Abstract
The invention relates to gloss oil for IMD (In-Mold Decoration) printing ink, IMD printing ink, an IMD film and a preparation method of the gloss oil. The gloss oil for IMD printing ink consists of the following components by weight percent: 25-30% of cyclohexanone, 15-20% of isophorone, 15-20% of trimethylbenzene, 15-20% of Shenzhen PuRuiSen polyester resin ES-300 and 25-30% of Shenzhen PuRuiSen polyester resin ES-410. The preparation method of the gloss oil comprises the following steps: adding the cyclohexanone, isophorone and trimethylbenzene in a blender, turning on the blender, adding the polyester resin ES-300 and the polyester resin ES-410 during stirring, and stirring uniformly. Compared with the prior art, the invention has the advantages that the IMD film printed with the IMD printing ink prepared from the gloss oil provided by the invention does not deform during high-temperature injection, and the adhesion of the printing ink is good; and the curing agent prepared from 70% of 1,6-diisocyanatohexane and 30% of toluene diisocyanate can ensure the yellowing resistance and enhance the hardness of the printing ink at the same time.
