  • Publication number: 20220227154
    Abstract: A method of producing an image recorded material is a method including an image recording of sequentially applying a pretreatment liquid containing an aggregating agent, a first ink containing a first resin, and a second ink containing a second resin onto an impermeable base material to record an image, in which in the image recording, the image is recorded under a condition in which a ratio of a total applied mass of the first resin and the second resin per unit area to an applied mass of the aggregating agent per unit area in an overlapping region formed such that a region where the pretreatment liquid is applied, a region where the first ink is applied, and a region where the second ink is applied overlap each other in plan view is generated is 16.0 or greater and 30.0 or less.

  • Publication number: 20220143998
    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 ?total calculated by Equation (1) is 40 kgf/cm2 or less. E(Td) represents an elastic modulus of the resin X at the temperature Td, ?(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, ?r(T) represents a linear expansion coefficient of the resin X at the temperature T, and ?s(T) represents a linear expansion coefficient of the resin base material A under specific conditions.
