Radiation sensitive polymers
Abstract
Abstract RADIATION (THERMAL AND LIGHT)-SENSITIVE POLYMERS ARE PROVIDED AND ARE CHARACTERIZED BY (1) A RECURRING UNIT OF THE FORMULA: -CH(-X)-CH(-Y)-CH(-R2)-CH2- WHEREIN R2 IS LOWER-ALKOXY OR PHENYL, ONE OF X AND Y IS -COOR AND THE OTHER IS -COR1, R IS AND AZIDOSULFONYLCARBANILYLOXY ALKYLENE GROUP AND R1 IS -O-DYE, -NH-DYE OR HYDROXYARYLAMINO, OR (2) A COMBINATION IN THE SAME POLYME CHAIN OF RECURRING UNITS HAVING THE FORMULAE: -CH(-X1)-CH(-Z1)-CH(-R2)-CH2- WHEREIN ONE OF X1 AND Z1 REPRESENTS -COOH AND THE OTHER REPRESENTS -COOR AS DEFINED ABOVE, AND -CH(-X2)-CH(-Z2)-CH(-R2)-CH2- WHEREIN ONE OF X2 AND Z2 REPRESENTS -COOH AND THE OTHER REPRESENTS -COR1 AS REFINED 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 BY 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.
