Title:
LAMINATE FILM AND LAMINATED GLASS FOR LIQUID CRYSTAL PROJECTION USING THE SAME
Document Type and Number:
Japanese Patent JP2017206012
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a laminate film giving a good appearance when processed into a laminated glass and giving a head-up display having high transparency and bright display when assembled into a head-up display.SOLUTION: The laminate film comprises A layers made of a crystalline polyester and B layers made of a thermoplastic resin B different from the crystalline polyester, which are alternately layered in total 11 layers or more; and the laminate film has a Young's modulus of 6 GPa or more in a direction of an orientation axis of the laminate film. When the film is heated at a temperature of Tg(h)-20°C for 6 hours, where Tg(h) represents a higher glass transition temperature in a glass transition temperature Tg(A) of the crystalline polyester and a glass transition temperature Tg(B) of the thermoplastic resin B, the laminate film shows a thermal shrinkage of 0.5% or more in the direction of the orientation axis of the laminate film or in a direction orthogonal to the direction of the orientation axis.SELECTED DRAWING: None
