PURPOSE:To provide the optical parts which have a high adhesive property to a synthetic resin, is not deteriorated in the adhesive property of films even after a moisture resistance test and less absorbs light by interposing a mixture composed of ZrO2 and TiO2 or a mixture composed of the ZrO2 and Ta2O5 as an adhesive layer to the synthetic resin. CONSTITUTION:A 1st layer, successively from the front surface side of a synthetic resin substrate to air side, is formed of the mixture composed of the zirconium oxide and titanium oxide or the mixture composed of the zirconium oxide and the tantalum oxide and a 2nd layer is formed of silicon dioxide or aluminum oxide. Further, a 3rd layer is formed of the mixture composed of the zirconium oxide and the titanium oxide or the mixture composed of the zirconium oxide and the tantalum oxide and a 4th layer is formed of the silicon dioxide. The antireflection film to the synthetic resin optical parts which have the high adhesive property to the synthetic resin, are not deteriorated in the adhesive property of the films even after the moisture resistance test while having the advantages of high stability and productivity, and less absorb light are obtd. in this way. |
