摘要：
Coloring matters and filters for plasma display panels, which can effectively screen the neon emission radiated from plasma display panels. Squarylium compounds represented by the following formula (I): [in the formula (I), R is a halogen atom, an alkyl group which may have a substituent, an alkoxy group which may have a substituent, or an alkenyl group which may have a substituent, m is an integer of from 1 to 4, and n is an integer of from 0 to 4], and filters for plasma display panels, made by laminating layers containing these compounds with layers containing ultraviolet absorbers and, if necessary, providing additionally near infrared screening layers, antireflection layers and/or non-glare layers.
