UV CURABLE INKJET COMPOSITIONS FOR HIGH-DENSITY PRINT HEADS

摘要

A combination of: a) an inkjet print head having a nozzle density of at least 600 dpi and nozzles with an outer nozzle diameter D smaller than 25 µm; and b) a LJV curable inkjet composition containing 0 to 10 wt% of one or more monofunctional monomers and at least A wt% of 2-(2-vinyloxyethoxy)ethyl acrylate, wherein both wt% are based on the total weight of the UV curable inkjet composition; and wherein A is defined by the formula : 100 wt% - D x 3.0 wt%/µm = A = 100 wt% - D x 1.0 wt%/µm. An inkjet printer and an inkjet printing method are also disclosed.
