Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a handwriting of a water-based ink such as a fountain pen, a water-based felt-tip pen, a water-based ballpoint pen, a handwriting of an oil-based ink such as an oil-based ballpoint pen and an oil-based felt-tip pen, and printing on a typewriter or printer, and other printed matter ( (Hereinafter, abbreviated as letters, etc.) The present invention relates to a solid correction tool for concealing correction.

[0002]

2. Description of the Related Art Conventionally, handwriting of water-based ink or oil-based ink,
Then, in order to conceal and correct an image or the like by various printings, a white pigment, a resin, and a correction liquid containing a volatile solvent as a dispersion medium for dispersing the white pigment as a main component are applied to the retouched portion to conceal it, and this coating is applied. After the film was completely dried, a method such as rewriting on the coating film was used.

However, when such a correction liquid is used, a waiting time of ten to several tens of seconds is required from the application of the correction liquid to the complete drying of the coating film, so that the rewriting speed is high. There was a problem that it lacked. Therefore, various types of solid correction tools mainly composed of a concealing material and wax have been proposed to make the waiting time almost zero.

[0004]

However, when the correction surface is rewritten after the correction is made with the above solid correction tool, the correction coating film has a stronger non-absorption surface property than paper. As a result, handwriting repelling occurs (because the wettability of water-based ink is low) and handwriting dryness (handwriting is not only dried by evaporation of the solvent used in the ink, but also penetrated into the writing surface of the ink). There is a problem that it decreases).

[0005]

The present invention has been made based on these circumstances, and basically makes full use of the advantages of a solid correction tool and eliminates the cratering of rewritten handwriting. In addition, as a result of intensive studies to obtain a solid correction tool having good dryness of rewritten handwriting, it was finally found that a correction coating film which does not cause the above problems can be obtained by using hydrolyzed collagen. Was completed.

The subject matter of the present invention is a solid correction tool containing at least a concealing material, wax and hydrolyzed collagen.

The details will be described below. The hiding material is used for hiding characters and the like. White pigments such as zinc oxide, barium sulfate, calcium carbonate and titanium oxide can be mentioned, but titanium oxide is most preferably used from the viewpoint of hiding power. Titanium oxide can be used in various types such as rutile type and anatase type,
Specifically, Tietone SR-1, R-650, R
-3L, R-310, A-110, A-150,
Same R-5N (above, Sakai Chemical Industry Co., Ltd.), Taipaque R-550, same R-580, same R-930, same A-10.
0, A-220 (all manufactured by Ishihara Sangyo Co., Ltd.), Kronos KR-310, same KR-380, same KR-480, same KA-10, same KA-20, same KA-30 (above, titanium) Industrial Co., Ltd. etc. are mentioned. These white pigments may be used alone or in admixture of two or more. The amount used varies depending on the type of hiding material, but considering the hiding power for handwriting, etc., it is 4 with respect to the total amount of the solid correction tool.
0 to 90% by weight is preferred. If the amount of the hiding material used is less than 40% by weight, the hiding power for handwriting and images may be insufficient and characters may be seen through.
This is because if the amount exceeds 5% by weight, the coating film forming ability may decrease.

Wax is used to improve the coating performance. Animal waxes such as beeswax, whale wax, and white wax
Natural wax such as candelilla wax, carnauba wax, plant wax such as wax, montan wax, mineral wax such as ozokerite, paraffin wax, petroleum wax such as microcrystalline wax, Fischer-Tropsch wax, low molecular weight polyethylene and these And derivatives of montan wax, paraffin wax, microcrystalline wax, synthetic waxes such as cetyl alcohol, stearic acid, polyethylene glycol stearate, and castor wax. These waxes can be used alone or in admixture of two or more, and the amount used is
It is preferably 10 to 45% by weight based on the total amount of the solid correction tool.

The hydrolyzed collagen is used to prevent the cratering of rewritten handwriting and to improve the dryness of the rewritten handwriting. Hydrolyzed collagen is obtained by hydrolyzing collagen obtained by treating the skin or bones of animals such as cows and pigs with acid or alkali with acid or enzyme. As a specific example, Nutrilan I powder (manufactured by Henkel Hakusui Co., Ltd.), CCP-100P (average molecular weight 1)
000, manufactured by Nikko Chemical Co., Ltd., Nippi Peptide P
A-10 (molecular weight 1000), PA-20 (molecular weight 2)
000), the same PA-50 (molecular weight 5000), the same PA-
100 (molecular weight of 10,000 or more, manufactured by Nippi Co., Ltd.) and the like. These may be used alone or in admixture of two or more. The amount used is preferably 5 to 20% by weight based on the total amount of the solid correction tool. This is 5% by weight
This is because if the amount is less, the effect cannot be expected so much, and if it is more than 20% by weight, the solid correction tool is hard and the coating performance tends to deteriorate. Also, hydrolyzed collagen is
It is preferable to use a powder, but it is also possible to use a commercially available product provided in the form of a solution or by evaporating a solvent (such as water) during the manufacturing process.

In addition to the above components, if necessary, a filler such as mica, clay or kaolin, a coloring agent such as an organic or inorganic colored pigment, a plasticizer such as dibutyl phthalate, dioctyl phthalate or liquid rubber is used in combination. Of course you can.

In particular, the combined use with a high molecular weight surfactant shows a great effect. It is believed that this is to prevent the wax from covering the surface of the hydrolyzed collagen powder when manufacturing the solid correction tool. Specific examples of the high molecular weight surfactant include pronone 102, 104, 201, 202B and 2 obtained by reacting polypropylene glycol and polyethylene glycol.
04, 208, Unilube MB series, a copolymer of ethylene oxide and propylene oxide, 70DP-9
50B (above, Nippon Oil & Fats Co., Ltd. product) etc. are mentioned, The usage-amount is 2.5-5.0 weight% with respect to the solid correction tool whole quantity.

In the present solid correction tool, the above components are heated and mixed with stirring, and if necessary, kneaded with a kneader such as a kneader or a roll mill, and then poured into a mold in a molten state, or injection / pressurization or extrusion. It can be obtained by cooling and solidifying.

[0013]

Since the hydrolyzed collagen used in the solid correction tool according to the present invention is a hydrophilic substance, it imparts hydrophilicity to the coating film and improves wettability with respect to the ink, so that re-writing handwriting is less likely to cause cissing. Furthermore, since it has hygroscopicity, it is presumed that the ink written on the surface of the coating film is absorbed and the handwriting rewritten is improved in dryness.
