RADIATION CURABLE PHOSPHORATE ESTER COMPOUNDS Abstract of the Disclosure Radiation curable phosphorate ester compounds of the following formula: Image wherein, Rd is selected from the group consisting of Image n - 1-3, and those bond sites on Y not occupied by Rd are occupied by a moiety selected from the group consisting of -H and -ReOH wherein Re is a straight chain or branched alkyl having 1 to 20 carbon atoms; Ra is selected from -H and -CH3; -Y- is a hydrocarbon moiety selected from the group consisting of straight chain, cyclic and branched aliphatic, aromatic, and alicyclic moieties of 1-30 carbon atoms; and R is an alkylene moiety having 2 to 5 carbon atoms; Rf is selected from the group consisting of hydrogen or methyl; A is selected from the group consisting of Image which n1 is an integer from 1 to 6; and is selected from the group consisting of alkylene moieties having 2 to 10 carbon atoms, 5- or 6-membered carbocyclic aliphatic radials having 5 to 10 carbon atoms, and arylene radicals having 6 to 10 carbon atoms; and m = 1-10. These compounds are useful as dispersants in magnetic recording media, and yield media of improved stiffness.
