Abstract: Esters of arylacetic acids, more particularly lower alcohol esters of arylacetic acids, including those substituted on the methylene group, are prepared by rearrangement of the corresponding alpha-halo-alkylarylketones with Ag compounds in lower alcohols and in an acid medium. From the alkyl esters so prepared, their respective free acids can be obtained, if desired, by various means such as hydrolysis or the shift with mineral acids of the alkaline salts prepared by reaction with alkali, etc.

Abstract: The present invention concerns a new class of pigments derived from cumarin and, more particularly, of bis-iminocumarinic and bis-cumarinic pigments having the following formula I described hereinlater. The present invention also includes novel processes for making the cumarinic pigments of the invention. Also, the invention relates to the use of the novel pigments of the invention for the preparation of paints, storing enamels, inks and pastes for the printing of fabrics. Also, included in this invention is the dyeing of plastic materials with the novel cumarinic pigments.
