DOCUMENT TYPE: Patent CA Section: 42 (Coatings, Inks, and Related Products) 3-(Ethoxyoxaloyl)-N-methyl-2-pyrrolidinone (I) [60044-10-2], 3-acetyl-N-methyl-2-pyrrolidinone [60044-08-8], a-acetyl-g-butyrolactone [517-23-7], or 3-acetyl-1-thia-2-cyclopentanone [65286-54-6] was used with 1,3-dithiane [505-23-7] or 1,4-dithiane [505-29-3] as a promoter compn. for unsatd. polyester resin coatings. Polyester resins contg. the promoter compns. had a long shelf life and hardened rapidly in the presence of catalysts. Thus, a polyester resin soln. contg. Co (as octoate) 0.03, paraffin 0.1, I 0.4 and 1,3-dithiane 0.4% had a long shelf life and hardened in the presence of a cyclohexanone peroxide catalyst after 7 min.
