- Japanese Patent Application Laid-Open No. Hei 6-287497 discloses a white pigment, a plate-like silicate and a water-soluble resin, Inks with viscosity values between 600 and 1000 centimeters have been reported. However, this ink has a problem that the viscosity value is high and the followability during writing is not good.
- Japanese Patent Application Laid-Open No. 7-216283 discloses that a white pigment and a nonionic surfactant having an HLB of 17.0 or more have a viscosity value of 600 to 500 Inks have been reported. This ink also has a high viscosity value, so it has good followability when writing. Does not solve unfavorable problems.
- Japanese Patent Application Laid-Open No. 8-129169 discloses that a viscometer is made of titanium oxide, a thickening water-soluble resin, and a sugar alcohol, has a viscosity value of 600 to 500 centimeters, and rotates a viscometer. Inks have been reported in which the viscosity index obtained by the number difference is 2 or more. However, even if this viscosity index is applied, the ink followability of quick writing and the line division of the writing line are not eliminated, and only white pigment is added as a coloring material. Above, there is a problem that the marking performance is inferior. Disclosure of the invention
- the object of the present invention is to improve the water resistance and weather resistance by using a titanium oxide and a complementary colorant as a coloring agent and using a resin emulsion, and to provide a poster-one-color clear tone even in writing paper having a high density.
- An object of the present invention is to provide a water-based white pigment ink for a ball-point pen, which is capable of obtaining a writing line, suppresses sedimentation and deterioration of titanium oxide even when stored for a long period of time, and has good followability and enables continuous writing.
- the present invention comprises a titanium oxide and a complementary colorant, a resin emulsion, a thickener for preventing sedimentation and separation, a polar solvent, water and other modifiers required for water-based inks for a ballpoint pen.
- This is a water-based white-colored pigment for ballpoint pens, having the power and exhibiting various color tones of poster one color.
- the titanium oxide used in the present invention is used as a white pigment that imparts concealment to a written line.
- titanium oxide There are two types of titanium oxide, rutile type and anatase type, depending on the crystal structure. Both types can be used.
- the use amount thereof is preferably 10 to 40% by weight based on the total amount of the aqueous ink, and two or more kinds of titanium oxide products can be used in combination.
- the complementary colorant is a pigment having an average particle diameter of 100 nm or more or a water-insoluble polymer having an average particle diameter of 200 nm or more in order to color a color other than white, which is the background color of titanium oxide particles.
- a pseudo pigment obtained by dyeing fine particles with a dye is used.
- the pigment itself has excellent water resistance and weather resistance, and gives a semi-permanent writing line.However, when present together with the resin emulsion, the drawing line has various colors regardless of the background color and color tone of the writing paper. The color can be iris.
- pigments used are: carbon black, titanium black, zinc white, red iron oxide, chromium oxide, iron black, cobalt bull, iron oxide yellow, viridian, zinc sulfide, lithium, bonbon, cadmium, red, cadmium.
- Pseudo-pigment in which high-molecular fine particles are dyed is dyed with resin consisting of spherical fine particles having a small specific surface area, has low surface adsorption, small adsorption and cohesion of particles, and low adhesion with titanium oxide.
- resin consisting of spherical fine particles having a small specific surface area
- the coagulation action is small.
- the particle size is large, the color development will be clear even on writing paper with a dark hue, especially if it has an average particle size of 20 O nm or more, not only color development but also prevention of sedimentation of titanium oxide is possible Is more preferable.
- the viscosity agent is used to suppress the sedimentation of titanium oxide and to provide appropriate fluidity as an ink for a ballpoint pen.However, the effect is not reduced when used together with a titanium oxide or a resin emulsion in an aqueous ink. It is necessary to select one that has the property of:
- guar gum locust bingham, galactomannan, pectin and its derivatives, syllium sway gum, tama gentian gum, microbial xanthan gum, leosan gum, ramzan gum, gerang gum, which are natural polysaccharides and seed polysaccharides Seaweed polysaccharides such as carrageenan, alginic acid and its derivatives, resin polysaccharides such as carrageenan, cellulose and derivatives thereof, and synthetic polymers, such as polyacrylic acid and its cross-linked copolymer, polyvinyl alcohol, and polyvinylpyrrolidone. And its derivatives, polyvinyl methyl ether and its derivatives, and the like.
