Abstract
An ink which can be imparted with an adhesiveness on application of an electric current is obtained by impregnating a crosslinked substance such as guar gum or polyvinyl alcohol compound with a liquid dispersion medium such as water. The ink is supplied with a pattern of energy to be provided with an adhesive pattern, which is then transferred to a recording medium, such as plain paper, directly or by the medium of an intermediate transfer medium to form an ink pattern corresponding to the energy pattern applied. The ink further comprises a buffer action-imparting substance and is excellent in storage stability and stability of performances during a continuous use.
Claims15
A nonadhesive image recording ink, comprising:
- a dispersion medium which is liquid at room temperature;
- substance which is a reversible crosslinked structure selected from the group consisting of irregularly crosslinked, or a network, honeycomb or helix and impregnated with the dispersion medium;
- and a pH buffering electrolyte, wherein said ink is imparted with adhesiveness upon application of electric current and has a ratio (G"/G') of loss elasticity modulus (G") to storage elasticity modulus (G') of from 0.1-10, and said crosslinked structure is at least partially reversibly converted into a sol. state upon application of electric current.
A nonadhesive image recording ink, comprising:
- a dispersion medium which is liquid at room temperature;
- a substance which is a reversible crosslinked structure selected from the group consisting of irregularly crosslinked, or a network, honeycomb or helix and impregnated with the dispersion medium;
- and an ionic surfactant, wherein the ink is imparted with adhesiveness upon application of electric current and has a ratio (G"/G') of loss elasticity modulus (G") to storage elasticity modulus (G') of from 0.1-10, and said crosslinked structure is at least partially reversibly converted into a sol. state up application of electric current.
A nonadhesive image recording ink, comprising:
- a dispersion medium which is liquid at room temperature a substance which is reversibly crosslinked structure selected from the group consisting of irregularly crosslinked, or a network, honeycomb or helix and impregnated with the dispersion medium;
- and a solid metal oxide acid, wherein the ink is imparted with adhesiveness upon application of electric current and has a ratio (G"/G') of loss elasticity modulus (G") to storage elasticity modulus (G') of from 0.1-10, and said crosslinked structure is a least partially reversibly converted into a sol. state upon application of electric current.
