摘要:
The present invention relates to a thermochromic color-memory composition containing: (I) an electron donating coloring organic compound, (II) an electron accepting compound, and (III) an ester compound represented by the following formula (1) as a reaction medium which controls color reaction of the components (I) and (II): (in the formula, X represents any of a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, and a halogen atom, m represents an integer of from 1 to 3, and n represents an integer of from 1 to 20).
摘要:
A main object of the present invention is to provide a thermosensitive recording material having excellent recording color developability and recording image quality, having no inhibition of a color-developing reaction due to the adhesive component after being processed into a thermosensitive recording label (glue desensitization), and being able to withstand long-term storage while retaining excellent recording performance. The present invention is a thermosensitive recording material (1) having at least an anchor layer (1) containing a sizing agent on a support, an undercoat layer containing at least one member selected from the group consisting of plastic hollow particles and sizing agents on the anchor layer (1), and a thermosensitive recording layer containing a leuco dye and a coloring agent on the undercoat layer; and is a thermosensitive recording material (2a) having an anchor layer (2) containing specific amounts of a pigment and a specific sizing agent on a support, and a thermosensitive recording layer containing a leuco dye and a coloring agent on the anchor layer (2); a thermosensitive recording material (2b) having an anchor layer (2) containing a pigment and a specific sizing agent on a support, and a thermosensitive recording layer containing a leuco dye and a specific coloring agent on the anchor layer (2); or a thermosensitive recording material (2c) having an anchor layer (2) containing a sizing agent and a water resistance-imparting agent on a support, and a thermosensitive recording layer containing a leuco dye and a coloring agent on the anchor layer.

摘要:
The present invention provides a heat-sensitive recording material having a high recording density, excellent plasticizer resistance in recorded portions, and excellent resistance to thermal background fogging in high-temperature environments. The heat-sensitive recording material includes a heat-sensitive recording layer containing a specific sulfonamide compound.
摘要:
A substrate coated with a markable ink formulation, comprising a thermo activated acid generator (TAG) and a halochromic leuco dye. The thermo activated acid generator is selected form the group consisting of: an amine salt of an organic metal compound comprising boron or silicone and amine neutralized polyalkylnaphthalene polysulphonic acid derivatives. Further, the substrate is covered by a thermoplastic polymer layer, such that the ink formulation is situated between the substrate and the thermoplastic polymer layer and/or in the thermoplastic polymer layer.
