Abstract
Official abstract text for this publication.
An ink jet composition according to the present disclosure contains a plurality of metal particles, a hydrophobic phosphorus surface treatment agent, a polyoxyalkyleneamine compound, and a solvent. The amount of the contained polyoxyalkyleneamine compound is 0.5 parts by mass to 50 parts by mass per 100 parts by mass of the metal particles.
First claim
Opening claim text (preview).
What is claimed is: 1 . An ink jet composition containing: a plurality of metal particles; a hydrophobic phosphorus surface treatment agent; a polyoxyalkyleneamine compound; and a solvent, wherein the amount of the contained polyoxyalkyleneamine compound is 0.5 parts by mass to 50 parts by mass per 100 parts by mass of the metal particles. 2 . The ink jet composition according to claim 1 , wherein the polyoxyalkyleneamine compound is at least one selected from the group consisting of a compound represented by the following formula (1), a salt thereof, a compound represented by the following formula (2), and a slat thereof: where R is a hydrogen atom or an alkyl group containing three or less carbon atoms, x is an integer of 10 or more, and a plurality of types of oxyalkylene units different in condition of R may be present in Formula (1) and where R1, R2, and R3 are independently an alkyl group containing three or less carbon atoms and n is an integer of 10 or more. 3 . The ink jet composition according to claim 1 , wherein the metal particles are made of aluminium or an aluminium alloy. 4 . The ink jet composition according to claim 1 , wherein the volume-average size of the metal particles is 0.20 μm to 1.00 μm. 5 . The ink jet composition according to claim 1 , wherein the metal particles have a flake shape. 6 . The ink jet composition according to claim 5 , wherein the average thickness of the metal particles is 10 nm to 90 nm. 7 . The ink jet composition according to claim 1 , wherein the hydrophobic phosphorus surface treatment agent is a fluorinated phosphorus compound.
