摘　　要：分析了影响聚对苯二甲酸乙二酯(PET)膜激光打印效果的因素并对PET膜彩色激光打印涂层配方进行了优化。研究表明:水性丙烯酸树脂涂层具有良好的图文附着力和较好耐温性;添加钛白粉有助于提高涂层耐温性和改善图像质量;通过添加防静电剂来降低薄膜电阻率,可明显改善图文打印质量,避免了图文拖尾现象。实验范围内,最适用的白色激光打印涂层配方是:水性丙烯酸树脂、白色色浆、高分子防静电剂的质量分数分别为72.11%,24.04%,3.85%。制备的涂层图文附着力为100%,图像无斑点,清晰度优良,满足PET膜激光打印应用要求。This article provides an overview of the factors that impact the laser printing effect along with optimization for formula of color laser printing coating on polyethylene terephthalate（PET） film. The results of the research show that the water-soluble acrylic resin is good at graphic adhesion and temperature resistance. The addition of titanium dioxide helps to improve the temperature resistance of coating as well as the image quality. In addition, adding antistatic agent to reduce the resistivity of thin film can obviously improve the image definition and avoid the graphic tailing phenomenon. The optimal formulation of coating for white laser printing is that the mass fractions of macromolecule antistatic agent, water-soluble acrylic resin, and white color paste are 3.85%, 72.11% and 24.04% respectively. The graphic adhesion of the coating prepared by use of the formula reaches 100%. There is no spot and good definition for the image printed, which meet the requirements of laser printing on PET film.
