摘要： Provided are: a surface treatment liquid with which it is possible to conduct a surface treatment of an object to be treated, so that water, upon contact with the treated surface, rapidly spreads on and wets the surface; a surface treatment method for treating an object using the surface treatment liquid; and a method for producing a roll-shaped sheet which has been surface-treated by the surface treatment method. The surface treatment liquid comprises a polymer (A) and a solvent (S), wherein the polymer (A) comprises a constituent unit (a1) which is derived from a monomer having a log P value of 0.5 or less and which has a hydrophilic group and a constituent unit (a2) derived from a monomer that gives a homopolymer having a glass transition temperature (Tg) of 120° C. or higher, and the polymer (A) has a weight-average molecular weight of 500-20,000.

摘要： An object is to provide a surface treatment liquid which can firmly bond, while coating the surface of a treatment target with an extremely thin film, a coating whose hydrophilicity is unlikely to be lowered even when the coating is brought into contact with fats and the like to the surface of the treatment target and a surface treatment method using the surface treatment liquid described above. In a surface treatment liquid containing a resin (A) and a solvent (S), as the resin (A), a resin is used which includes a constituent unit (a1) that includes an organic group including a quaternary ammonium cation group and having a sulfonic acid anion group at a terminal and that is derived from an N-substituted (meth) acrylamide, and includes a reactive silyl group in at least one of molecular chain terminals, the concentration of the resin (A) in the surface treatment liquid is less than 2 mass % and the pH of the surface treatment liquid is 4 or less.
