Title:
テルル化合物含有高感度フォトサーモグラフィ材料及びその使用方法
Document Type and Number:
Japanese Patent JP3955821
Kind Code:
B2
Abstract:
Photothermographic imaging materials having increased photospeed are provided by certain tellurium chemical sensitizers that are added during the formulation of a photothermographic emulsion. These useful chemical sensitizers are represented by the following Structure I or II:wherein X<1 >and X<2 >independently represent halo, OCN, SCN, S(C=S)N(Ra)(Rb), S(C=S)ORa, S(C=S)SRa, S(P=S)(ORa)(ORb)2, S(P=S)(Ra)(Rb), SeCN, TeCN, CN, SRa, ORa, N3, alkyl, aryl, or O(C=O)Ra groups, Ra and Rb are an alkyl, alkenyl, cycloalkyl, heterocycyl, or aryl group, or Ra and Rb taken together can form a 5-, 6- or 7-membered heterocyclic ring, L is a ligand derived from a neutral Lewis base, R' is an alkyl or aryl group, m is 0, 1, 2, or 4, and n is 2 or 4 provided that when m is 0 or 2, n is 2 or 4, and when m is 1 or 4, n is 2, and further provided that multiple X<1>, X<2>, L, Ra, Rb, or R' groups in the molecule can be the same or different groups.
