<p><P>PROBLEM TO BE SOLVED: To provide a marking ink composition for an oil-adhered metal surface which can form a clear image on the oil-adhered metal surface and is rich in convenience and practicality capable of satisfying identifiability in the manufacturing process since the image is not easily removed. <P>SOLUTION: The marking ink composition for an oil-adhered metal surface comprises at least a colorant, a resin and one or more solvents selected from alcohols, glycol ethers and esters. When 10 pts.wt. of the resin and 2 pts.wt. of a fat and oil essentially consisting of a mineral oil forms a film of 40μm in thickness, the film has a light transmittance of 65% or less. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
