Embodiment 1

[0123] A specific example 1 of the present invention will be described. In Embodiment 1, paint was manufactured by using the in-line mixing devices 53 , 58 , and 63 described in the above-mentioned embodiments in a paint manufacturing process to be described later. The film is then produced by casting the dope. Specific conditions for the production of the film are described below; however, the present invention is not limited to Example 1.

[0124] The content of each part by mass used in Example 1 is as follows.

Abstract

An inline mixing device (53) is constituted of a sulzer mixer (160) disposed in an upper stream and a static mixer (170) disposed in a downstream. An additive supplied through an orifice (150a) passes through the sulzer mixer (160) disposed in the upstream. As the sulzer mixer (160) is superior in dividing the flow, the additive is uniformly dispersed in a dope pipe (152). Thereafter, the additive passes through the static mixer (170). As the static mixer (170) is superior in reversing the flow, the additive and the primary dope are further stirred and kneaded. The inline mixing device (53) uses the two different kinds of mixers for effectively mixing the additive and the dope while taking advantages of each mixer.

Description

technical field [0001] The present invention relates to a method and an apparatus for the manufacture of coatings. More specifically, the present invention relates to methods and apparatus for making coatings for polymer films for optical applications such as LCDs or similar applications. Further, the present invention relates to a method for producing a film of paint produced using a method and apparatus for producing paint. Background technique [0002] Various polymers are used to make optical polymer films. Specifically, a cellulose acylate film, which has transparency, moderate moisture permeability, large mechanical strength, and low dependence of dimensional stability on humidity and temperature, is a widely used film. [0003] LCDs are provided with a polarizing filter and an optical compensation film, and the polarizing filter generally has a structure in which a polarizing film is sandwiched between two protective films. Recently there are cases where the optica...
