Process for bonding polyurethane to substrate
Abstract
Abstract POLYURETHANE COATINGS ARE CHEMICALLY BONDED TO SUBSTRATES, INCLUDING POLYOLEFINS AND LIKE SUBSTRATES WITH WHICH POLYURETHANES WILL NOT NORMALLY ACT, BY INCORPORATING, INTO THE POLYURETHANE COATING COMPOSITION USED TO PREPARE THE COATING, FROM 0.1 PERCENT TO 10 PERCENT BY WEIGHT, BASED ON POLYURETHANE, OF A SULFONYLAZIDE OF FORMULAE: A-(OOC-NH-C6H3(-RY)-(SO2-N3)X)M, AND 2,4,6-TRI(O=), WHEREIN A IS THE RESIDUE OF AN ALIPHATIC ALCOHOL HAVING M HYDROXYL GROUPS AND A MOLECULAR WEIGHT LESS THAN 300, R IS LOWER-ALKOXY OR HALO, X IS 1 TO 2, Y IS 0 TO 2, AND X+Y IS $3, THE SO2N3 GROUPS ARE IN 3, 4 OR 5-POSITIONS IN THE PHENYL RINGS, PROVIDED THAT ONE SUCH POSITION IS ALWAYS UNSUBSTITUTED AND M IS 1 TO 6. THE CHEMICAL BONDING CAN BE CARRIED OUT BY IRRADIATION IMAGEWISE THEREBY MAKING THE COMPOSITIONS USEFUL IN PHOTORESIST SYSTEMS. 1,3,5-TRI(RY,(N3-SO2)X-PHENYL)-PERHYDRO-S-TRIAZINE
