    Abstract: An image recording method includes a step of preparing a first ink containing water and at least one selected from the group consisting of a chromatic colorant and a black colorant, a step of preparing a second ink containing a white colorant and water, an applying step of applying each of the first ink and the second ink onto a resin base material by an ink jet method, and a drying step of including irradiating the first ink and the second ink applied onto the resin base material with microwaves.

    Abstract: Provided is an image recording method including applying a pretreatment liquid containing water and a resin X and an ink containing water and a colorant onto a resin base material A which has a specific distortion rate and to which a tension is applied, to obtain an image, heating the image to a temperature Td and drying the image, and cooling the image to a temperature Tr, in which σtotal calculated by Equation (1) is 40 kgf/cm2 or less. E(Td) represents an elastic modulus of the resin X at the temperature Td, ε(Td) represents an expansion coefficient of the resin base material A under specific conditions, E(T) represents an elastic modulus of the resin X at a temperature T of the image in the cooling, αr(T) represents a linear expansion coefficient of the resin X at the temperature T, and αs(T) represents a linear expansion coefficient of the resin base material A under specific conditions. σ total =  σ dry + σ cool  Equation ⁢ ⁢ ( 1 ) σ dry = E ⁡ ( T d ) ⁢ ⁢ ɛ ⁢ ⁢ ( T d ) Equation ⁢ ⁢ ( 2 ) σ cool = ∫ T r T d ⁢ E ⁡ ( T ) ⁢ ( α r ⁡ ( T ) - α s ⁡ ( T ) ) ⁢ dT Equation ⁢ ⁢ ( 3 )

    Abstract: An image recording method includes determining whether a surface energy of a base material is less than 50 mN/m or greater than 50 mN/m; deciding a condition for drying a pretreatment liquid containing water and an aggregating agent as a condition A in which the mass ratio of the mass of the pretreatment liquid after being dried to the mass of the pretreatment liquid before being dried is 30% or greater and deciding a condition for drying the pretreatment liquid as a condition B in which the mass ratio thereof is less than 50% in a case where the surface energy is determined to be less than 50 mN/m and 50 mN/m or greater, respectively; applying the pretreatment liquid to the base material; drying the applied pretreatment liquid under the drying condition decided; and applying an ink containing water and a colorant to at least a part of the base material.
