A photocationically-curable composition including (a) at least one divinylarene dioxide, (b) at least one cationic photoinitiator, and (c) at least one cyclic ester compound; a process for making the curable composition; and a cured product made therefrom. The cured product made from the above curable composition offers improved properties and are useful for various applications including ink formulations. 1. A process for the preparation of a photocationically-curable composition comprising admixing:a. at least one divinylarene dioxide,b. at least one reactive diluent,c. at least one cationic-photoinitiator,d. at least one vinyl ester,e. at least one cyclic ester, andf. at least one pigment.2. The process of claim 1 , wherein the at least one divinylarene dioxide is chosen from a group comprising divinylbenzene dioxide claim 1 , substituted divinylbenzene dioxide claim 1 , divinylnaphthalene dioxide claim 1 , divinylbiphenyl dioxide claim 1 , divinyl-diphenylether dioxide claim 1 , and mixtures thereof.3. The process of claim 2 , wherein the at least one divinylarene dioxide comprises divinylbenzene dioxide (DVBDO) and diisopropenylbenzene dioxide (DIBDO).4. The process of claim 3 , wherein the at least one divinylarene dioxide comprises a mixture of the 1 claim 3 ,3- and 1 claim 3 ,4-isomers.5. The process of claim 1 , wherein the reactive diluent comprises cycloaliphatic epoxides claim 1 , aliphatic epoxides claim 1 , C-Calkyl glycidyl ether claim 1 , ortho-cresylglycidyl ether claim 1 , 1 claim 1 ,4-butanediol diglycidyl ether claim 1 , 1 claim 1 ,6-hexanediol diglycidyl ether claim 1 , trimethylolpropane triglycidyl ether claim 1 , 2-ethylhexylglycidyl ether claim 1 , versatic acid glycidyl ester claim 1 , vegetable oil epoxides claim 1 , limonene dioxide claim 1 , vinylcyclohexene monoxide claim 1 , vinylcyclohexene dioxide claim 1 , styrene oxide claim 1 , and combinations thereof.6.
