PROBLEM TO BE SOLVED : To provide a pigment dispersion liquid having good dispersibility of a pigment after lapse of time and capable of giving a photosensitive resin composition even after lapse of time, the composition permitting formation of a micropattern with high adhesiveness at a low exposure dose, and to provide a production method of a photosensitive resin composition using the pigment dispersion liquid.SOLUTION : The pigment dispersion liquid comprises : a pigment; a solvent; and a compound expressed by formula (1) below. In the formula, Rand Reach independently represent a hydrogen atom or an organic group, however, at least one of them represents an organic group, and Rand Rmay be bonded to form a cyclic structure and may include a bond of hetero atoms; Rrepresents a single bond or an organic group; Rto Reach independently represent a hydrogen atom, an organic group or the like, however, Rand Rare inhibited from being a hydroxyl group; and Rrepresents a hydrogen atom or an organic group.
