摘要:
Radiation (thermal and light)-sensitive polymers are provided and are characterized by (1) a recurring unit of the formula: WHEREIN R2 is lower-alkoxy or phenyl, one of X and Y is -COOR and the other is -COR1, R is an azidosulfonylcarbanilyloxy alkylene group and R1 is -O-dye, -NH-dye or hydroxyarylamino, or (2) a combination in the same polymer chain of recurring units having the formulas: WHEREIN ONE OF X1 and Z1 represents -COOH and the other represents -COOR as defined above, and WHEREIN ONE OF X2 and Z2 represents -COOH and the other represents -COR1 as defined above. The polymers can be chemically bonded to substrates, such as those containing C - H bonds only (e.g., polyolefins), which are not normally dye receptive. The bonding is effected by exposure to appropriate radiation; the exposure can be carried out imagewise to produce an appropriate image on the substrate. Accordingly, the polymers of the invention find use in the photoresist, printing and like arts.

摘要:
Methods of adhering polymeric materials to a substrate, either directly or through linker molecules, are disclosed. Structures, for example, microstructures, including microwells and arrays of microwells, may be readily formed using the methods. In some embodiments, microstructures formed completely from polymeric materials are provided, making it possible to tailor the chemical and physical properties of the microstructures. For example, microwells having a bottom comprising a polar polymeric material and well sides/top comprising a non-polar polymeric material are provided. Biochemical reagents may be easily delivered to such nullsmart wellsnull because the intrinsic attraction of the well bottom for the reagents and the intrinsic repulsion between the well sides/top combine to direct the reagents to the wells.

摘要:
A photosensitive resin having at least one group as shown below in Chemical Formula (1) in a molecule. ##STR1## wherein n represents an integer from 1 to 10. Since the photosensitive resin has an azido group in a molecule having an adsorption region higher than 300 nm, the resin is highly sensitive. Therefore, an emulsion coating photo mask or a soda glass photo mask, which allows light permeation within the abosorption region of the azido group and is cheap in industry, can be used as the photo mask for the photosensitive resin of the invention. The photosensitive resin is particularly useful as a photo resist.
