Abstract
To provide a recording medium in which the ink absorbability and the color development properties of an image to be obtained are high and in which cracking in an ink receiving layer is sufficiently suppressed. A recording medium contains a base material and an ink receiving layer containing inorganic particles and a binder, in which the inorganic particles have an organosilicon structure having a quaternary ammonium group, an imino group or a substituted imino group, and a hydroxyl group.
Claims5
A recording medium comprising:
- a base material;
- and
- an ink receiving layer containing inorganic particles and a binder,
- wherein the inorganic particles have an organosilicon structure having silicon;
- a quaternary ammonium group,
- an imino group or a substituted imino group, and
- a hydroxyl group,
- wherein the organosilicon structure has the silicon, the quaternary ammonium group, and the hydroxyl group, from a side close to the inorganic particles, in an order of the silicon, the hydroxyl group, and the quaternary ammonium group.
A silane coupling agent, which is used for a recording medium having a base material and an ink receiving layer containing inorganic particles and a binder and which has a structure represented by General Formula (1)′,
- wherein, in General Formula (1)′, R1 is an alkyl group or an aryl group having 1 to 8 carbon atoms, X represents a structure represented by General Formula X, Y represents a hydrolyzable group, and a is 1, 2, or 3,
- wherein, in General Formula X, Rx1 and Rx2 each independently represent an alkylene group or an arylene group having 2 to 8 carbon atoms, at least one selected from Rx3, Rx4, and Rx5 represents a structure represented by General Formula Q and other elements represent a hydrogen atom or an alkyl group or an aryl group having 1 to 8 carbon atoms, and b is an integer of 0 to 5,
- wherein, in General Formula Q, RQ1, RQ2, and RQ3 each independently represent an alkyl group or an aryl group having 1 to 10 carbon atoms.
