Abstract
A recording liquid to be attached in a droplet state to an object for the purpose of recording on the object is disclosed, which contains at least one alkylene glycol selected from 1,2-pentanediol, 1,2-hexanediol and 1,3-hexanediol, thereby adjusting a zero second dynamic surface tension thereof at 35 mN/m or more and not more than 40 mN/m and contains a surfactant, thereby adjusting a static surface tension thereof which is satisfied with the following numerical expression (1):(γdst0−3)≦γsst≦(γdst0−1) (1)wherein γdst0 [mN/m] represents a zero second dynamic surface tension; and γsst [mN/m] represents a static surface tension.
