【発明の詳細な説明】
［産業上の利用分野］
本発明は水性インキ、特に蒸発を抑制し、長期間大気に
露出していても析出がなくかつ耐乾燥性に優れた特性を
有する水性インキに関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a water-based ink, particularly a water-based ink that suppresses evaporation, does not precipitate even when exposed to the atmosphere for a long period of time, and has excellent drying resistance. It is related to.
［従来の技術とその課題］
従来、水性インキで耐乾燥性を有するインキとしては、
グリコール系溶剤、グリコールエーテル系溶剤、グリコ
ールエーテルエステル系溶剤、アミン系溶剤等の水溶性
有機溶剤あるいは塩化リチウム又は塩化カルシウム等の
吸湿性無機化合物等をインキ組成成分として添加したも
のであったが。[Conventional technology and its issues] Conventionally, water-based inks with drying resistance include:
Water-soluble organic solvents such as glycol solvents, glycol ether solvents, glycol ether ester solvents, and amine solvents, or hygroscopic inorganic compounds such as lithium chloride or calcium chloride were added as ink composition components.
これらの化合物のみでは耐乾燥性が十分に満足するもの
が得られなかった。又耐乾燥性を向上するために尿素を
添加したものが知られているが、耐乾燥性を十分に満足
させるだけの尿素量を添加したインキでは経時において
尿素の結晶が析出してしまい、このインキを筆記具に用
いた場合、カスレや筆記不能というような問題を生じる
。It was not possible to obtain a product with sufficiently satisfactory drying resistance using only these compounds. In addition, inks containing urea added to improve drying resistance are known, but with inks that contain enough urea to fully satisfy drying resistance, urea crystals precipitate over time. When ink is used in writing instruments, problems such as blurring and inability to write arise occur.
［課題を解決するための手段］ 本発明は前記問題点に鑑みなされたものであり。[Means to solve the problem] The present invention has been made in view of the above problems.
着色剤と、水と、尿素及びチオ尿素を混合比尿素：チオ
尿素＝１：１〜９：１インキ全量に対し１０重量％以上
とを少なくとも含有してなる水性インキを要旨とするも
のである。The gist is a water-based ink containing at least 10% by weight or more of a colorant, water, urea and thiourea in a mixed ratio of urea:thiourea = 1:1 to 9:1 based on the total amount of the ink. .
以下、本発明の各成分について詳述する。Each component of the present invention will be explained in detail below.
着色剤としては水溶性の醜性染料、直接染料あるいは塩
基性染料等のほとんどの染料及び一般に市販されている
顔料が１種又は２種以上を適宜選択して使用できる。そ
の使用量はインキ全量に対して１〜２０重景％が好まし
い。As the colorant, one or more of most dyes such as water-soluble ugliness dyes, direct dyes, basic dyes, and generally commercially available pigments can be selected and used. The amount used is preferably 1 to 20% by weight based on the total amount of ink.
水は溶剤として用いるものであり、その使用量はインキ
全量に対して３０〜８０重量％が好ましい。 尿素及び
チオ尿素の混合比が尿素：チオ尿素＝１＝１〜９：１で
あるのは、尿素が１：１より少ないと十分な効果が得ら
れず、９：１より多いと析出という問題が起こる。又、
尿素及びチオ尿素の使用量がインキ全量に対して１０重
量％以上であるのは、１０重量％より少ないと十分な効
果が得られないためである。Water is used as a solvent, and the amount used is preferably 30 to 80% by weight based on the total amount of ink. The reason why the mixing ratio of urea and thiourea is urea:thiourea=1=1 to 9:1 is because if the urea content is less than 1:1, a sufficient effect cannot be obtained, and if the urea content is more than 9:1, precipitation will occur. happens. or,
The reason why the amount of urea and thiourea used is 10% by weight or more based on the total amount of the ink is that sufficient effects cannot be obtained if the amount is less than 10% by weight.
上記成分以外に水溶性有機溶剤、防腐剤、防錆剤、各種
界面活性剤、分散剤などを１種もしくは２種以上適宜使
用できるものである。In addition to the above components, one or more water-soluble organic solvents, preservatives, rust preventives, various surfactants, dispersants, etc. can be used as appropriate.
［作 用］
本発明の水性インキが何故結晶が析出しないのかについ
ては定かではないが、尿素分子中の酸素原子とチオ尿素
分子中の硫黄原子が水溶液中で引きあうことによって、
あたかも水の温度が上昇したのと同じ効果が現れ、尿素
及びチオ尿素の溶解度が高められることによって析出が
なく、耐乾燥性に優れたものになると思われる。[Function] It is not clear why crystals do not precipitate in the aqueous ink of the present invention, but the reason is that the oxygen atom in the urea molecule and the sulfur atom in the thiourea molecule attract each other in an aqueous solution.
It seems that the same effect appears as if the temperature of water were raised, and the solubility of urea and thiourea is increased, resulting in no precipitation and excellent drying resistance.
