Abstract

Ink having high adhesiveness for various substrates. The ink contains water, an organic solvent, at least one compound selected from formulae (1) and (2), and at least two kinds of resin particles. Ink-jet method. Record.

First claim

What is claimed is:

1 . An ink comprising:
water; an organic solvent; at least two kinds of resin particles; and at least one compound selected from formulae (1) and (2):

where R 1 , R 2 , and R 3 , which may be the same or different, each independently represents an alkyl group having 1 to 5 carbon atoms,

where R 4 represents a methyl group or an ethyl group, and R 5 represents a hydrogen atom, an alkyl group having 1 to 8 carbon atoms, a cycloalkyl group or an aryl group.

2 . The ink according to claim 1 , wherein the mass ratio (B/A) is 0.05 to 0.3 where A is the mass % of the resin particles present in the ink in the largest amount based on the total mass of all particles in the ink and B is the mass % of the all the resin particles present in the ink except the resin particles present in the ink in the largest amount.

3 . The ink according to claim 1 , wherein the mass ratio (S/C) of the mass content S (mass %) of the at least one compound selected from formulae (1) and (2) based on the total mass of the ink and the total solid concentration C (mass %) of the resin particles present in the ink based on the total mass of the ink is from 0.3 to 1.5.

4 . The ink according to claim 1 , wherein the at least one compound selected from formulae (1) and (2) comprises 3-methoxy-N,N-methylpropionamide.

5 . The ink according to claim 1 , wherein at least one of the at least two kinds of resin particles are polyurethane resin particles.

6 . The ink according to claim 1 , wherein two of the at least two kinds of resin particles are polyurethane resin particles and polyvinylchloride resin particles.

7 . The ink according to claim 1 , wherein the organic solvent is selected from 1,2-propane diol, 1,2-butane diol, 2,3-butane diol, 2-methyl-2,4-pentane diol, and dipropylene glycol monomethyl ether.

8 . The ink according to claim 1 , comprising at least one compound of formula (1).

9 . The ink according to claim 1 , comprising at least one compound of formula (2).

10 . An ink-jetting recording method, comprising recording an image by stimulating and discharging the ink of claim 1 .

11 . The ink-jetting recording method according to claim 8 , further comprising heating the image after the recording.

12 . A record, comprising an image formed of the ink of claim 1 .
