Definitions
- the present invention relates to a UV absorber which comprises a finely divided polymer, a process for its production and its use.
- UV absorbers hereinafter also UV stabilizers.
- Substances used as UV stabilizers should be distributed as finely as possible in the application media in order to develop an even protective effect. Fine distribution in transparent media is particularly important, as otherwise incident light is scattered.
- the substance is molecularly soluble in the application medium and thus “distributed” as best as possible, this is often associated with an unfavorable migration behavior and the substance emerges from the material relatively easily. This phenomenon is called "exudation”.
- Cosmetic formulations use UV absorbers to protect human skin from the harmful effects of natural UV radiation. Soluble UV absorbers can diffuse through the skin to an undesirable degree. Pigmentary UV absorbers such as titanium dioxide or zinc oxide have the disadvantage that they scatter the incident light back white, which can lead to an undesirable, visible white light stabilizer film, especially with dark pigmented skin.
- No. 3,230,196 describes polybenzoxazoles and a process for their preparation by condensation of aminohydroxybenzoic acids or of bis (o-aminophenols) with aromatic dicarboxylic acids. These polymers should also be usable as UV absorbers. However, the document does not specify how the polybenzoxazoles are to be prepared for use as UV absorbers.
