FUJIFILM developed several thermo/pressure sensitive recording materials which have been introduced the poly (urethane-urea) microcapsule. That microcapsule were prepared by an interfacial polymerization process, and we can control “the glass transfer temperature” and “the mechanical properties” of the microcapsule shell. So we had contributed to the high functionality for thermo/pressure sensitive materials.

Now, as the thermo sensitive material, we are continuing the business of Dry Thermal Imager “DRYPIX Lite” for medical. The recording film “DI-HT” for DRYPIX Lite is applying the microcapsule technology in order to achieve the long storage life and better transparency to attain enhanced image quality.

As the pressure sensitive material, “Pressure Measurement Film PRESCALE” which could measure visual verification of pressure distribution is sold. PRESCALE is applying the microcapsule technology in order to achieve the precisely measure wide range pressure, distribution, and balance.

In this paper, we describe the technologies for the formulation of poly (urethane-urea) microcapsule and explain the technologies which introduced to our materials.
