Latest Patents

One of his latest patents is titled "Photosensitive systems showing visible indication of exposure." This invention provides new compositions that change color upon exposure to actinic radiation. The compositions contain a photosensitive onium salt, such as iodonium or sulphonium, and a dyestuff that changes color when protonated. These compositions may also include a resin, particularly an epoxy resin, which is curable by the onium salt upon exposure. They are especially useful as coatings for making screen stencils or producing lithographic printing plates. Another significant patent is "Water-based photopolymerizable compositions and their use." This patent describes aqueous dispersions that comprise water, a cationically curable compound, and a photosensitive onium salt. These compositions are beneficial for creating printing screens, lithographic plates, and printed circuit resists. After exposure, the un-cured composition can be easily removed by washing with water.
