UV-absorptiemiddelen

UV absorbers of the bis- or tris-2'-hydroxyphenyltriazine type useful in photographic materials, inks or recording materials for ink-jet printing, and surface coatings have the formula in which the radicals R1, independently of one another, are -(CH2CHR5O)n-R8, -CH2-CH(OH)-CH2-O-(CH2CHR5O) n-R8...
