Para-dialkylaminobenzoic acid esters of the formula:
Where R is methyl or ethyl and n= 1 or 2 are described. These compounds are potent photoactivators especially for photoinitiators of the substituted thioxanthone type. All the compounds of the invention are liquids at temperature down to O°C thus markedly facilitating compounding. Rapidly curing photocurable compositions e.g. film of TiO2 pigmented photocurable resins can be formulated such as can be used as or in printing inks.
式中的对二烷基氨基苯甲酸酯:
其中 R 为甲基或乙基,n= 1 或 2。这些化合物是强效光活化剂,尤其适用于取代的硫杂蒽酮类型的光引发剂。本发明的所有化合物在低至 O°C 的温度下均为液体,从而大大方便了配制。可配制出快速固化的光固化组合物,如 TiO2 颜料光固化树脂薄膜,可用作印刷油墨或在印刷油墨中使用。
