The invention relates to o-hydroxyphenyl-s-triazines of formula ##STR1## wherein at least one of Y and Z are C.sub.1 -C.sub.18 alkoxy The compounds are suitable for use as UV stabilisers for the photochemical and thermal stabilisation of polyester fibre materials and as stabilisers for organic ploymers.

Hydroxyphenyl-s-triazines

o-Hydroxyphenyl-s-triazines are described which contain at least two alkoxyphenyl substituents. They have the formula (1). The compounds according to the invention are suitable as stabilizers for textile fiber materials, in particular polyester fiber materials, and for organic polymers. Furthermore, they are suitable for use as sunscreens in cosmetic preparations.
