摘要： Disclosed is a coating material for a coating layer of an injection mold, the coating material including 100 parts by weight of a resin composition and about 30 to 40 parts by weight of a curing agent. The resin composition includes an amount of about 40 to 50 wt % of a first acrylic resin, an amount of about 5 to 15 wt % of a second acrylic resin having a weight average molecular weight less than a weight average molecular weight of the first acrylic resin, an amount of about 10 to 15 wt % of a carbon component, an amount of about 0.5 to 2 wt % of a matting agent, an amount of about 0.1 to 0.3 wt % of a catalyst and an amount of about 20 to 35 wt % of a solvent, all the wt % are based on the total weight of the resin composition.
