  • Patent number: 5747156
    Abstract: A magnetic recording layer is provided on a base, and a thermosensitive recording layer is provided on the magnetic recording layer through a thermoplastic layer. The thermosensitive recording layer is a coating layer which is mainly composed of low melting point non-magnetic metal powder having shape anisotropy and a binder. The thermoplastic layer is prepared from a material having a melting temperature which is lower than that of the non-magnetic metal powder forming the thermosensitive recording layer, in a thickness of 1 to 20 .mu.m. Information is printed on the thermosensitive recording layer with a thermal head.

  • Patent number: 4727055
    Abstract: A heat-sensitive record material having a thick base support consisting of at least two base sheets and at least one binder layer, said base support weighing at least 150 g/m.sup.2 and having an excellent dimensional stability without accompaniment of any cockles and any background fogginess. It is particularly suitable for use in providing tags, tickets, cards, price marks etc. A process for the production of said heat-sensitive record material by the use of a binder consisting essentially of at least one thermoplastic polymer for which the vicat softening temperature is 20.degree. C. to 180.degree. C. and preferably 30.degree. C. to 160.degree. C.

  • Patent number: 4489336
    Abstract: A pressure sensitive manifold paper is prepared with use of microcapsules having enclosed therein an organic solvent, a color former contained in the solvent, and an alkylphenol compound and/or a mercaptan added to the solvent. The paper affords prints resistant to light and has a color forming layer which remains free of coloration and gives prints of original color even when exposed to light.

  • Patent number: 4218506
    Abstract: The recording material comprises a base sheet and a color former coating layer formed on a surface of the base sheet and the color former coating layer is formed by coating a surface of the base sheet with a coating composition comprising an aqueous dispersion of microcapsules each encapsulating a hydrophobic color former material therein and having a capsule wall of a gelated hydrophilic colloid material. The dispersion further includes(a) a hardener for the hydrophilic colloid material and(b) a water soluble alkali salt of a copolymer of at least one olefinic monocarboxylic acid with at least one monomer copolymerizable with the olefinic monocarboxylic acid.
