A white ink can include an aqueous liquid vehicle, from 5 wt % to 70 wt % of a white metal oxide pigment having an average primary particle size from 5 nm to less than 100 nm, and from 0.005 to 10 wt % dispersant associated with a surface of the white metal oxide pigment. The white ink can also include from 2 wt % to 30 wt % core-shell latex particulates.
摘要:
An ink composition and an adhesion promoter are provided. The adhesion promoter is suitable for production while remaining the stronger adhesion. The adhesion promoter is formed by the reaction of at least one alpha hydroxy acid and at least one alpha hydroxy acid ester with the metal alkoxide. More specifically, by combining the renewable and green alpha hydroxy acid and safer plasticizing alpha hydroxy acid ester as reagent to react with the metal alkoxide, the eco-friendly and non-toxic adhesion promoter with superior adhesion for use in ink composition can be obtained. The ink composition includes the adhesion promoter, a pigment, a polymeric binder, and a solvent for the polymeric binder. The ink composition is odorless and colorless, and shows good wet crinkle resistance. Especially, the ink composition is suitable for printing on the food package.

摘要:
An organic vehicle comprising at least about 0.5 wt % and no more than about 45 wt % of at least one of a natural essential oil, based upon 100% total weight of the organic vehicle, at least about 0.5 wt % and no more than about 10 wt % of at least one resin, an organic solvent, and a thixotropic agent is provided. The invention also provides a solar cell and a method of forming a solar cell with the electroconductive paste of the invention.
摘要:
A flake-less molecular ink suitable for printing (e.g. screen printing) conductive traces on a substrate has 30-60 wt % of a C8-C12 silver carboxylate or 5-75 wt % of bis(2-ethyl-1-hexylamine) copper (II) formate, bis(octylamine) copper (II) formate or tris(octylamine) copper (II) formate, 0.1-10 wt % of a polymeric binder (e.g. ethyl cellulose) and balance of at least one organic solvent. Conductive traces formed with the molecular ink are thinner, have lower resistivity, have greater adhesion to a substrate than metal flake inks, have better print resolution and are up to 8 times less rough than metal flake inks. In addition, the shear force required to remove light emitting diodes bonded to the traces using Loctite 3880 is at least 1.3 times stronger than for commercially available flake-based inks.
摘要:
An aluminum chelate, a method for manufacturing the same and a photo cured ink including the same are revealed. First rosin resin is modified by epoxy and acrylic acid to get acrylic acid modified rosin resin. Then an aluminum chelating agent undergoes a chelation reaction with the acrylic acid modified rosin resin to form a plastic fluid whose chemical structure contains a photoreactive group and a chelate structure with aluminum. The plastic fluid can be added into photo cured inks so that the photo cured inks have better ink tack, ink flow, color density and stability.
摘要:
Fusing nanowire inks are described that can also comprise a hydrophilic polymer binder, such as a cellulose based binder. The fusing nanowire inks can be deposited onto a substrate surface and dried to drive the fusing process. Transparent conductive films can be formed with desirable properties.
