Abstract:

An aspect of the present invention is a process for modifying a substrate in areas that are exposed to actinic radiation, having the steps a providing on the substrate functional groups adapted for conversion to oxygen-containing photoproducts upon exposure to actinic radiation b exposing at least a portion of the substrate to the actinic radiation, converting the functional groups in an exposed region of the substrate to the photoproducts c contacting the photoproducts with a primary or secondary amine in the presence of hydrogen ions, forming imine groups and d contacting the imine groups with a reducing agent, forming amine groups on the substrate in the exposed region. Another aspect of the present invention is a process for modifying a substrate in areas that are unexposed to actinic radiation, having the steps a providing on the substrate aryl functional groups adapted for conversion to oxygen-containing photoproducts upon exposure to actinic radiation b exposing a portion of the substrate to the actinic radiation, converting the aryl functional groups in an exposed region of the substrate to the photoproducts, and not converting the aryl functional groups in an unexposed region of the substrate to the photoproducts and c contacting the aryl functional groups in the unexposed region of the substrate with a compound adapted for physisorption to the aryl functional groups, preferentially physisorption the compound onto the substrate in the unexposed regions.
