A curing agent for epoxy resins having improved solubility characteristics has the formula ##STR1## where R is --CH 2 C 6 H 4 X or --CH 2 CH 2 C 6 H 4 X, n and X is either --H, --CH 3 , --OCH 3 , --OH, or --NY, n and where Y is --H or CH 3 . n Such substituted cyanoguanidines are soluble in various solvents and do not require the use of undesirable solvents necessary with cyanoguanidine (dicyanodiamide) itself. |
