摘　　要： 采用二氧化硅与塑性颜料对原纸进行预涂,并将新型抗氧剂TBM应用于热敏显色体系中,探讨了抗氧剂对热敏层防褪色性能的影响。结果表明:抗氧剂的使用可提高热敏层的饱和光密度,使涂层的反射光密度达到1.33D,同时涂层具有良好的抗水、防褪色性能,热敏层发色后浸入水中4h,颜色保留率达到98.5%。 With silica and plastic pigment Pre-coated onto the base paper, the new type antioxidant TBM was used in the temperature sensitive coloration system and the influence of antioxidant on anti-fading property of sports lottery paper was discussed. The results show that the saturated color density is improved by addition of antioxidant, and the reflection optical density reached 1.33D, the thermal coating layer has better water-resistant and anti-fading properties at the same time. the color remaining ratio is up to 98.5% when the thermal layer is immersed in water for 4 hours after the colour development.
