ABSTRACT:
When something is written on the nonabsorbent surface of an iron plate, a glass plate or the like with a conventional marking pen ink using ethanol, the fixing power of the handwriting is weak, whitening phenomenon occurs owing to hygroscopicity, and ink scratch takes place as a result of the clogging of a penpoint. The present invention provides an alcoholic marking pen ink composition not having such drawbacks.
The ink composition of the present invention is characterized by comprising a colorant, ethanol, an ethanol-soluble phenolic resin having a softening point of 60.degree. to 100.degree. C. or its derivative, and an ethanol-soluble ketone resin having a softening point of 60.degree. to 100.degree. C.
