One-side roughened rolled plane body and production thereof.

摘要

A one-side roughened plane body comprises a crystalline thermoplastic resin, one side of the body being roughened, the other side of the resin being smooth and the plane body being characterized in that the overall haze thereof is not less than 50% and that the internal haze thereof is not more than 15%. A process for producing a one-side roughened rolled plane body comprises the steps of rolling a plane body of a crystalline thermoplastic resin is rolled at a temperature equal to or less than the melting point of the thermoplastic resin and at a draft of 30% or more to thereby make the internal haze of the plane body 15%, and roughening one side of the plane body simultaneously with or after rolling to make the overall haze of the plane body not less than 50%.
