    摘要: The present invention is directed to an ink composition resistant to solvent evaporation which may be employed for use in retractable permanent marker pens. Generally, the ink composition of the present invention comprises n-propanol, a pyrrolidone, a tryglyceride, a terpene phenolic resin, and at least one colorant to yield a detectable color when the ink composition is applied to a writable substrate. Additionally, the ink composition may further comprise at least one of polyether modified dimethylpolysiloxane copolymer and silicone glycol surfactant. Optionally, the ink composition may further comprise water.

    摘要: In general, a smear-resistant ink composition according to the present invention comprises: (1) water; (2) at least one glycol selected from the group consisting of diethylene glycol, ethylene glycol, glycerol, and propylene glycol; (3) a pyrrolidone selected from the group consisting of 2-pyrrolidone and 3-pyrrolidone; and (4) at least one colorant that produces a detectable fluorescent color when the ink composition is applied to paper. Preferably, the pyrrolidone is 2-pyrrolidone. In one preferred embodiment, the at least one glycol comprises diethylene glycol and ethylene glycol. In another preferred embodiment, the at least one glycol comprises diethylene glycol, ethylene glycol, and propylene glycol. The composition can comprise other ingredients, such as a basic color stabilizer, a resin, a resin modifier that is a carbonate salt, a biocide, and a nonionic surfactant. The colorants can be formulated to produce a pink, yellow, blue, green, purple, or orange color; other colors are possible.
