(57) [Summary] [Structure] A novel UV absorber of the bis- or tris-2'-hydroxyphenyltriazine type having the formula (I): (In the formula, R 1 : independently of each other, R 2: H, OH, C 1 ~C 12 alkyl, F, Cl; R 3: H, OR 9 , C 1 -C 12 alkyl, F, Cl; R 4 : H, O R 9, C 1 ~C 12 alkyl, F, when Cl or R 2 = OH, OR 1; R 5: H, CH 3; R 6: H, C 1 ~C 16 Alkyl; R 7: C 1 ~C 14 alkyl, phenyl; R 8: H, C 1 ~ C 14 alkyl, phenyl, C 1 -C 4 alkylphenyl; R 9: C 1 ~C 4 alkyl; 1: 0 number; 0: 1 number). [Effect] Increasing the stability of magenta, cyan and yellow layers by incorporation into photographic materials, stabilizing light in inkjet printing inks and recording materials, and stabilizing surface coatings or organic materials (especially automotive paints). It is useful. |
