Title (EN) LIGHT COLOR ROSIN ESTER COMPOSITIONS AND METHODS OF MAKING SAME
(FR) COMPOSITIONS D'ESTER DE COLOPHANE DE COULEUR CLAIRE ET LEURS PROCÉDÉS DE PRÉPARATION
Abstract:
(EN) A light color or a low color rosin or a rosin ester composition is disclosed. Significant color improvement can be obtained for a low color rosin, or a rosin ester by using a co-catalyst. In one embodiment, the co-catalyst has a triplet formation quantum yield (ɸT) of greater than 0.5 and a triplet lifetime (τT) of greater than 0.5 microseconds. In another embodiment, the co-catalyst is selected from acridone, anthrone, 9-fluorenone, thioxanthone, xanthone, derivatives, or combinations thereof.
(FR) L'invention concerne une composition de colophane de couleur claire ou faiblement colorée ou d'ester de colophane. Une amélioration notable de la couleur peut être obtenue pour une colophane faiblement colorée ou un ester de colophane à l'aide d'un co-catalyseur. Selon un mode de réalisation, le co-catalyseur présente un rendement quantique de formation de triplet (ɸT) supérieur à 0,5 et une durée de vie de triplet (τT) supérieure à 0,5 microseconde. Selon un autre mode de réalisation, le co-catalyseur est choisi parmi l'acridone, l'anthrone, la 9-fluorénone, la thioxanthone, la xanthone, des dérivés ou des combinaisons de ces derniers.
