| titleOfInvention | Photochromic ink prepolymer and preparation method thereof as well as photochromic ink |
| abstract | The invention provides a photochromic ink prepolymer which is prepared by polymerizing the product which is obtained by reacting a novolac epoxy resin with acrylic acid with tetrahydrobenzene anhydride. In addition, a preparation method of the photochromic ink prepolymer as well as a photochromic ink prepared by use of the prepolymer are provided. The photochromic ink is good in printing adaptability, has an obvious color changing contrast after light sensitization, and has a good economic value and higher social benefit. |
