Abstract: A composition for forming a colored layer includes a dye, an ionizing radiation-curable resin, a photoinitiator, and a solvent. The dye contains a first colorant and a second colorant, the first colorant has a wavelength of maximum absorption in a range of 470 nm to 530 nm, and an absorption spectrum with a full width at half maximum of 15 nm to 45 nm, the second colorant has a wavelength of maximum absorption in a range of 560 nm to 620 nm, and an absorption spectrum with a full width at half maximum of 15 nm to 55 nm, and the ionizing radiation-curable resin contains a resin having an amine structure.

Abstract: A coating agent including a block copolymer capable of forming a lamellar microphase separation structure, and a liquid medium. The block copolymer includes a first block (A1) forming a non-adsorptive layer, and a second block (B1) forming a layer that is adhesive or fusible to a heat sealable substrate, the first block (A1) includes a copolymer having nitrile group-containing (meth)acrylic monomer units and alkyl group-containing (meth)acrylic monomer units, and the alkyl group-containing (meth)acrylic monomer units are included in a proportion of 0.1 mol-0.8 mol with respect to 1 mol of the nitrile group-containing (meth)acrylic monomer units.
