Yet existing these use the aqueous ink composition of aluminium powder pigment or pearl pigment to be difficult to obtain having the person's handwriting of strong light sense.
The objective of the invention is, a kind of like this bright water printing ink composition that is used for ballpoint pen etc. is provided, it is compared with in the past the use aluminium powder pigment or the aqueous ink composition of pearl pigment, can obtain having the more person's handwriting of the bright sense of high light.
For achieving the above object, the present inventor has carried out deep research, found that, when aluminium powder pigment through being that the pulverization process of grinding aid and its median size are when (being 30-60 μ m better) with oleic acid more than 15 μ m, to contain this aluminium powder pigment and water soluble resin, the bright water printing ink composition of water-miscible organic solvent and water is used for writing appliances such as ballpoint pen, its printing ink person's handwriting will manifest the sense of intensive light. and find, when aluminium powder pigment through being that the pulverization process of grinding aid and its median size are when (being 30-60 μ m better) with the stearic acid more than 15 μ m, to contain this aluminium powder pigment and water soluble resin, the bright water printing ink composition of water-miscible organic solvent and water is used for writing appliances such as ballpoint pen, and its printing ink person's handwriting also can manifest the sense of intensive light.
The aqueous ink composition of the present invention that will have an above-mentioned composition is used for writing appliance such as ballpoint pen to be write, and its person's handwriting can manifest the sense of intensive light.
Aluminium powder pigment
The aluminium powder pigment that uses among the present invention for example obtains as aluminum paste (being commonly called as aluminium paste) by the following method: oleic acid or stearic acid are mixed in the mineral spirits and with it as grinding aid disperse the back pulverize with ball mill. and in addition, for example preferably use by in above-mentioned aluminum paste, adding and the water-resisting type aluminum slice slurry (water-resisting type aluminium powder pigment or water-resisting type aluminum slice color compositions) that obtains such as in mixing tank, mix behind inorganic phosphate, fatty compounds, tensio-active agent, water, the pure and mild hydrocarbon ils of hydratability.Generally speaking, so long as the aluminium powder pigment of crossing as the grinding aid pulverization process with oleic acid or stearic acid then can be any.
If the aluminium powder pigment of pulverizing as grinding aid with oleic acid; then since oleic acid the absorption of aluminium powder pigment particle surface become thick and polarity also big; person's handwriting that forms or the right and wrong of filming (metal-powder) are floated (non-leafing) type; aluminium powder pigment is at person's handwriting or in filming; thus, each aluminium powder pigment exists with various angular orientation.On the other hand; if the aluminium powder pigment that replaces above-mentioned oleic acid to pulverize with stearic acid as grinding aid; then stearic acid the absorption of aluminium powder pigment particle surface become intensive and polarity little, like this, the person's handwriting of formation or to film be that (metal-powder) floats (leafing) type.In above-mentioned situation, because the surface that aluminium powder pigment concentrates on person's handwriting or films, therefore, the orientation of each aluminium powder pigment particle is parallel with person's handwriting or coated surface basically.But has polar resin (varnish resin) owing to contain; same with the above-mentioned aluminium powder pigment of pulverizing as grinding aid with oleic acid; become non-floating type person's handwriting or film and aluminium powder pigment at person's handwriting or in filming, therefore, each aluminium powder pigment exists with various angular orientation.That is, if the aluminium powder pigment of pulverizing as grinding aid with stearic acid, then contain make aluminium powder pigment not buoyant have polar or highly oxidized resin is very important.The useful alkaline neutraliser of the example of these resins has carried out electrolysis, has imported hydroxyl, ether, carried out water soluble resins such as hydroxylated Synolac, melmac.
