Suitable surface-active derivatives are urea-formaldehyde and melamine-formaldehyde precondensates which are substituted by both hydrophobic and hydrophilic groups and curable ethers of methylol ureas and methylolmelamines, many examples of which are described. Suitable aminoplast precondensates are dimethylolmelamines, hexamethylolmelamines, unetherified methylolmelmine and methylol ureas and methylolmelamines etherified with alcohols having at most 3 carbon atoms. Examples relate to the encapsulation of petroleum (to give a solid fuel), dibutyl phthalate (to give a lubricant), crystal violet lactone (for use in "carbonless" copying paper), red dye in paraffin oil (for a red copying paper) and an azo pigment.
