There is stably provided a hydrophilic cured product, such as a single-layer film, in which anionic hydrophilic groups are concentrated at a surface that is in contact with the air and which is excellent in transparency and adhesion to a substrate and tends to be rarely cracked. The hydrophilic cured product or single-layer film comprising a resin composition is produced by applying a mixture containing a polyvalent monomer (II) having two or more (meth) acryloyl groups and a compound (IV) having a specific group and a sulfonic acid group to a substrate or the like, drying the mixture if necessary, and then performing polymerization.



Ink set, recording method, recording apparatus, and recording material

An ink set includes a first ink composition, and a second ink composition, in which the first ink composition contains a first pigment, and an alkyl diol having carbon atoms of 6 or less and a normal boiling point of 240° C. or more, the second ink composition contains a second pigment, and the alkyl diol, in the first ink composition, a content of the first pigment is 2.5% by weight or more, and a content of the alkyl diol is 3% by weight to 15% by weight, in the second ink composition, a content of the second pigment is less than 2.5% by weight, and the content of the alkyl diol is 8% by weight to 30% by weight, and the content of the alkyl diol in the second ink composition is greater than the content of the alkyl diol in the first ink composition.
