Let f1 and f2 be graph parameters. The Ramsey number r(f1 m; f2 ≥ n) is defined as the minimum integer N such that any graph G on N vertices, either f1(G) ≥ m or f2(Ḡ) ≥ n. A general existence condition is given and a general upper bound is shown in this paper. In addition, suppose the number of triangles in G is denoted by t(G). We verify that (1 - o(1))(24n)1/3 ≤ r(t ≥ n; t ≥ n) ≤ (1 + o(1 ))(48n)1/3 as n → ∞.
