| titleOfInvention | Stretch the manufacture method of layered product and the manufacture method and light polarizing film of stretching layered product and light polarizing film |
| abstract | The present invention relates to the manufacture method of stretching layered product and the manufacture method and light polarizing film of stretching layered product and light polarizing film.A kind of method for manufacturing stretching layered product is provided, the stretching layered product results in the light polarizing film that the deviation of transmitance is suppressed.The manufacture method of the stretching layered product of the present invention includes following process：The process that polyvinyl alcohol resin layer is formed on the thermoplastic resin base material of strip and layered product is made；And, by layered product conveying along its length on one side while stretch and make in the air the process for stretching layered product.The thickness for stretching the polyvinyl alcohol resin layer in layered product is less than 15 μm, the birefringence n of the positive direction of polyvinyl alcohol resin layer xy Width maxima and minima difference be 0.6 × 10 ‑3 Below. |
