Abstract
PURPOSE: A composition for easily erasing a drawing ink handwriting on a drawing film, which is prepared, by mixing an adsorptive powder, which has adsorbed a composition miscible with the drawing ink.
CONSTITUTION: An erasing composition, comprising an adsorptive powder, which has adsorbed about 1/2pt.wt. of an erasing liquid, miscible with a drawing ink. The erasing liquid is suitably selected from ethylene glycol, an oil-soluble surfactant, i,e., a higher alcohol sulfate, etc., depending on whether the drawing ink in water- soluble, alcohol-soluble or oil-soluble. The adsorptive powder is Aerosil (fine silica gel), zeolite, etc. Aerosil of particle size 20W50mμ is allowed to adsorb about 1/2pt.wt. of the erasing liquid and then used after being crushed to 300 mesh or lower. Zeolite of particle size ≤1μ, is used after adsorption and crushing to 300 mesh or lower.
