Printing ink composition, method for forming near-infrared light antireflection layer on substrate surface, and near-infrared light antireflection material
2011
The invention provides a printing ink composition comprising a pigment, resin, a solvent, and an auxiliary agent. The pigment comprises pearlescent powder, titanium dioxide, extinction powder and a fluorescent brightener. An average particle size of the pearlescent powder is 8-12mum. The invention also provides a method for forming a near-infrared light antireflection layer on a substrate surface, and a near-infrared light antireflection material obtained with the method. The printing ink composition provided by the invention is white. According to the near-infrared light antireflection material obtained by printing by using the white printing ink composition provided by the invention, a visible light transmittance is 0.1-5.2%, and a near-infrared light transmittance is up to 43.6-71.4%.