In addition, in the present invention, for the person's handwriting that makes ballpoint pen etc. shows the sense of intensive light, the median size of aluminium powder pigment particle is more than 15 μ m, and the big particle diameter that is preferably 30-60 μ m also is very important.If less than 15 μ m, even then aluminium powder pigment is orientated with float state at person's handwriting or in filming, but owing to the person's handwriting as ball pen ink, its thin slice particle is too small, and therefore, light is poor.And if surpass 60 μ m, even then adjust the content and the ball diameter of above-mentioned aluminium powder pigment, when using as ball pen ink, be difficult for from nib flowing out, be unfavorable therefore.If the particle diameter of above-mentioned big particle diameter aluminium powder pigment is 30 μ m or surpasses 30 μ m, then can make more intensive light sense of person's handwriting.
15 μ m), " WXM7640 " that produce of japan Aluminum Co., Ltd (median size: 17 μ m), " WXM5422 " (median size: 19 μ m), " WXM1440 " (median size: 30 μ m), " WXM1415 " (median size: 51 μ m), " WXM7493 " (median size: 60 μ m) such aluminium powder pigment for example has following commodity: " AW7000R " that Asahi Kasei Corporation produces (median size:.The aluminium powder pigment that these median sizes are different can use separately, also can share more than two kinds.

Synthetic resin emulsion
As mentioned above, the present inventor is the person's handwriting that obtains having strong light sense, and discovery should be used the big particle diameter aluminium powder pigment of crossing as the grinding aid pulverization process with oleic acid and stearic acid in the ink composite that contains water-soluble tackifying resin, water-miscible organic solvent and water.Compare with pearl pigment with the small particle size aluminium powder pigment of crossing for the grinding aid pulverization process with other lipid acid or mineral acid, use above-mentioned big particle diameter aluminium powder pigment can make person's handwriting produce stronger light sense.
Yet, contain water soluble resin (especially water-soluble tackifying resin) though bright water-thinned printing ink can improve the adhesivity of above-mentioned big particle diameter aluminium powder pigment by water-soluble tackifying resin to a certain extent, but the present inventor finds, because the shape of above-mentioned big particle diameter aluminium powder pigment is big, therefore, be difficult to big particle diameter aluminium powder pigment be adhered on the base material securely with water-soluble tackifying resin.Therefore, after writing with the water color ink that contains above-mentioned big particle diameter aluminium powder pigment, above-mentioned big particle diameter aluminium powder pigment can be easily because friction waits peel off, be difficult to make person's handwriting to produce the sense of intensive light constantly, have the poor durability of the person's handwriting that light feels.
Given this, provide water color ink with following characteristic (especially writing appliance use, the bright water-thinned printing ink used of ballpoint pen specifically) become an important problem: this bright water-thinned printing ink can not make ink characteristics and write suitability and descend, and can not hinder the intensive light sense effect that produces by mixing above-mentioned big particle diameter aluminium powder pigment, can improve the adhesivity of above-mentioned big particle diameter aluminium powder pigment, make person's handwriting produce stronger light sense constantly base material.
For finishing above-mentioned problem, the present inventor has carried out deep research, found that, contain as above-mentioned big particle diameter aluminium powder pigment, water soluble resin, water-miscible organic solvent and water that must composition and also contain and make above-mentioned big particle diameter aluminium powder pigment adhere to paper applied things such as (as write and use paper) to finish above-mentioned problem with the bright water-thinned printing ink of the binder constituents (adhered resin composition) that is replicated base material such as thing.
On the other hand, adhere to applied thing securely, be replicated on the base materials such as thing, can consider to use water-soluble synthetic resin as binder constituents in order to make so big particle diameter aluminium powder pigment.But, if big particle diameter aluminium powder pigment is adhered to securely, improve its content according to the kind of water-soluble synthetic resin, then may produce detrimentally affect to the solvability of tackifying resin, the dispersiveness of tinting material.In addition, the visco-elasticity of printing ink is descended significantly, suitability is write in influence.In addition, even applied thing, the adhesivity that is replicated base materials such as thing are obtained performance, but if the intensive light sense of above-mentioned big particle diameter aluminium powder pigment in person's handwriting descended, then such water color ink remains unfavorable.
