- Abstract
In this study, a highly stable bis-triazine stilbene-type fluorescent molecule (FBs) intercalated layered double hydroxide (LDHs) composite light stabilizer (FBs-LDHs) was prepared via co-precipitation method, and its brightening performance and light-induced yellowing inhibition of paper prepared from high yield pulp were evaluated. The results showed that the LDHs could effectively inhibit the photoisomerization of FBs and improve the fluorescence performance of FBs-LDHs. After 48 h of UV aging, the PC value of FBs-LDHs coated pa‐ per was 3. 9 lower than that of uncoated paper, and 3. 0 lower than that of FBs coated paper, indicating that FBs-LDHs could better inhibit the photo-return of yellowing of highyield pulp paper.
