Pigment-dispersed aqueous recording liquid and printed material
First Claim
1. A pigment-dispersed aqueous recording liquid containing at least a pigment and resin, which comprises from 60 to 200 parts by weight of the resin to 100 parts by weight of the pigment, wherein at least one of the resin is a water-dispersible urethane based resin having an acid value of 50 to 200 mgKOH/g, and a weight fraction of a polyurethane urea part of which is at most 2.0 wt % to the urethane based resin, and the pigment dispersed in the recording liquid has a dispersion particle size D50 of from 40 to 100 nm, and wherein the water-dispersible urethane based resin is derived from a polyether diol.
