Image recording method, image recorded material, ink set, and laminate and production method thereof

An image recorded material comprising:

• an impermeable base material;
• and
• an image recorded on the impermeable base material,
• wherein the image includes a white ink layer in contact with the impermeable base material and containing a white pigment and a colored ink layer in contact with the white ink layer and containing a colored pigment other than the white pigment and has a region where the white ink layer and the colored ink layer overlap each other in plan view, and
• a mass of the white pigment per unit area in the white ink layer is 0.4 g/m2 or greater.

An image recorded material comprising:

• an impermeable base material;
• and
• an image recorded on the impermeable base material,
• wherein the image includes a pretreatment liquid layer in contact with the impermeable base material and containing an aggregating agent, a white ink layer in contact with the pretreatment liquid layer and containing a white pigment, and a colored ink layer in contact with the white ink layer and containing a colored pigment other than the white pigment and has a region where the pretreatment liquid layer, the white ink layer, and the colored ink layer overlap each other in plan view, and
• a mass of the white pigment per unit area in the white ink layer is 0.4 g/m2 or greater.

An ink set comprising:

• a white ink that contains a white pigment, a pigment dispersant, an organic solvent, and water;
• and
• a colored ink that contains a colored pigment other than the white pigment, an organic solvent, and water,
• wherein the pigment dispersant is a polymer having a crosslinked structure or a block polymer, and
• a weighted average value of solubility parameters of the organic solvents contained in each of the white ink and the colored ink is 28 MPa1/2 or less.

An ink set comprising:

• a white ink that contains a white pigment, a pigment dispersant, an organic solvent, and water;
• and
• a colored ink that contains a colored pigment other than the white pigment and water,
• wherein the pigment dispersant is a polymer having a crosslinked structure or a block polymer, and
• the organic solvent includes at least one kind of alkylene glycol having a boiling point of 120° C. to 200° C. and at least one kind of alkylene glycol alkyl ether having a boiling point of 120° C. to 200° C.
