Claims45
An ink-jet recording material which comprises a water resistant support, and a porous ink-receptive layer containing inorganic fine particles having an average particle size of primary particles of 30 nm or less provided on the support, wherein said ink-jet recording material contains at least one hydrazine compound which is represented by the formula (1):
- wherein R1 to R4 each independently represents a hydrogen atom, a substituted or unsubstituted aliphatic group, an aromatic group, a heterocyclic group, a carbonyl group, a sulfonyl group, a sulfoxy group, a phosphoryl group, or an iminomethylene group, each of which may be bonded to form a ring, or may form a polymer.
An ink-jet recording material which comprises a water resistant support, and a porous ink-receptive layer containing inorganic fine particles having an average particle size of primary particles of 30 nm or less provided on the support, wherein said ink-jet recording material contains at least one hydrazine compound and said ink-jet recording material further contains a dicyane diamide resin.
An ink-jet recording material which comprises a water resistant support, and a porous ink-receptive layer containing inorganic fine particles having an average particle size of primary particles of 30 nm or less provided on the support, wherein said ink-jet recording material contains at least one hydrazine compound in an amount of 0.1 to 50 mmol/m2 and which is represented by the formula (1):
- wherein R1 to R4 each independently represents a hydrogen atom, a substituted or unsubstituted aliphatic group, an aromatic group, a heterocyclic group, a carbonyl group, a sulfonyl group, a sulfoxy group, a phosphoryl group, or an iminomethylene group, each of which may be bonded to form a ring, or may form a polymer.
An ink-jet recording material which comprises a water resistant support, and a porous ink-receptive layer containing inorganic fine particles having an average particle size of primary particles of 30 nm or less provided on the support, wherein said ink-jet recording material contains at least one hydrazine compound and wherein said ink-jet recording material further contains a thioether compound which is represented by the formula (5):
- R5—(S—R7)m—S—R6 (5)
- wherein R5 and R6 may be the same or different from each other and each represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a group containing these alkyl group and the aryl group, or may form a ring by binding to each other, provided that at least one of R5 and R6 is an alkyl group substituted by a hydrophilic group selected from a hydroxy group, a sulfo group, a carboxy group and a (poly)ethyleneoxy group, or a group containing a basic nitrogen atom selected from an amino group, an amide group, an ammonium group, a nitrogen-containing heterocyclic group, an aminocarbonyl group and an aminosulfonyl group, or a group containing at least one of the above-mentioned these groups, and the substituted alkyl group may be bonded to the sulfur atom of the thioether through a divalent linking group;
- R7 represents a substituted or unsubstituted alkylene group which may have an oxygen atom;
- and m is an integer of 0 to 10, and when m is 1 or more, at least one of the sulfur atom bonded to R7 may be a sulfonyl group.
