Abstract 1. A RESIN COMPOSITION CONSISTING ESSENTIALLY OF THE REACTION PRODUCT OF A. A POLYISOCYANATE, PRESENT IN FROM 1 TO 40 PARTS BY WEIGHT, WITH B. A POLYFUNCTIONAL LINEAR POLYESTER HAVING AN AVERAGE MOLECULAR WEIGHT OF AT LEAST ABOUT 6,00 AND PRESENT IN FROM 99 TO 60 PARTS BY WEIGHT, SAID POLYESTER CONSISTING ESSENTIALLY OF THE RING-OPENING ESTERIFICATION REACTION PRODUCT AT NOT OVER 200* C. OF (1) A LINEAR POLYESTER CONSISTING ESSENTIALLY OF THE REACTION PRODUCT OF (A) A SATURATED ALIPHATIC OR AROMATIC DICARBOXYLIC ACID OR THE C1-4 ALKYL ESTERS THEREOF, WITH (B) A SATURATED ALIPHATIC OR ALICYCLIC DIHYDRIC ALCOHOL, SAID LINEAR POLYESTER HAVING AN AVERAGE MOLECULAR WEIGHT OF FROM ABOUT 1,000 TO ABOUT 8,000 AND A RATIO OF TERMINAL CARBOXYL GROUPS TO TERMINAL HYDROXYL GROUPS OF AT LEAST 1, WITH (2) A DIEPOXIDE, THE RATIO OF EPOXY GROUPS TO TERMINAL CARBOXYL GROUPS BEING FROM 0.5 TO 2.
A RESIN COMPOSITION CONSISTING ESSENTIALLY OF THE REACTION PRODUCT OF A. A POLYISOCYANATE, PRESENT IN FROM 1 TO 40 PARTS BY WEIGHT, WITH B. A POLYFUNCTIONAL LINEAR POLYESTER HAVING AN AVERAGE MOLECULAR WEIGHT OF AT LEAST ABOUT 6,00 AND PRESENT IN FROM 99 TO 60 PARTS BY WEIGHT, SAID POLYESTER CONSISTING ESSENTIALLY OF THE RING-OPENING ESTERIFICATION REACTION PRODUCT AT NOT OVER 200* C. OF (1) A LINEAR POLYESTER CONSISTING ESSENTIALLY OF THE REACTION PRODUCT OF (A) A SATURATED ALIPHATIC OR AROMATIC DICARBOXYLIC ACID OR THE C1-4 ALKYL ESTERS THEREOF, WITH (B) A SATURATED ALIPHATIC OR ALICYCLIC DIHYDRIC ALCOHOL, SAID LINEAR POLYESTER HAVING AN AVERAGE MOLECULAR WEIGHT OF FROM ABOUT 1,000 TO ABOUT 8,000 AND A RATIO OF TERMINAL CARBOXYL GROUPS TO TERMINAL HYDROXYL GROUPS OF AT LEAST 1, WITH (2) A DIEPOXIDE, THE RATIO OF EPOXY GROUPS TO TERMINAL CARBOXYL GROUPS BEING FROM 0.5 TO 2.
