<P>PROBLEM TO BE SOLVED: To provide a silk screen ink having stable adhesiveness to a polyolefin substrate, particularly an untreated polyolefin film, having a high gloss and exhibiting excellent rub resistance and oil resistance, because conventional silk screen inks improve adhesiveness to a polyolefin substrate through a polyolefin resin such as chlorinated PP, chlorinated PE or EVA, but have problems with solubility of a binder resin in a solvent or compatibility in the case of using two or more binder resins, versatility of adhesion to various printing substrates and temporal stability of the inks, accordingly the inks cause deterioration in the gloss, rub resistance, oil resistance (animal and vegetable oils), etc., of a printed material and have practical problems. <P>SOLUTION: The silk screen ink for a polyolefin substrate includes a binder resin, a solvent and a pigment, wherein the binder resin includes a cyclized rubber and a chlorinated polyolefin. <P>COPYRIGHT: (C)2012,JPO&INPIT |
