Abstract
Capsules containing water-dispersible material are disclosed. They are formed from an admixture of low HLB emulsifier, oily water-immiscible solvent for the emulsifier urea-formaldehyde prepolymer water-dispersible material, and water. This admixture is agitated to form a water-in-oil emulsion to which amphiphatic acidic catalyst is added to cure the prepolymer. After curing to solid form, the capsules are separated from the remaining liquid of the admixture.
