    摘要: Provided are: a surface treatment liquid having a hydrophilization effect that is not easily deteriorated over time even if a surface-treated article is exposed to various agents; and a surface treatment method using the surface treatment liquid. The surface treatment liquid contains a resin (A) and a solvent (S). The resin (A) contains a constituent unit (a1) derived from a betaine monomer comprising a group having an ethylenically unsaturated double bond, a cationic group, and an anionic group, and not comprising an ester bond or an amide bond. The cationic group is preferably a quaternary nitrogen cation group, and the anionic group is preferably a sulfonic acid anion group, a phosphonic acid anion group, or a carboxylic acid anion group.

    摘要: An automatic dishwashing composition is provided, comprising: builder; nonionic surfactant; first dispersant polymer comprising: 60 to 98 wt % of structural units of formula I, wherein each R1 is independently selected from a hydrogen and a —CH3 group; and 2 to 40 wt % of structural units of formula II, wherein each R2 is independently selected from a —C1-4 alkyl group and wherein each R3 is independently selected from a hydrogen and a methyl group; and second dispersant polymer comprising: 60 to 98 wt % of structural units of formula I; wherein each R1 is independently selected from a hydrogen and a —CH3 group; and 2 to 40 wt % of structural units of formula II; wherein each R2 is independently selected from a —C1-4 alkyl group and wherein each R3 is independently selected from a hydrogen and a methyl group; wherein the first dispersant polymer and the second dispersant polymer are different.
