Title: Biaxially oriented laminated polyester film for laminating metal plate
Inventor: MATSUI RYOSUKE
IPC: B32B15/09
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To contrive to stabilize the formability and taste characteristics of this film by a method wherein the particle density of a layer mainly made of a polyester B arranged on at least one side of a layer mainly made of a polyester A. SOLUTION: The preferable melting points of a polyester A and/or a polyester B, which are normally obtained by polycondensation-reacting a dicarboxylic acid component such as a terephthalic acid or the like and a glycol component such as an ethylene glycol or the like are 246 deg.C or higher from the view points of taste characteristics and heat resistance. Further, the preferable difference between the melting point of the polyester A and that of the polyester B is 10 deg.C or less. In order to realize the excellent formability, especially the adhesion between the film and a metal plate after retorting, the long term stability after forming, the particle density of internal particle or the like within the surface mainly made of the polyester B must be below 500 ppm.  The particle density is more preferably below 300 ppm, since the separation of the film from the metal plate by retorting can be more suppressed. If the particle density exceeds beyond the above-mentioned range, particles play the role of the nuclei of crystallization and the crystallization at lamination or at forming is accelerated, resulting in developing the easy separation between the film and the metal plate.

Accordingly, the value (the difference between the saturation voltage and the threshold voltage) is enlarged, without injuring the speed of response rising in the neighborhood of the threshold voltage. Namely, said phenomenon is considered to be based on the increased binding force of the liquid crystal molecule against the interface of the orientation film, as the skeletons of the diamine component which is a raw material of the polyimide orientation film used for the titled element contain plural oxygen atoms respectively, thereby being strengthened the interaction of the liquid crystal molecules. Thus, the titled element having the high contrast is obtd.
