与える筆記具用インキ組成物に関するものである。Detailed Description of the Invention [Field of Industrial Application] The present invention utilizes an existing color film that can thermally transfer color only to drawn lines that have been dry-copied. The present invention relates to an ink composition for writing instruments that provides the drawn lines that can be thermally transferred.
乾式コピーした描線にのみ、色が熱転写できるカラーフ
ィルムは、現在市販されており、それは、黒もしくは他
の色で乾式コピーされた描線を異なる色に変換できるも
のである。There are currently commercially available color films that can thermally transfer color only to dry-copied lines, which can convert dry-copied lines of black or other colors to a different color.
しかし、筆記描線は乾式コピーしなければ色の転写がで

の色に変換できるものである。The color film to which color can be thermally transferred is a colorless transparent base film coated with a composition containing a colored pigment, a white pigment, and a binder resin. When this color film is placed on the dry-copied lines and heated from above using a heating medium, the binder resin of the copied lines melts and has adhesive properties, and this shows affinity with the film-coated surface, so both are bonded. is adhered and the coated surface is peeled off from the Heath film. At this time, the white pigment hides the dry copy lines and the colored pigments are used to color the lines, so that the color can be converted to any desired color.
しかし、現在の市販の筆記具ではこのカラーフィルムが
着色できる描線を提供するものはない。However, none of the current commercially available writing instruments provide lines that can be colored by this color film.

件となることに想到し、本発明を完成させた。As a result of extensive research, the present inventor has discovered that in order to enable the mechanism of thermal transfer color film for dry copying lines to be applied to written lines, a large amount of resin for the drawn lines must exist on the paper surface, and that a predetermined amount of resin must be present on the paper surface. The present invention was completed based on the idea that the resin content of the drawn lines should melt in a temperature range and have adhesive properties, that the drawn line coating should have appropriate strength, and that it should show affinity with the coated surface.

℃ to 200℃ is used. Heat distortion temperature (18
, 6kg/cJ) or less than 70°C, it is undesirable as it may soften even in natural environments and cause horizontal lines or stickiness, and it is less strong due to residual heat after thermal transfer, making it difficult to peel off the coated surface from the film. Kui. Heat distortion temperature (18,6
kg/cd) is higher than 200℃, the temperature of the existing heating element (for example, a household iron) will not rise to that temperature,
The resin part of the drawn line does not melt and cannot be transferred.

出が困難となり、紙面に描線を書くことができない。The amount of resin added is 20% by weight to 50% by weight based on the total amount of ink.
It is used in an amount of 25% to 45% by weight, preferably 25% to 45% by weight. When the resin content is less than 20% by weight, the resin permeates into the paper surface to a large extent, and the amount and thickness of the resin remaining on the drawn line is small, resulting in insufficient adhesive strength, so that it does not adhere to the coated surface of the film and cannot be thermally transferred. Furthermore, if the resin content exceeds 50% by weight, the viscosity of the ink itself becomes too high, making it difficult for the ink to flow out from the writing instrument, making it impossible to draw lines on paper.
上記樹脂はインキ中では溶液、もしくはエマルジョンの
形態で用いられる。特にエマルジョンは高樹脂濃度、低
粘度の点で有利である。The above resin is used in the form of a solution or an emulsion in the ink. In particular, emulsions are advantageous in terms of high resin concentration and low viscosity.

相性の良いものを選択することが望ましい。In the ink formulation, colorants such as dyes and pigments can be used as necessary. Known and commercially available dyes and pigments can be used, but it is desirable to select dyes and pigments that are compatible with and do not react with the resin.
