  • Patent number: 7063265
    Abstract: A baggage tag in which a recording layer is formed on one side of a laminate, a circuit element is placed on the side opposite to the recording layer of the laminate, the laminate is a laminate of a paper sheet and a plastic film. The Clark degree of the laminate including the record layer in the recording direction, prescribed by JIS P8143, is 50 to 200. Therefore, the baggage tag is substantially free from problems due to defective printing and is free from the danger that the circuit element will come off and the baggage tag will be pulled off during the transport of the baggage.

  • Patent number: 5478793
    Abstract: A pressure sensitive recording material utilizing a color forming reaction between a colorless or light-colored basic dye and a color acceptor, and in which (1) a basic dye-containing layer and color acceptor-containing layer are formed on one surface of different substrates respectively, (2) a basic dye-containing layer and color acceptor-containing layer are formed on one surface and the other surface of a same substrate respectively, (3) a basic dye-containing layer and color acceptor-containing layer are superposed on one surface of a substrate or (4) a layer containing both basic dye and color acceptor is formed on one surface of a substrate, the pressure sensitive recording material being characterized in that the basic dye is at least one diarylmethane compound represented by the formula (1) given below, the basic dye being enclosed in synthetic high polymer microcapsules having a mean particle size of 3 to 15 .mu.m and an average film thickness of 0.1 to 0.7 .mu.
