PROBLEM TO BE SOLVED: To provide a combination of a pair of ink-jet color ink and acceptors, which combination can generate the image in which both of the difference of gloss level between an image formed region and a non-image formed region and the difference of gloss level between various colors in a color image are concurrently minimized. SOLUTION: The material is the combination of a pair of ink-jet ink and a recording element. The material includes a porous ink-jet recording element having at least about five 60° mirror glossiness and a pair of pigment-ink-jet ink including at least two kinds of ink. In the case of a 60° reflecting angle, RGD value is smaller than 40 %, and RGV value between ink is smaller than 10 %. The RGD value and RGV value are calculated by Equation (A) and Equation (B), respectively, where I shows variables for identifying specific color patches used in the evaluation, and N shows total number of color patches used in the evaluation.
