Abstract
Provided is an assembly having excellent flexural elastic modulus and joint strength and having suppressed reduction of transparency due to increased haze in the presence of water vapor generation. The assembly includes a plurality of shaped products having a thermoplastic resin as a material and a joining layer joining the shaped products to one another. The joining layer contains at least one type of cycloolefin polymer and a solvent component having a boiling point in a specific range. The assembly contains the solvent component having a boiling point in a specific range in a specific trace concentration range.
Claims5
An assembly comprising:
- a plurality of shaped products having a thermoplastic resin as a material;
- and
- a joining layer joining the shaped products to one another, wherein
- the joining layer contains at least one type of cycloolefin polymer and a solvent component having a boiling point of not lower than 70° C. and not higher than 150° C., and
- the assembly contains not less than 100 mass ppm and not more than 800 mass ppm of the solvent component having a boiling point of not lower than 70° C. and not higher than 150° C. relative to total mass of the assembly.
