<p>An ink composition for roll printing is provided to ensure excellent properties in which the coating fail such as the hole of the coating surface or the pigment lump is not generated, by using an acrylic copolymer resin including a fluoro group. An ink composition for roll printing comprises an acrylic copolymer resin including a fluoro group of the chemical formula 1; a polyfunctional acrylmonomer having an ethylenically unsaturated double bond; a thermal polymerization initiator; and a solvent. In the chemical formula 1, R1, R2 and R3 are independently a hydrogen atom or a methyl group; R4 is C1-C8 alkyl groups containing a fluoro group or aromatic group; as m, n and l are an integer, the rate of m / n / l based on the mole rate is 60-70 / 15-34 / 1-15. The number average molecular weight of the copolymer resin is 5,000-50,000.</p> |
