Description

本発明は、顔料と、有機溶剤と、成膜性の樹脂とを含有する、塗膜乾燥に優れる油性の液状組成物に関するものである。   The present invention relates to an oily liquid composition excellent in drying of a coating film, which contains a pigment, an organic solvent, and a film-forming resin.

有機溶剤を媒体として使用した、所謂油性の液状組成物は、ガラスや樹脂成形品、金属面などに塗布しても濡れ易く塗布跡を形成しやすい。そして、成膜性の樹脂を使用したものでは、圧塗りの塗膜が形成しやすかったり、高隠蔽性の塗布跡が形成しやすく、ペイントマーカー、ネオンボードマーカー、修正液、ネイルカラー、下塗り用絵の具、補修用目止めマーカーなど、様々な用途展開が考えられる。
特に、修正液においては、顔料として隠蔽効果の高い酸化チタンが使用され、溶剤には、一般的には、修正する筆跡を溶かさなく且つ塗膜乾燥性が良い低沸点のシクロパラフィン系溶剤等が提案がなされている。
例えば、特開平03−285966号公報に記載の発明ではシクロぺンタン系溶剤が(特許文献1参照)、特開平07−258589号公報に記載の発明では、シクロヘキサン、メチルシクロヘキサン、エチルシクロヘキサン(特許文献2参照)が示されている。
A so-called oily liquid composition using an organic solvent as a medium easily wets and forms a coating mark even when applied to glass, a resin molded product, a metal surface, or the like. And with those using film-forming resin, it is easy to form a pressure-applied coating film, and it is easy to form coating marks with high concealment, for paint markers, neon board markers, correction fluids, nail colors, undercoats Various applications such as paints and repair markers are conceivable.
In particular, in the correction liquid, titanium oxide having a high hiding effect is used as a pigment, and the solvent is generally a low-boiling point cycloparaffinic solvent that does not dissolve the handwriting to be corrected and has good film drying properties. Proposals have been made.
For example, in the invention described in JP-A-03-285966, a cyclopentane solvent is used (see Patent Document 1), and in the invention described in JP-A-07-258589, cyclohexane, methylcyclohexane, ethylcyclohexane (Patent Document). 2).

特開平03−285966号公報(2頁、右上欄の19行〜20行目、左下欄の1行〜2行目)JP 03-285966 A (2 pages, 19th to 20th lines in the upper right column, 1st to 2nd lines in the lower left column) 特開平07−258589号公報(3頁、4段、21〜23行目)JP 07-258589 A (3rd page, 4th stage, 21st to 23rd lines)

上述のような有機溶剤を使用した修正液は、それなりに、筆跡乾燥性は早いものであるが、より沸点の低い有機溶剤を使用するほど、塗布跡の表面のみが乾燥してしまい、表面のみを覆う幕を形成して膜の内部に有機溶剤を取り残してしまうことがあった。これは、乾燥していると思った塗布跡を手などで押すと内部の溶剤が吹き出てくるなど、手や他の被塗布面を汚すことになり好ましくないばかりか、修正液においては、塗布跡上をボールペンなどで再筆記した場合に幕を破壊し再筆記不能となるなどの問題がある。   The correction liquid using the organic solvent as described above has a fast handwriting dryness as it is, but as the organic solvent having a lower boiling point is used, only the surface of the application mark is dried, and only the surface is dried. In some cases, an organic solvent is left behind inside the film. This is not preferable because pressing the application mark that is thought to be dry with your hand will cause the internal solvent to blow out, which may contaminate your hand and other surfaces to be applied. There is a problem that when rewriting on the trace with a ballpoint pen, the curtain is destroyed and rewriting becomes impossible.

即ち、本発明は、シクロヘキサン、メチルシクロヘキサン、エチルシクロヘキサンから選ばれる1種もしくは2種以上の有機溶剤と、顔料と、成膜性の樹脂と、板状のカオリナイト粒子と球状の石英粒子との複合物とを少なくとも含む修正液を要旨とする。 That is, the present invention includes one or more organic solvents selected from cyclohexane , methylcyclohexane, and ethylcyclohexane, a pigment, a film-forming resin, plate-shaped kaolinite particles, and spherical quartz particles. The gist is a correction fluid containing at least a composite .

本発明の板状のカオリナイト粒子と球状の石英粒子との複合物は、成膜性樹脂が成膜する際に立体障害を形成するものと推察され、これにて形成される空間から有機溶剤が揮発や、吸収面への塗布であれば浸透とを助けるため、より早く乾燥した塗布跡を形成することができるものと推察される。
また、特に、有機溶剤としてシクロヘキサン、メチルシクロヘキサン、エチルシクロヘキサンから選ばれる1種もしくは2種以上の混合物を使用し、板状のカオリナイト粒子と球状の石英粒子との複合物を使用すると、媒体と粒子との関係における膨潤効果が発揮されにくいので、上述の有機溶剤が移動する空間が形成されやすく、より早い塗膜乾燥性が得られるものである。
The composite of the plate-like kaolinite particles and spherical quartz particles of the present invention is presumed to form steric hindrance when the film forming resin forms a film, and the organic solvent is formed from the space formed thereby. If it is applied to the absorbing surface, it is presumed that a dried application mark can be formed earlier because it helps the penetration.
In particular, when one or a mixture selected from cyclohexane, methylcyclohexane, and ethylcyclohexane is used as the organic solvent, and a composite of plate-shaped kaolinite particles and spherical quartz particles is used, Since the swelling effect in relation to the particles is difficult to be exhibited, a space in which the above-mentioned organic solvent moves is easily formed, and faster coating film drying properties can be obtained.

本発明の高液状組成物は、使用する目的に応じて、例えば、ボールペンなどで筆記した消しゴムで消えない文字や、印刷物の一部を隠蔽する際には、弁付きの小口や繊維集束体を塗布先とした液内蔵式の塗布具や、容器内に入れた液を刷毛などで目的の部分に塗るタイプの修正液に使用する
顔料としては、酸化チタン、特にアルミナ又はシリカにて処理した酸化チタンが隠蔽性及び分散性の面で好ましく、有機溶剤は、筆跡を溶かさない非極性有機溶剤の中のシクロパラフィン系有機溶剤が、塗布した後の塗膜の乾燥の面を考慮すると、メチルシクロヘキサンが好ましい。成膜性の樹脂は、使用する有機溶剤に溶解し、皮膜強度が強く、分散性の良いアクリル酸エステル系樹脂が好ましい。本発明のポイントである板状のカオリナイト粒子と球状の石英粒子との複合物は、塗膜乾燥性向上を付与する重要な役割を果たす粒子である。
Depending on the purpose of use, the high-liquid composition of the present invention may be used, for example, when concealing characters that cannot be erased with an eraser written with a ballpoint pen or a part of a printed matter, or with a fork with a valve or a fiber bundle. It is used for a liquid built-in type applicator as the application destination, or a correction liquid of the type in which the liquid in the container is applied to the target part with a brush or the like.
As the pigment, titanium oxide, particularly titanium oxide treated with alumina or silica, is preferable in terms of concealability and dispersibility, and the organic solvent is a cycloparaffinic organic solvent in a nonpolar organic solvent that does not dissolve the handwriting, Considering the aspect of drying the coated film after coating, methylcyclohexane is preferred. The film-forming resin is preferably an acrylic ester resin that dissolves in the organic solvent to be used, has high film strength, and good dispersibility. The composite of plate-like kaolinite particles and spherical quartz particles, which is the point of the present invention, is a particle that plays an important role in imparting improved coating film drying properties.
