    摘要: The invention relates to an improved process for the manufacture of bis-resorcinyl triazines of formula (I) wherein R
    1 is a C
    1 C
    18 alkyl group or C
    2 -C
    18 alkenyl group as well as the respective alkyl substituted bis-resorcinyl derivatives of formula (II) wherein R
    1 is a C
    1 -C
    18 alkyl group or C
    2 -C
    18 alkenyl group and R
    2 and R
    3 are independently of each other a C
    1 -C
    18 alkyl group or a C
    2 -C
    18 alkenyl group.
