Abstract
Process for the preparation of substituted 2- (2-hydroxyphenyl) -benzotriazole compounds, characterized in that a compound of 2- (2'-hydroxyphenyl) -benzotriazole containing in the 3'position an acylable amino group is reacted with an agent acylation to form a compound of the general formula I **(See formula)** in which "acyl" means an organic acyl radical, and R1 means hydrogen or an alkyl, alkenyl, cycloalkyl, or aralkyl radical, whereby R1 and "Acyl" can form a ring together with the nitrogen atom, and in this case R1 represents a carbonyl group or a methylene group optionally substituted by alkyl groups, and wherein nucleus A may be substituted at positions 4, 5, and 6, by alkyl, alkoxy, carboxy, carboxylic ester, carboxylic amide, sulfonic amide, as well as arylsulfonyl or halogen groups, and core B can be substituted at the 4'and 5' positions by hydrocarbon groups, alkoxy groups or halogens.
