The present invention relates to a correction fluid, and more specifically, the present invention relates to a correction fluid that makes it possible to rewrite the paint film of a correction area with a fountain pen, felt-tip pen, etc. that uses water-based ink, and has good drying properties of the rewritten handwriting, resulting in color fading (discoloration of the handwriting). The present invention relates to a correction fluid that allows a coating film to be obtained with less concentration (state of thinning). Conventionally, areas that have been corrected with oil-based correction fluid are hydrophobic, so when rewriting with a fountain pen, felt-tip pen, etc. that uses water-based ink, the water-based ink is repelled, making it difficult to rewrite. Further, even if it is possible to write again, there is a problem in that the dryness of the handwriting is poor, the density of the handwriting becomes thin, and so-called color fading phenomenon occurs. In order to solve the above-mentioned problems, the present inventors have finally completed the present invention as a result of various studies on substances to be added to oil-based correction fluid. The gist of this invention is a correction fluid consisting of at least a resin soluble in an organic solvent and a solid acid. In the present invention, when writing with water-based ink on the paint film of the corrected area using solid acid, why is it possible to re-write without repelling the water-based ink, and the drying properties of the re-written handwriting are good and the handwriting is good? Although it is not certain whether the color fading is less, the water-based ink written on the touch-up film is adsorbed by the porous solid acid, which improves the drying properties of the handwriting. It is thought that because the adsorbed water-based ink exhibits acidity and the dye develops a deep color, it is possible to prevent discoloration of handwriting as much as possible. The composition of the present invention will be explained below. The white pigment is used to hide handwriting, and various types of titanium oxide such as rutile type and anatase type can be used, and commercially available ones include:
Taitone SR-1, Taitone R-650, Taipei R-3L, Taipei R-310, A-110, A-150, Taipei R-5N (manufactured by Sakai Chemical Industry Co., Ltd.) Taipeku R-580, Same R
-550, R-930, A-100, A-220, (manufactured by Ishihara Sangyo Co., Ltd.), Kronos KR-310, KR
-380, KR-480, KA-10, KA-20,
Examples include KA-30 (manufactured by Titan Kogyo Co., Ltd.), and in consideration of other components, the amount used is preferably 20 to 50% by weight based on the total amount of the correction fluid. Organic solvents are used for dissolving resins, adjusting viscosity, etc., and include hydrocarbons such as toluene, xylene, n-heptane, n-octane, cyclohexane, and methylcyclohexane, 1,1,1-trichloroethane, and tetrachloroethane. Halogen hydrocarbons such as chlorethylene, ethers such as 1,4-dioxane, n-butyl ether, trioxane, ketones such as ethyl methyl ketone and methyl-n-propyl ketone, esters such as propyl formate and ethyl acetate, etc. Considering the drying time of the paint film in the corrected area, it is preferable to use one with a boiling point of 70°C to 150°C, and it can be used alone or in combination, and the amount used is 30 to 150°C based on the total amount of correction liquid. 60% by weight is preferred. Note that if a paraffinic hydrocarbon such as n-heptane or n-octane or a naphthenic hydrocarbon such as cyclohexane or methylcyclohexane is used as an organic solvent, it is possible to correct even the handwriting of an oil-based ink. Examples of resins soluble in organic solvents include acrylic resins, alkyd resins, vinyl resins, and polyester resins, which can be used alone or in combination, and the amount used is based on the total amount of correction fluid. 5 to 20% by weight is preferred. Specific examples of solid acids that are the essence of the present invention include naturally occurring clay minerals such as acid clay,
Activated clay, which is activated clay by treating acid clay or similar clay with acid, silica-alumina, which is a mixture of silica and alumina, aluminum oxide, vanadium oxide, sulfuric acid, phosphoric acid, and other acids, such as silica gel, alumina, etc. solidified acid attached to a carrier. One or more of the above-mentioned solid acids can be used, and if the amount used is less than 1% by weight based on the white pigment, the effect will be small, and if it is more than 100% by weight,
Since the oil absorption amount of the solid acid is larger than that of the white pigment, the correction coating film tends to become brittle and difficult to rewrite, so the amount is 1 to 100% by weight, more preferably 2 to 50% by weight. In addition to the above ingredients, coloring pigments are added to match the color tone with the writing surface such as paper, and extender pigments such as silica and calcium carbonate are added to improve hiding power.
Dispersants and anti-settling agents are used to stabilize the dispersion of pigments.
A thickener may be added to adjust the viscosity, and a flow improver or a leveling agent may be added in small amounts to improve coating performance. The correction fluid of the present invention is produced by mixing the above components in a ball mill,
It can be obtained by dispersing and mixing using a stirring disperser such as an attritor or a sand grinder. The thus obtained coating film at the area corrected with the correction liquid of the present invention can be rewritten with water-based ink, and the rewritten handwriting dries well and has little color fading. Hereinafter, the present invention will be described in more detail with reference to Examples, where "parts" in the Examples indicate "parts by weight."