The present inventor further in depth studies, found that, if use synthetic resin emulsion as making above-mentioned big particle diameter aluminium powder pigment adhere to applied thing, being replicated the binder constituents on the base material such as thing, then can improve above-mentioned big particle diameter aluminium powder pigment to the adhesivity of for example paper base materials such as (as write and use paper) and can not make it lose light, and finish the present invention thus.
Therefore, with the above-mentioned aqueous ink composition of the present invention that contains big particle diameter aluminium powder pigment at applied thing, be replicated on the thing base materials such as (as paper, metal, plastics, fibre products etc.) write or be coated with, when duplicating, can improve big particle diameter aluminium powder pigment to applied thing, be replicated the adhesivity of base materials such as thing, make person's handwriting have weather resistance, and can make person's handwriting continue to produce the sense of intensive light.This is the big particle diameter aluminium powder pigment that the film sexual compatibility has big lamella shape of making owing to synthetic resin emulsion, can not hinder the intensive light sense that produces by mixing above-mentioned big particle diameter aluminium powder pigment, make big particle diameter aluminium powder pigment can adhere to applied thing securely, be replicated due to the base material such as thing.
And, because binder constituents of the present invention (adhered resin composition) is not a water-soluble synthetic resin, but synthetic resin emulsion, therefore, it is less that the characteristics such as visco-elasticity of the dispersiveness of the solvability of the water-soluble tackifying resin that mixes simultaneously, tinting material and printing ink are produced dysgenic situation.Thus, the color that printing ink of the present invention can not influence ink viscosity, write suitability and person's handwriting can improve the adhesivity of above-mentioned big particle diameter aluminium powder pigment.
According to above-mentioned situation, the bright water-thinned printing ink that contains above-mentioned big particle diameter aluminium powder pigment of the present invention can not make ink characteristics and write decline such as suitability, and can not hinder the height surface smoothness that glass has, compare with the aqueous ink composition of bright pigment such as existing use aluminium powder pigment, pearl pigment, can make person's handwriting continue to produce stronger light sense.
Synthetic resin emulsion of the present invention is not particularly limited, so long as the synthetic resin emulsion of water dispersible gets final product.But consider ink characteristics and write suitability that used synthetic resin emulsion should not influence solvability, the ink viscosity of water-soluble tackifying resin, the dispersiveness and the printing ink colour developing of tinting material.In addition, can not hinder the intensive light sense effect that produces by mixing big particle diameter aluminium powder pigment.
In addition, the minimum film temperature of making of synthetic resin emulsion should be below 20 ℃.If the minimum film temperature of making of synthetic resin emulsion is below 20 ℃, especially below 0 ℃, much less (about 25 ℃) are then at normal temperatures, even in the place of cold, also can form film, thereby can improve the adhesivity of person's handwriting to base material.
Also have, synthetic resin emulsion preferably has anionic property or nonionic.Synthetic resin emulsion with anionic property or nonionic for example can be by making synthetic resins by anionic property or non-ionic monomer or obtaining by use anionic property or non-ionic emulsifier.Use has the synthetic resin emulsion of anionic property or nonionic, can improve the stability of printing ink.
Have, synthetic resin emulsion should be worked as printing ink pH can not affect the dispersiveness of toner and the solvability of water-soluble tackifying resin when above 6 again.
Consider that from above-mentioned angle used synthetic resin emulsion for example can be acrylic acid or the like synthetic resin emulsion, styrene-propene acids synthetic resin emulsion, vinyl-acetic ester class synthetic resin emulsion.The suitable example of acrylic acid or the like synthetic resin emulsion has the acrylate copolymer synthetic resin emulsion.The suitable example of styrene-propene acids synthetic resin emulsion has the copolymer in cinnamic acrylic ester synthetic resin emulsion.In addition, for example vinyl-acetic ester synthetic resin emulsion, vinyl-acetic ester-acrylate copolymer synthetic resin emulsion are the vinyl-acetic ester class synthetic resin emulsions that suits.These synthetic resins can use separately, also can share more than two kinds.
