A light-scattering film is provided and includes a transparent support having thereon at least a light-scattering layer. When substantially parallel light is incident on a surface of the film at an incident angle of 5&#xb0;, the reflectance for an angle &#x3b8; in the light-receiving part measured in a plane containing the film normal line and the incident direction is R(&#x3b8;), the value obtained by normalizing R(&#x3b8;) by the reflectance of regular reflection is Rrel(&#x3b8;), and the value calculated from the maximum variation |dRrel(&#x3b8;)/d&#x3b8;|max for the angle &#x3b8; is a scattering coefficient A (formula 1), the reflection coefficient B (formula 2) calculated from the scattering coefficient A and the 5&#xb0; specular reflectance Rs is from 2.0 to 5.0.Scattering coefficient=1/(10rel(&#x3b8;)/&#x3b8;|max)&#x2003;&#x2003;(Formula 1)Reflection coefficient=2.2&#xd7;log 10()&#x2212;7.5&#xd7;log 10()+5.9&#x2003;&#x2003;(Formula 2)

Light-scattering film, polarizing plate and image display

An optical filter comprising a transparent support having a tensile impact strength of 392 kJ/mor more having provided thereon a filter layer having an absorption maximum in the range of from 560 to 620 nm.

Optical filter

An optical filter comprising a filter layer absorbing visible light, a transparent support, in particular a transparent support comprising a biaxially stretched film, and an antireflection layer, with which an image display such as a plasma display is equipped for preventing reflection and improving color reproduction. An optical filter comprising a transparent support having provided at least on one side of the support a filter layer containing a dye and a polymer binder, wherein an antireflection layer having an antireflection property to visible light is provided on the side opposite to the side on which the filter layer is provided when the filter layer is provided on either one side, and the antireflection layer is provided on either one side when the filter layers are provided on both sides, and the transparent support comprises a biaxially stretched film having a thickness of from 10 to 500 &#x3bc;m.

An optical filter comprises a transparent support and at least one filter layer. The optical filter has an absorption maximum in the wavelength region of 560 to 620 nm. The optical filter also has another absorption maximum in the wavelength region of 700 to 1,200 nm. A plasma display panel having a display surface covered with an optical filter is also disclosed.

Optical filter having two absorption maximums

An optical filter comprises a transparent support and a filter layer. The filter layer has an absorption maximum in the wavelength range of 500 to 550 nm. The filter layer further has another absorption maximum in the wavelength range of 560 to 620 nm. The optical filter has a transmittance in the range of 40 to 85% at the absorption maximum in the wavelength range of 500 to 550 nm. The optical filter further has a transmittance in the range of 0.01 to 80% at the absorption maximum in the wavelength range of 560 to 620 nm.

Optical filter comprising transparent support and filter layer having

A method of producing a photographic polyester laminate support having a laminate of layers of at least two kinds of polyesters can provide low formation of scratches in a camera and a curl in the film's width direction. In the support, the glass transition temperature (Tg) of each polyester of the laminate is within the range of from 90.degree. C. to 200.degree. C. and the laminate is subjected to heat-fixing in a temperature range as defined by formula (1):
