Patent ID: 8083339

Claim:
An ink set, comprising: a recording liquid which comprises a coloring material; and a treating liquid which comprises a component reactive with a component other than coloring material in the recording liquid and which has a surface tension γ in a range expressed by 10 mN/m≦γ≦60 mN/m, wherein the recording liquid comprises a component reactive with a component in the treating liquid, and wherein a record part formed by applying the treating liquid and the recording liquid to a record medium comprises a first layer formed of the recording liquid and a second layer formed of the treating liquid, said first layer and second layer forming layer regions disposed with at least the first layer disposed on and covering the second layer, and said first layer and second layer retaining respectively therein color aggregates and fine particle aggregates, and a surface tension γ1 of the treating liquid is smaller than a surface tension γ2 of the recording liquid.
