By means of the generalized additive generators of representable uninorms, we introduce a kind of fuzzy implications, which are called 
 
 -implications. These implications are shown to be different from the known (S, N)-, R-, QL-, generalized-
 
  and 
 
 -generated, and Yager’s 
 
 - and 
 
  -implications. Generalizations of three classical logic tautologies with implications are investigated. A series of necessary and sufficient conditions are established, under which the corresponding functional equations are satisfied.
