Abstract:
1. A 4-aminopyridinium compound represented by the formula (I): in which L 1 is —O—CO—, —CO—O—, —C≡C—, —CH═CH—, —CH═N—, —N═CH— or —N═N—; L 2 is a single bond, —O—CO—, —CO—O—, —C≡C—, —CH═CH—, —CH═N—, —N═CH— or —N═N—; m is 0 or 1; p is an integer of 1 to 10; each of R 1 and R 2 is independently an alkyl group having 1 to 8 carbon atoms, or otherwise R 1 and R 2 are combined to form a nitrogen-containing saturated ring; Z is cyano, an alkyl group having 1 to 12 carbon atoms, an alkoxy group having 1 to 12 carbon atoms, an acylalkyl group having 3 to 24 carbon atoms, an acylalkoxy group having 3 to 24 carbon atoms, an acyloxyalkyl group having 3 to 24 carbon atoms or an acyloxyalkoxy group having 3 to 24 carbon atoms; each of R 3 , R 4 and R 5 is independently a halogen atom; each of n1, n2 and n3 is independently 0 or 1; and X is an anion.
