THE EFFECT OF PHOTOCHROMIC MATERIAL ON UV SCREEN PRINTING PHOTOCHROMIC INK’S PHOTOCHROMIC IMPACT

摘要

Both the quantity of Photochromic material and the proportion between pigment and pre-polymer seriously affect UV screen printing Photochromic ink’s photochromic impact. The inks are prepared by changing the quantity and proportion, through test the luminous intensity of ink, and the effect of Photochromic material on UV screen printing Photochromic ink’s Photochromic impact were studied. The results show the optimal quantity is 8% and the proportion is 1:6.
