Printed media and packaging

Claims

1. A printing medium suitable for offset printing using an active energy ray curable ink containing an active energy ray curable resin, The substrate layer comprises at least an active energy ray curable resin having affinity for it. The substrate layer, when measured by micro-angle incident X-ray diffraction using a zero-dimensional detector with the 2θ method using CuKα rays, has an X-ray diffraction pattern in which the intensity of the amorphous peak is I0, the intensity of the first peak (110) plane is I1, and the intensity of the second peak (200) plane is I2, is given by the following equation (1): R = (I1+I2) / I0...(1) A printing medium having an intensity ratio R of 2 to 20, as expressed by [formula].

2. The printing medium according to claim 1, wherein the substrate layer is configured to improve adhesion with the active energy ray curable resin by irradiation with an active energy ray having an acceleration voltage of 120 kV or less and an irradiation dose of 25 to 50 kGy.

3. The printing medium according to claim 1 or 2, further comprising a modified layer for modifying the active energy ray curable resin.

4. The printing medium according to claim 3, wherein the modified layer comprises a urethane resin or an acrylic resin.

5. A package formed by the printing medium described in Claim 1 or 2.
