Measurement method:
Spectrum separation SFF
Spectrum separation SSF is measurement whether characterization jetted ink tinctorial property is excellent, because it is considered and light
Absorb related property (such as maximum absorption wavelength λ max, absorption spectra shape and the absorbance value at λ max) and with point
Dissipate quality and the related property of stability.
By using the ink solutions of record spectroscopic data and compare maximum absorbance and extinction under reference wavelength
Degree, to calculate the spectrum separation SSF of ink.Reference wavelength depends on the pigment used.Pigment is diluted to 0.002 with water
Or 0.005% mass concentration.
Using ShimadzuUV-2101PC double-beam spectrophotometer with transmission measurement absorbance.
Jetted ink tinctorial property is characterized by the loss late after SSF and heat treatment.
Meanwhile dispersion stabilization is evaluated by comparing heat treatment (at 50 DEG C of baking temperature, one week).
As it can be seen that the mill base stability of the application and dispersibility are better than embodiment, this is mainly reflected in the amide in polyurethane
Key suction anchors schedule the surface of solid particle, and the solid particles surface of cohesion is made to be easy to wet；It is formed on the surface of solid particle
Adsorption layer increases the charge of solid particles surface, improves the intergranular reaction force for forming steric hindrance.In solids
Surface forms bilayer structure, and outer layer dispersing agent polar end carboxylate radical and water have compared with strong affinity, increases solids quilt
It is separate because of electrostatic repulsion between the degree solid particle of water wetting.
