摘要：
A THERMOSETTING COATING COMPOSITION OF A URETHANE POLYMER THAT CURES INTO A DURABLE, FLEXIBLE COATING IS THE SUBJECT OF THIS INVENTION; THE FILM-FORMING CONSTITUENTS OF THE COATING COMPOSITION ARE (1) AN ORGANIC POLYISOCYANATE, AND (2) A POLYMER THAT HAS A BACKBONE OF POLYMERIZED ETHYLENICALLY UNSATURATED MONOMERS AND HAS ATTACHED DIRECTLY TO ITS BACKBONE ESTER GROUPS OF THE FOLLOWING STRUCTURE
-COO-R1-OH AND
-COO-R1-OOC-R2-COO-CH2-CH(-OH)-CH2-OOC-R3
OR AN ISOMER THEREOF, WHEREIN R1, R2 AND R3 ARE HYDROCARBON RADICALS; THIS NOVEL COATING COMPOSITION IS PARTICULARLY USEFUL AS A HIGH QUALITY INDUSTRIAL FINISH AND CAN BE USED TO PAINT AUTOS, TRUCKS, AIRCRAFT, RAILWAY EQUIPMENT AND THE LIKE.
