This invention relates to complexes of ultraviolet absorbers with quaternary ammonium compounds which are substantially free from unwanted salts. Such complexes are formed through ionic bonds formed between the two compounds. The inventive complexes are then removed of substantially all excess inorganic salt so as to obtain a UV absorber compound which exhibits improved light- and washfastness properties, which easily coats subject surfaces, which provides excellent non-fogging and non-cracking characteristics, and which also possesses anti-static, anti-microbial, and anti-abrasion properties. This invention also concerns methods of making and utilizing such inventive ultraviolet absorbing complexes.
L'invention porte sur des complexes d'absorbeurs d'UV et de composés d'ammonium quaternaire pratiquement exempts de sels non désirés formés par l'intermédiaire de liaisons ioniques reliant les deux composés. On élimine ensuite desdits complexes la quasi-totalité des sels non désirés en excès, ce qui donne un composé absorbeurs d'UV présentant une résistance améliorée à la lumière et au lavage, facile à déposer à la surface d'objets, excellent du point de vue de l'absence de voilage et de craquelage et présentant de plus des propriétés anti-statiques, anti-microbiennes et anti-abrasion. L'invention porte également sur des procédés de fabrication et d'utilisation desdits complexes.
