Title:
LAMINATE AND RESIN FILM
Document Type and Number:
Japanese Patent JP2019151815
Kind Code:
A
Abstract:
To provide a resin film and a laminate, achieving moisture heat resistance and post processing suitability while maintaining flexibility and high stability.SOLUTION: There is provided a resin film containing a polyether segment, a (meth)acryl segment, and an urethane segment, and satisfying following conditions 1 to 5. Condition 1; 5% strain stress is 10 MPa or less. Condition 2: Elastic recovery rate at deformation volume of 20% is 70% or more. Condition 3; An absolute value of dimensional change rate at 150°C is 10% or less. Condition 4; a ratio between the largest peak intensity P1 of peaks derived from a carbodiimide group and an isocyanate group in FT-IR spectrum and peak intensity P2 caused by NH stretching vibration of an urethane group, P1/P2 is 0.01 or less. Condition 5; a ratio between stress F4 when the resin film is stretched with strain amount of 100% at 23°C a stress F5 when the resin film is stretched with strain amount of 100% at 23°C after the lapse of 500 hr. at 85°C-85%,, F5/F4 is 0.4 or more.SELECTED DRAWING: Figure 1
