Patent ID: 7331665

Claim:
An inkjet recording method comprising the step of: forming a color image with respective inks of at least cyan, magenta, yellow and black on a recording medium by while scanning a recording head multiple times on a same recording area of the recording medium, forming a thinned-out image according to an thinning-out pattern without regularity in each scanning, the recording head having a plurality of nozzle sections for jetting inks, wherein a nozzle pitch of the recording head is from 10 to 50 μm, the respective inks contain pigments, at least one organic solvent with high boiling point and water, at least one of the respective inks contains a compound represented by the following general formula (I), a surface tension of the respective inks is from 30 to 50 mN/m, in the recording medium, a transferred amount at 0.04 sec of time by Bristow method is 10 ml/m 2 or more, and the recording medium has a micro-porous layer containing inorganic fine particles with a mean particle size of 15 to 100 nm and a hydrophilic binder, a printing acceptable rate of the thinning-out pattern is from 15 to 35%, and dot sizes formed by the ink jetted from the recording head are from 10 to 50 μm on the recording medium wherein R 1 to R 3 are individually selected from the group consisting of a hydrogen atom, a substituted or unsubstituted alkyl, alkenyl, aryl, acyl, heterocyclic group, NR 4 R 5 and OR 6 ; R 4 to R 6 are individually selected from the group consisting of a hydrogen atom, a substituted or unsubstituted alkyl, alkenyl, aryl, acyl, heteroaryl, heterocyclic group, NR 4 R 5 and OR 6 ; R 1 and R 2 , or R 1 and R 3 may be bound to one another to form a ring; and X represents an oxygen atom or NH.).
