Among these conductive metal oxides, tin oxide and indium oxide are particularly suitable for use in the present invention because they are excellent in transparency and heat ray shielding property.

が粒子により散乱されるため透明性が得られない。The method for producing tin oxide or indium oxide is not particularly limited, and a conventional method can be adopted. However, in order to prevent the transparency from being impaired when dispersed in the resin, the particle size needs to be 0.1 μm or less. When the particle size exceeds 0.1 μm, transparency is not obtained because visible light is scattered by the particles.

量用いることは差し支えない。As a method for dispersing tin oxide and indium oxide in the plasticizer, a conventional dispersion method can be adopted, but a sand grinder, a homogenizer, and a super-dispersing agent are used to efficiently disperse the particles to a particle size of 0.1 μm or less. It is desirable to use a sonic disperser or the like. At this time, the dispersant may be used in an appropriate amount.

とが可能である。When the plasticizer has a high viscosity and is difficult to disperse, a method of diluting with a solvent to disperse it, or preliminarily dispersing in a solvent and then mixing with a plasticizer can be adopted. In this case, if it is necessary to remove the solvent, it can be removed by distillation.

If the amount is less than the weight part, the amount of the shielding substance is too small when added to the resin, and sufficient shielding performance cannot be obtained. Further, when it exceeds 150 parts by weight, the resin cannot be uniformly dispersed and a transparent resin cannot be obtained.
