the drawable member with light.
  • the light source may include incandescent lamps, halogen lamps, luminescent lamps such as a fluorescent lamp, a metal halide lamp, a sodium lamp and a mercury lamp, light-emitting diodes, lasers, and ultraviolet lamps.
  • the light source may be so set up as to directly irradiate the back surface of the drawable member with light, or may instead preferably be so set up as to irradiate the back surface of the drawable member with light as far as possible by indirectly irradiating the back surface of the drawable member with light via an optical member which reflects or refracts the light from the light source.
  • the light source may be a light source kept always turned on, or may instead be so set up that it can be switched between being always turned on and being turned on or off so as to be set variable, or the light source itself may be moved or rotated so as to be set variable.
  • a drawable member may be used in which a coloring agent selected from a fluorescent pigment, a fluorescent dye, a fluorescent brightening pigment and a fluorescent brightening dye is blended in the light-transmitting support or porous layer, or a drawable member may be used in which a non-color-changeable layer containing a coloring agent selected from a fluorescent pigment, a fluorescent dye, a fluorescent brightening pigment and a fluorescent brightening dye is provided between the light-transmitting support and the porous layer or on the back surface of the 1 light-transmitting support.
