| titleOfInvention | Time temperature indicator comprising indolenin based spiropyrans containing a n-acetylamido or n-acetylester side chain |
| abstract | The present invention relates to time-temperature indicator (TTI) systems comprising indolenin based spiropyrans containing a N-acetylamido or N-acetylester side chain, especially to a time temperature indicator comprising at least one spiropyran indicator of formula (I) Wherein R 1 is hydrogen, —C 1 -C 18 alkoxy, —C 1 -C 18 alkylthio, —C 1 -C 18 alkyl-SO—, —C 1 -C 18 alkyl-SO 2 —, phenylthio, phenyl, halogen, —C 1 -C 18 alkylthio, —C 1 -C 18 alkyl-SO—, —C 1 -C 18 alkyl-SO 2 —, phenylthio, phenyl, halogen, —C 1 -C 18 alkyl or —NO 2 ; R 2 is hydrogen or —C 1 -C 18 alkoxy; R 3 is NO 2 or halogen; R 4 is hydrogen, —C 1 -C 18 alkoxy or halogen; R 5 is hydrogen, halogen, —C 1 -C 18 alkoxy, —COOH, —COO—C 1 -C 18 alkyl, —CF 3 or phenyl; R 6 is hydrogen or R 6 and R 7 form together a phenyl ring; R 7 is hydrogen; R a is hydrogen or —C 1 -C 6 alkyl; R b is hydrogen or —C 1 -C 6 alkyl, or together with R a form a 5-6 membered ring; Y is —CH 2 —COO—R 8 or —CH 2 —CO—N(R 10 )—R 9 ; or CH 2 —CO—N(R 10 )-L-N(R 10 ) CO—CH 2 — or Y is —CH 2 —CO—O-L′-O—CO—CH 2 — wherein R 8 is hydrogen, C 3 -C 18 alkyl or R 8 is ethyl with the proviso that R 6 and R 7 form together a phenyl ring; R 9 is phenyl, mesityl, phenyl-O-phenyl, phenyl-S-phenyl, phenyl once or more than once substituted by halogen, —CF 3 , C 1 -C 6 alkyl, —C 1 -C 6 alkoxy, carboxy, —COO—C 1 -C 6 alkyl whereby in case of a more than once substitution, the substituent can be the same or different; R 10 is hydrogen, C 1 -C 18 alkyl; L is 1,3 phenylene or 1,4 phenylene wherein the phenylene linker is optionally substituted by once or more than once by halogen, —CF 3 , C 1 -C 18 alkoxy, carboxy, —COO—C 1 -C 18 alkyl, —CONH2, —CON(C 1 -C 18 alkyl) 2 , nitro; or L is naphthalene, biphenylene or phenylene-O-phenylene wherein the naphthalene, biphenylene or phenylene-O-phenylene linker is optionally substituted once or more than once by halogen, —CF 3 , C 1 -C 18 alkyl, —C 1 -C 18 alkoxy, carboxy, —COO—C 1 -C 18 alkyl, —CONH 2 , —CON(C 1 -C 18 alkyl) 2 , nitro; L′ is 1,3 phenylene |
