specific example

[0041] Specific examples are: 2-hydroxy-4-methoxybenzophenone, 2,4-dihydroxybenzophenone, 2,2',4,4'-tetrahydroxybenzophenone, 2-hydroxy-4- Methoxybenzone-5-sulfonic acid, etc.

[0042] If it is not necessary to have alkali releasability, benzophenone-based or benzotriazole-based ultraviolet absorbers other than the above-mentioned ones can be used.

[0043] The infrared shielding agent may be an inorganic substance or an organic substance. As an infrared shielding agent, there are two types of infrared reflection type and infrared absorption type.

[0044] When it is an infrared reflective type, it is a perylene (perylene)-based black pigment (manufactured by BASF Co.), etc., and when it is an infrared-absorbing type, when it is an organic substance, it is aniline or polyaniline-based (manufactured by Japan Ka-ritto Co., Ltd. ) or organic pigments such as cyanine or phthalocyanine (manufactured by Nippon Shokubai Co., Ltd.). -02, ULA-01 produced by Kureha Chemicals—in this ...
