Title:
導電性インキ、導電回路、及び非接触型メディア
Document Type and Number:
Japanese Patent JP5071105
Kind Code:
B2
Abstract:
This invention provides an electrically conductive ink comprising an electrically conductive material and a vinyl chloride/vinyl acetate/hydroxyalkyl (meth)acrylate copolymer resin. There is also provided a noncontact-type medium comprising a base material and, provided on the base material, an electrically conductive circuit formed using the electrically conductive ink, and an IC chip mounted in the state of being electrically conducted to the electrically conductive circuit. An electrically conductive circuit, which is in a thin film form, can be used as an antenna circuit for noncontact-type media, has a low volume resistivity on the order of 10 -5 ©·cm, and is highly reliable under a high temperature and high humidity environment, can be formed by using the electrically conductive ink at a low temperature in a short time.
