Abstract:
1. A process for producing self-dispersing, curable, epoxy resins, the process comprising: (i) reacting (a) one or more α,β-unsaturated carboxylic acid esters of the formula: wherein R 1 represents a hydrocarbon radical having up to 15 carbon atoms, wherein R 2 , R 3 , and R 4 each independently represents a substituent selected from the group consisting of hydrogen, hydrocarbon radicals having up to 20 carbon atoms, and —(CH 2 ) n —COOR 1 , wherein R 1 is as defined above and n represents a number of from 0 to 10; with (b) comprising at least one monoaminopolyalkylene oxide compound having reactive hydrogen atoms of the formula: wherein, R 8 represents a monofunctional organic group having from 1 to 12 carbon atoms, R 9 represents a polyoxyalkylene group having from 5 to 200 polyoxyalkylene units selected from the group consisting of ethylene oxide, propylene oxide and statistical or block mixtures thereof, and R 10 represents hydrogen or an aliphatic radical having from 1 to 4 carbon atoms, and wherein (a) and (b) are present in quantities such that the equivalent ratio of the reactive hydrogen atoms in (b) to the α,β C═C double bonds in (a) is from 10:1 to 1:10, to form an intermediate product Z1; and (ii) reacting the intermediate product Z1 with (c) one or more polyepoxides having a number of oxirane rings, wherein the intermediate product Z1 and the one or more polyepoxides are present in quantities such that the equivalent ratio of the oxirane rings to the reactive hydrogen atoms in (b) is from 100:1 to 1.5:1.
