PURPOSE:To ensure that excellent heat resistance and moisture resistance are obtained by forming a specific condensed bond using a pyrazolothiadiazine derivative. CONSTITUTION:Pyrazolothiadiazine coloring matter has a condensed ring as expressed by the formula. In the formula, R1, R2 are hydrogen atom and an alkyl group respectively and can form a 5-member or 6-member ring. R3 to R6 are hydrogen atom, halogen atom, an alkyl group, a substitution alkyl group, an alkoxy group or a substitution group, and R1 and R4, R2 and R6 can form a 5-member or 6-member ring by bonding each other. R7 is hydrogen atom or a substitution group; Z is a non-metal atom group required for the formation of a heterocyclic 5 to 7-member ring and a non-metal atom group required for the formation of a benzene ring or a naphthalene ring; n is 1 or 2. Thus it is ensured to obtain excellent heat resistance and moisture resistance. |
