Abstract: A pretreatment liquid is a pretreatment liquid to be used for a pretreatment that is performed on an impermeable base material before an image is recorded on the impermeable base material, containing an aggregating agent, an aqueous medium, and a resin, in which the resin has at least one selected from the group consisting of a structural unit (1), a structural unit (2), and a structural unit (3), and a glass transition temperature of the resin is −40° C. or higher and lower than 100° C. In the formulae, R2 represents a hydrogen atom or a C1 to C4 alkyl group, A2 represents —NH— or —N(L4-Y4)—, L2 and L4 represent a divalent group or a single bond, L3 represents a divalent group, Y2 and Y4 represent a monovalent group such as an alkyl group, and Y3 represents a monovalent group such as —OH.

In the formulae, R2 represents a hydrogen atom or a C1 to C4 alkyl group, A2 represents —NH— or —N(L4-Y4)—, L2 and L4 represent a divalent group or a single bond, L3 represents a divalent group, Y2 and Y4 represent a monovalent group such as an alkyl group, and Y3 represents a monovalent group such as —OH.
