摘要:
An ink of this invention contains a self-dispersible pigment having a phosphonic acid group bonded directly or through another atomic group to the surface of the self-dispersible pigment, polyurethane resin particles, a monovalent inorganic salt, and water.
摘要:
The ejection liquid of the present invention includes a compound having a guanidine group, and a carboxyl group or a sulfonic acid group in one molecule, and being represented by the general formula (1), or a salt of the compound, for the purpose of stably ejecting a solution including at least one of a protein and a peptide by imparting thermal energy to the solution.
摘要:
There are provided an ejection liquid that contains at least one of proteins and peptides and can be ejected stably by an ink jet system, and a method and apparatus for ejecting a liquid containing at least one of proteins and peptides using the ejection liquid. A specific amine is added to an aqueous solution of at least one of proteins and peptides to thereby improve the applicability to ejection by the ink jet system.
摘要:
An ejection liquid capable of being stably ejected based on a system using thermal energy even if the liquid contains at least one selected from the group consisting of proteins and peptides, and a method and an apparatus for ejecting the liquid containing at least one selected from the group consisting of proteins and peptides using this system are provided. The applicability of the liquid for use in an inkjet system using thermal energy is improved by adding at least one selected from the group consisting of amino acids and salts thereof and a surfactant to an aqueous solution containing at least one selected from the group consisting of proteins and peptides.
