  • Patent number: 10108834
    Abstract: A method for generating a two-dimensional barcode, including: obtaining a protection-encoding pattern based on a mask pattern reference, the mask pattern reference being a reference for identifying a mask pattern that is applied to a module group, the module group being composed of a plurality of modules, each module being a unit cell constituting the two-dimensional barcode; obtaining a protection-encoded code block by protection-encoding a code block with the protection-encoding pattern, the code block having at least a data codeword; generating the module group based on the protection-encoded code block; and generating the two-dimensional barcode having the module group to which the mask pattern is applied.

  • Publication number: 20130022819
    Abstract: An object of the present invention is to provide a method for producing a transfer body, which method neither causes adhesion failure at the interface between a transferring film and a substrate, nor causes interlayer peeling in the transferring film. Another object of the present invention is to provide a method for producing a transfer body with high productivity, which method neither causes breakage of a functional pattern forming a transferring layer during peeling of a release film from the transferring film, nor causes any damage to the substrate during separation of an attaching roller and a peeling roller from the substrate.

  • Publication number: 20100086752
    Abstract: Transfer films for firing which have the excellent property of transferring a functional pattern and enable a pyrolysis gas generated by the firing of organic substances to be released smoothly, and which can form on a substrate a functional pattern free from defects such as a shape or function failure. One of the transfer films for firing comprises a release film and a multilayered structure formed so as to be in contact with one of the surfaces of the release film. The multilayered structure includes both a pressure-sensitive adhesive layer for bonding the transfer film for firing to a surface of a substrate and a functional pattern formed between the release film and the pressure-sensitive adhesive layer. The functional pattern comprises inorganic particles and a first organic substance removable by firing, and the pressure-sensitive adhesive layer comprises a second organic substance removable by firing and different from the first organic substance.

  • Publication number: 20100086754
    Abstract: A transfer film for firing which has a multilayer structure including a functional pattern and a pressure-sensitive adhesive layer. The multilayer structure is free from a shape failure of the functional pattern and a decrease in adhesive force of the adhesive layer, and has the excellent transferability to a substrate. The transfer film gives a fired functional pattern free from defects such as a shape or function failure. The transfer film for firing is one for use in forming a fired functional pattern by transferring a multilayer structure including a functional pattern to a surface of a substrate and firing it. The transfer film comprises a release film and a multilayer structure formed so as to be in contact with one of the surfaces of the release film. The multilayer structure includes a functional pattern and a contact layer which has been formed so as to be in direct contact with the surface of the functional pattern and is constituted of one layer or a larger number of layers.
