Description
본 발명은 마커펜용 백색 잉크 조성물에 관한 것으로, 특히 냄새가 적고 말림성이 좋아 손에 묻었을 시 쉽게 떨어져 남아 있지 않으며 은폐력과 색상선명도가 크게 증가되는 등의 물성이 우수한 마커펜용 백색 잉크 조성물에 관한 것이다.The present invention relates to a white ink composition for a marker pen, and more particularly, to a white ink composition for a marker pen having a low odor and a good curling property that does not easily fall off when buried in the hand, and has excellent hiding power and color sharpness. .
일반적으로 학교, 학원, 회사 등의 강의실 등에서 오랫동안 사용되어온 분필은 다량의 분필가루를 발생시켜 실내 환경 및 인체에 유해를 가하는 정도가 컸기 때문에, 다양한 색상의 잉크용액을 사용하여 보드 등에 대한 필기 등을 가능하게 하고 지울 수 있도록 한 마커펜이 개발되어 사용되고 있음이 주지된 사실이다. 이처럼 분필을 대신하여 필기 등을 가능하게 하는 마커펜용 잉크 조성물은 현재 다수가 개발되어 개시된 상태에 있다. 그러나 기존의 마카펜용 잉크 조성물은 짙은색의 보드에 사용될 경우 그 보드에 대한 은폐력과 색상선명도가 낮아 눈에 잘 띄지 않는 즉, 노출성이 약하다는 문제가 있고, 필기된 내용을 손으로 지우는 등의 행위로 손에 묻었을 시에 쉽게 지워지지 않는다는 문제가 있다.In general, chalk, which has been used for a long time in classrooms such as schools, academies, and companies, generates a large amount of chalk powder, which is very harmful to the indoor environment and the human body. It is well known that marker pens have been developed and used to enable and delete them. Thus, a large number of ink compositions for marker pens that enable writing and the like in place of chalk are currently in a state of being developed and disclosed. However, when the ink composition for the maca pen is used on a dark board, there is a problem in that it is inconspicuous, that is, it is weakly exposed because of low hiding power and color sharpness of the board, and erases handwritten contents. There is a problem that it is not easily erased when put on the hand by an act.
따라서 본 발명의 목적은 이와 같은 문제점을 해결하기 위한 것으로, 냄새가 적고 말림성이 좋아 손에 묻었을 시 쉽게 떨어져 남아 있지 않음과 아울러 특히 은폐력과 색상선명도가 크게 증가되는 등의 물성이 우수한 마커펜용 백색 잉크 조성물을 제공하는데 있다.Accordingly, an object of the present invention is to solve such a problem, and has a low smell and good curling properties so that it does not easily fall off when it is buried in the hand, and particularly has excellent physical properties such as high hiding power and color sharpness. It is to provide an ink composition.
