Halogen-free ultraviolet light radiation, solidification and light guiding printing ink relates to silk-screen ink for fine chemical engineering, and aims to solve the defects of low lightness, poor brightness uniformity and big chroma deviation of a conventional product. In order to solve the problems, the ink is prepared by the following components: aliphatic polyurethane acrylate low polymer, amino acrylate low polymer, acrylate monomer, light initiators, defoaming agents, defoaming agents, light guiding powder, and 3-ethyoxyl ethyl propionate. The ink and preparation and usage methods thereof have the advantages that halogen is not contained, environmental protection is achieved, the production yield is improved, backlights are enabled to be more energy saving, the chroma deviation value of the color can be reduced within 0.3%, the design of unilateral short-side light intake is adopted for a large-size LED display screen, and the energy conservation is reduced effectively.

High gloss high abrasion resistance ultra-violet curing overprinting varnish of mobile phone and preparation method thereof

Photo-curable screen printing ink and preparation method thereof

The invention relates to a baking-curable light-guide printing ink and a light-guide plate employing the printing ink. The light-guide printing ink comprises the components of: a polymer obtained by a cross-linking reaction of polymethacrylic resin and polyester acrylate and grafting reactions of light-guide powder with polymethacrylic resin and polyester acrylate respectively, and a solvent. According to the light-guide printing ink, through the chemical reactions, the light-guide powder is grafted in the polymer, such that the light-guide printing ink has a quantum optical effect, and is provided with an excellent optical performance. Also, as a result of practice, the curing temperature of the light-guide printing ink is low, and the curing temperature is below 60 DEG C. The light-guide plate employing the light-guide printing ink has extremely high light-guide uniformity and light transmittance, high optical performance, and excellent screen-printing performance.
