<p>PROBLEM TO BE SOLVED: To obtain a white infrared light-reflecting material that is an organic compound, has high infrared ray reflection and is hardly soluble in organic solvent with high color fastness to light. SOLUTION: The objective infrared light-reflecting material is made of a compound represented by the general formula, specifically 4,5,6,7-tetrachloro- phthalimide, 3-imino-4,5,6,7-tetrachloroisoindolenin-1-one, 1,3-dimino-4,5,6,7- tetrachloroisoindoline. These compounds are white, show high reflection of infrared rays with low solubility in organic solvent and high color fastness to light.</p> |
