The present invention provides photoresist monomers, photoresist polymers derived from the same, processes for producing such photoresist polymers, photoresist compositions comprising such polymers, and processes for producing a photoresist pattern using such photoresist compositions. It comprises an active region for converting incident light into charge carriers, photogates for generating a lateral electric potential ) across the active region, and an integration gate for storing charge carriers generated in the active region and a dump site. The insert is made of a different material from that of the rest of the closure. In a preferred embodiment, such cross-linked high amylose starch is prepared in the following steps: granular cross-linking and additional chemical modification of high-amylose starch; thermal gelatinization of the starch from step ; and drying the starch from step to yield a powder capable of being used as a controlled release excipient. The sacrificial structure is removed. In order to improve the conventional window arrangement of the generic type to the effect that mounting can be made easier while the appearance is improved visually and esthetically, the invention provides that the trim elements and the window pane are connected to one another in a materially joined andor frictionally locking fashion.
