Abstract

PURPOSE:To obtain an inexpensive base material for light scattering sheet by using a base plate consisting of polyethylene having a specified mol.wt. formed to a sheet or a plate without adding any additive. CONSTITUTION:Polyethylene contg. no additive and having 500,000-2,000,000mol. wt. is used as a base material for a light scattering sheet in a form of a sheet or a plate without executing any surface working. Since the light scattering sheet comprises polyethylene having a mol.wt. in a fixed mol.wt. range and contg. no additive, an inexpensive light scattering polyethylene sheet capable of causing appropriate intermolecular irregular reflection between layers of the sheet or plate may be obtd. or stabler light scattering effect of the irregular reflection may be attained. Thus, an inexpensive and flexible base material for light scattering sheet is obtd. easily.

DETAILED DESCRIPTION OF THE INVENTION At present, it is generally used as a light source material for liquid crystal displays or
As base materials for automobile brake lights, side lamps, etc. and illuminated signboards, synthetic resin materials with high light transmittance are made into sheets by adding various light diffusing agents, and these sheets are surface-treated. This prevents the transmission of parallel light rays and allows more diffusely reflected and diffusely refracted light to pass through.

The present invention is that additive-free polyethylene of a certain molecular weight range can be formed into a sheet or plate and used as a light-diffusing base material without any surface treatment.

In the conventional method, there were many technical difficulties in forming a sheet with a light diffusing agent more uniformly dispersed, but this invention simply uses a cheaper material in a constant molecular weight range without any additives. This is due to the discovery that moderate intermolecular diffuse reflection or diffuse refraction between the eyebrows of a polyethylene sheet or plate has more stable light scattering properties.

This discovery means that cheaper, more flexible, light-diffusing substrates can be provided more easily.
