摘要:
Waste reduction, including hazardous waste reduction in photoimaging processes can be accomplished by improving diffusional resolution of cationic curable compositions. The addition of fluorinated polymers including fluorinated surfactants provides improved diffusional resolution in cationic and/or radical based photoimaging formulations allowing for image accuracy improvements, and reduced product and process waste quantity and disposal cost. These fluorinated surfactants also allow for increased cure speed, and non-hazardous constituent formulations that result in less wasted material and time.

摘要:
A frequency controlled electro-optical device includes a substrate having transparent conductive control sections patterned thereon to selectively control the optical state of an electro-optical layer. Each of the control sections are partially electrically isolated from each other by crack lines, which allows for electrical communication between adjacent/proximate control sections to occur. As such, an electrical control signal applied directly to one control section forms an electric field in that control section, and also induces an electrical field in adjacent control sections that are not in direct receipt of the control signal. Therefore, the number of electrical connections required for coupling to a driving circuit to operate the device is minimized, thereby allowing the device to be fabricated with reduced complexity and cost.
