Abstract
PURPOSE: Titled ink that is made by adding pigments, a high polymer substance showing rubber elasticity in the solution state and a metal soap to a mixed solvent solution, thus being erazed with a usual erazor and enabling stable writing for a long period of time.
CONSTITUTION: (A) Pigments as a colorant, (B) a high-polymer substance showing rubber elasticity in the solution state, preferably polynorbornene, trans-1,4- polyisoprene and (C) a metal soap as a lubricant are added to (D) a mixed solvent of (a) a low boiling organic solvent that boils lower than 180°C, shows high evaporation rate and acts as a plasticizer to component B such as xylene and (b) a high boiling organic solvent that boils higher than 300°C and shows low evaporation rate such as naphthenic oil to produce the objective ink. The composition of these components is preferably 7W20pts.wt. of component A, 5W20pts. of B, less than 15pts. of C and 10W15pts. of (a) in component D and 15W35pts. of (b).
