First claim
Opening claim text (preview).
What is claimed is: 1. A composition containing a phthalocyanine derivative represented by the following formula: where R 1 to R 8 are independently an alkyl group, M is Si, each of R 9 and R 10 is any one of substituents represented by the following formulas, R 11 to R 13 are independently an alkyl group, and R 14 to R 18 are independently an alkyl group or an aryl group: 2. The composition according to claim 1 , wherein R 1 to R 8 in Formula (1) are alkyl groups containing five or less carbon atoms. 3. The composition according to claim 1 , wherein the phthalocyanine derivative is one of compounds represented by the following formulas: where Ar is an aryl group and X is an alkyl group containing ten or less carbon atoms. 4. The composition according to claim 1 , wherein at least one hydrogen atom contained in at least one selected from the group consisting of R 9 and R 10 in Formula (1) is substituted by a fluorine atom or a fluorine-containing group. 5. The composition according to claim 4 , wherein R 9 and R 10 in Formula (1) are represented by Formula (5), R 17 and R 18 in Formula (5) are independently an aryl group, and at least one hydrogen atom contained in at least one selected from the group consisting of R 17 and R 18 is substituted by a fluorine atom or a fluorine-containing group. 6. The composition according to claim 5 , wherein R 17 and R 18 in Formula (5) are independently a phenyl group and at least one hydrogen atom contained in at least one selected from the group consisting of R 17 and R 18 is substituted by a fluorine atom or a trifluoromethyl group. 7. The composition according to claim 4 , wherein the phthalocyanine derivative is any one of compounds represented by the following formulas:
