Conflict-free coloring is a kind of vertex coloring of hypergraphs requiring each hyperedge to have a color which appears only on one vertex. More generally, for a positive integer k there are k-conflict-free colorings (k-CF-colorings for short) and k-strong-conflict-free colorings (k-SCF-colorings for short). Let H n be the hypergraph of which the vertex-set is V n={1, 2,…, n} and the hyperedge-set E n is the set of all (non-empty) subsets of V n consisting of consecutive elements of V n. Firstly, we study the k-SCF-coloring of H n, give the exact k-SCF-coloring chromatic number of H n for k= 2, 3, and present upper and lower bounds of the k-SCF-coloring chromatic number of H n for all k. Secondly, we give the exact k-CF-coloring chromatic number of H n for all k.
