Abstract
The present invention provides a plasma display front panel comprising a transparent substrate which is produced by molding a resinous composition containing the following components (a) to (c), and has a 50% or more transmittance of light with a wavelength in the range of 450 nm to 650 nm, and a 30% or less transmittance of light with a wavelength in the range of 800 nm to 1000 nm; (a) a monomer having an unsaturated double bond and/or polymer thereof; (b) a phosphorus atom-containing compound; and (c) a copper atom-containing compound. The attachment of this to the front of a plasma display can prevent the effect of near-infrared rays arising from the display on the peripheral devices.
Claims19
A plasma display front panel comprising a transparent substrate, said transparent substrate being obtained by molding a resinous composition comprising the following components (a) to (c), and having a 50% or more average transmittance of light with a wavelength in the range of 450 nm to 650 nm and a 30% or less average transmittance of light with a wavelength in the range of 800 nm to 1000 nm:
- (a) a monomer having an unsaturated double bond and/or polymer thereof;
- (b) a phosphorus atom-containing compound represented by the following general formula:
- CH.sub.2 =C(X)COO(Y).sub.m --!.sub.3-n --P(O)--(OH).sub.n
- wherein x denotes a hydrogen atom or methyl group, when said Y is an oxyalkylene group with 2 carbon atoms, m is a number average of 8 to 20, when said Y is an oxyalkylene group with 3 carbon atoms, m is a number average of 5 to 20, and when said Y is an oxyalkylene group with 4 carbon atoms, m is a number average of 4 to 20, and n represents 1 or 2;
- and
- (c) a copper atom-containing compound.
