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.