- microbial gums are characterized by a strong viscosity-imparting effect and stable physical properties even when stored for a long period of time.
- Polyacrylic acid and its cross-linked copolymer have a stable characteristic with respect to the cohesiveness of pigments and the propagation of various bacteria, but tend to be less viscous than natural polysaccharides.
- One or more of the above thickeners can be selected and used depending on the amount and type of titanium oxide / complementary colorant in the ink component.
- the amount of the thickener used is preferably from 0.1% by weight to 1.5% by weight of the whole ink.
- the amount of addition varies depending on the type of thickener. For natural polysaccharides, the amount is preferably 0.1% by weight to 0.8% by weight, and for the synthetic polymer type, 0.1% by weight to 1.5% by weight is preferred. preferable.
- the amount of the thickener is small, sedimentation of the titanium oxide particles is liable to occur, and if the amount is more than 1.5% by weight, the flowability of the ink decreases, and poor writing due to poor followability of the ink tends to occur. .
- Fluidity can be judged by ink viscosity.For example, when measured with a general rotational viscometer, E-type viscometer, to prevent sedimentation of titanium oxide particles, 25 ° C, l rpm The viscosity value must be 50 OraPa's or more, and in order to impart this viscosity, the amount of the thickener added is required. On the other hand, if the viscosity value is more than 500 OmPa-s, the fluidity of the ink will decrease, and the ink follow-up property and the supply of the ballpoint pen from the pen tip to the writing paper will be poor. The amount of agent added must be reduced.
- the resin emulsion is necessary to improve the ink line drawing color on dark writing paper and to suppress the sedimentation and separation of titanium oxide particles.
- the resin particles dispersed in water and the aqueous solvent have an average particle size of 20 O nm or more, the resin particles are characterized by exhibiting white color due to light reflection and refraction effects. The more the reflection effect increases, the more the white opacity increases. With the hollow resin emulsion, which can be expected to increase the refraction effect, white hiding properties can be further expected, and excellent ink drawing line coloring properties are recognized.
- a resin emulsion having a large particle diameter is present between the titanium oxide particles having a large particle diameter, thereby suppressing adsorption and aggregation of the titanium oxide particles. It suppresses the increase of particles and exhibits the effect of preventing sedimentation.
- particles with a particle size of 20 Onm or more penetrate into the paper fibers of the writing paper serve as a seal, and suppress the penetration of ink, so that clear writing lines can be given even on dark hue writing paper. it can.
- resin emulsions examples include Acronal YJ-1556D, Acronal S-400 (Mitsubishi Chemical), Boncoat AB-735, Boncoat AN-868 (Dainippon Ink Chemical), Microgel E-3101 , Microgel MP E-13 (made by Nippon Paint), STADEX-SC-041-S, STADEX-SC-051-S (made by Nippon Synthetic Rubber).
- hollow resin emulsions include Lo-Pake OP-62, Koku-I-Pake OP-84J (manufactured by Rohm & Haas), and Nippol MH-5055 (manufactured by Zeon Corporation).
- the amount of the resin emulsion to be added is preferably 5.0% by weight to 25.0% by weight based on the weight of the resin particles themselves. If the amount used is less than 5.0% by weight, the background color of the writing paper with a dark hue is not sufficiently concealed or clogged, and the poster color cannot be obtained in a clear color. It will appear white. In addition, aggregation of the titanium oxide particles cannot be suppressed, and the particles tend to settle. When the used amount is 25.0% by weight or more, the interaction with the thickener becomes strong, and although the viscosity value is small, the fluidity of the ink decreases and the writing property tends to deteriorate. . Therefore, the amount of the resin emulsion added is preferably 5.0% by weight to 25.0% by weight in terms of the weight of the resin particles themselves.
- Polar solvents are used as inks for water-based ballpoint pens for various qualities, for example, to prevent ink drying at the pen tip and to prevent ink from freezing at low temperatures.
