Claims22
An inkjet recording sheet comprising a support and, on a surface of the support, a colorant-receiving layer including at least one of a compound represented by the following general formula (1) and a compound represented by the following general formula (2) and including a vapor-phase-process silica, a polyvinyl alcohol, a boron compound, and a mordant:
- RO(CH2CH2O)nH (1)
- wherein, in the formula (1):
- R represents a saturated hydrocarbon group having from 1 to 12 carbon atoms, an unsaturated hydrocarbon group having from 1 to 12 carbon atoms, a phenyl group, or an acyl group;
- and n represents an integer of 1 to 3,
- RO(CH2CH(CH3)O)nH (2)
- and in the formula (2):
- R represents a saturated hydrocarbon group having from 1 to 12 carbon atoms, an unsaturated hydrocarbon group having from 1 to 12 carbon atoms, a phenyl group, or an acyl group;
- and n represents an integer of 1 to 3.
A method for forming a colorant-receiving layer of a n inkjet recording sheet, the method comprising the steps of:
- preparing a coating liquid that includes a vapor-phase-process silica, a polyvinyl alcohol, and at least one of a compound represented by the following general formula (1) and a compound represented by the following general formula (2):
- RO(CH2CH2O)nH (1) RO(CH2CH(CH3)O)nH (2)
- in which formulae (1) and (2), R represents a saturated hydrocarbon group having from 1 to 12 carbon atoms, an unsaturated hydrocarbon group having from 1 to 12 carbon atoms, a phenyl group, or an acyl group, and n represents an integer of 1 to 3;
- preparing a solution that includes a boron compound and a mordant;
- applying the coating liquid onto a surface of a support by using a coater;
- applying the solution onto a coating layer formed by the coating liquid at a time after commencement of the step of applying the coating solution but before a falling-drying-rate period of drying of the coating layer;
- and
- curing the coating layer.
