Abstract

PURPOSE:To provide a resin composition having such special optical properties that it is highly transparent when the quantity of incident light is small whereas its light transmittance decreases to limit the quantity of transmitted light and to allow the transmission of a limited quantity of light, to provide a desirable production process therefor and to provide a light limiter fully utilizing the excellent optical properties of the composition. CONSTITUTION:The resin composition comprises a fullerene having a closed-shell structure and a transparent resin having a transmittance of 50% or above, the content of the fullerene being 0.001-10wt.% based on the transparent resin. The composition is prepared by dissolving the fullerene and the transparent resin in one and the same solvent or dissolving them in separate intermiscible solvents and combining the obtained solutions together and removing the solvent or solvents from the (combined) solution. The limiter is formed by using a molding of this composition as a base material.

As the performance of the light limiter and the light shielding plate, properties such as high-speed response to light, high light transmittance at low brightness and low light transmittance at high brightness are required.

Most of the light-shielding plates and light limiters currently used are those in which dyes are dispersed, metal complex particles are dispersed, or the amount of light is adjusted by a polarizing plate. However, in the case of using these conventional type light shields or light limiters, the light intensity dependence of the light transmittance in the light shields or light limiters is low,
There is a problem that the amount of light transmission is significantly reduced in a state where it is not necessary to shield with low-brightness light, or when it is not shielded, it is troublesome to remove the polarizing plate or rotate the polarizing plate. Needed operation.
On the other hand, in the case of high-brightness light, the light blocking is insufficient and the intensity of transmitted light becomes too large, and as a result, the problem that the damage to the optical sensor cannot be sufficiently reduced often occurs. That is, it is hard to say that the conventional light-shielding plates and the optical limiters of this kind all sufficiently satisfy the above-mentioned required performances, and it has been desired to improve their performances.

There are some phthalocyanine-dispersed solutions and the like which show a property that the amount of transmitted light does not change significantly even when the incident light increases, but there is a limit to the use in such a solution state. Further, in order to reduce the amount of transmitted light at high brightness, it is necessary to sacrifice the transparency at low incident light amount, which is not practical from this point as well.