Specifically, the example of acrylic acid or the like synthetic resin emulsion comprises the commodity " Nikasol FX336 " by name that Japanese Carbide Industrial Co., Ltd produces (minimum film temperature<0 ℃ of making, pH 7.5,200mPas), commodity are called " Nikasol A-02 " (minimum film temperature<0 ℃ of making, pH 7.0,500mPas), commodity are called " Nikasol FH-011A " (minimum film temperature<0 ℃ of making, pH 7.0,150mPas) and the commodity " Mowinyl 231 " by name produced of ClariantPolymer company (minimum film temperature<0 ℃ of making, pH 4.0, viscosity 500-1500mPas) synthetic resin emulsion etc.Above-mentioned viscosimetric analysis is at 25 ℃ of numerical value that record with Brookfield viscometer.
Content to synthetic resin emulsion does not have special restriction, for example, in solid content, should account for the 0.1-40% of total weight.As less than 0.1%, then above-mentioned big particle diameter aluminium powder pigment descends to the adhesivity of base material; And if surpass 40%, then solid content is excessive, can membranization etc. occur being coated with at nib, and suitability is write in influence.In addition, the easy whitening of person's handwriting.For further improving the adhesivity of above-mentioned big particle diameter aluminium powder pigment to base material, synthetic resin emulsion preferably accounts at least 0.3% of total weight (in solid content).In addition, write suitability for further improving, synthetic resin emulsion preferably accounts for 20% of total weight (in solid content).That is, the optimum content of synthetic resin emulsion is 0.3-20 weight %.

The making of sample
Below, each ink composite of embodiment and comparative example shown in the table is filled to by an one end and stainless ball-point pen tip (pearl material: in the printing ink storage portion that the polypropylene beam barrel of the hollow that silicon carbide) is connected forms, make each ballpoint pen sample that above-mentioned printing ink storage portion is housed.
Evaluation test
Write on commercially available loose leaf paper with these ballpoint pens, the light sense of each printing ink of the embodiment of his-and-hers watches 1 and comparative example is estimated respectively.
The evaluation of light sense is write state by visual inspection and is carried out, and the strong usefulness zero of light sense is represented, light sense usefulness * expression little or that do not have the light sense.
As seen from table, use the printing ink of embodiment 1,6,8,10 and 13, all can obtain manifesting the person's handwriting of light as the diamond.Use the printing ink of embodiment 2,4,9,11 and 14, all can obtain manifesting the person's handwriting of light as the aquamarine.Use the printing ink of embodiment 3,5,7,12 and 15, all can obtain the person's handwriting of light as the pink colour pearl (pearl pink).And the printing ink of use comparative example, resulting person's handwriting all turns white, and does not manifest light.Especially no matter whether the ink composite of embodiment contain adhered resin, compares with 12 ink composite with the comparative example 7,10,11 that contains pearl pigment, and many glittering points that send dazzling light are arranged on its person's handwriting.
The foregoing description is the ink composite that is applicable to ballpoint pen, but if light ink composite of the present invention contains with oleic acid and/or stearic acid is the aluminium powder pigment of median size more than 15 μ m that the grinding aid pulverization process is crossed, then also applicable to other writing appliances.If to contain with oleic acid and/or stearic acid is the aluminium powder pigment of median size more than 15 μ m that the grinding aid pulverization process is crossed to light ink composite of the present invention, also can be used for cosmetic material such as the makeup that face applied some make up, modified nail, the makeup of modifying toenail, nail varnish, mascara, eyeliner, eye black pigment used by women in ancient times to paint their eyebrows, lipstick, foundation cream and hair cosmetic with the makeup association area of various uses such as material etc.
