Title:
LAMINATE, AND FLEXIBLE DEVICE COMPRISING THE LAMINATE
Document Type and Number:
Japanese Patent JP2019025903
Kind Code:
A
Abstract:
To provide a laminate comprising a thinned glass plate and a resin film that are bonded together by means of an adhesive and having excellent bending resistance.SOLUTION: A laminate 1 has a configuration in which a glass plate 2 having a thickness of 150 μm or less and a resin film 4 are laminated together via an adhesive layer 3 having a glass-transition temperature of less than 5°C measured with a dynamic viscoelasticity measuring device, and has a bending resistance of 10 or more according to the following test. Bending resistance test: A set of operation comprises bending the laminate 1 by 180° from a stretched state so as to have a bending radius of 3 mm in a direction in which a surface of the glass plate becomes concave, and then stretching the laminate 1 again. The operation is performed at the rate of 43 sets per minute, and the number of the sets before a crack develops in the laminate 1 is regarded as an index of the bending resistance.SELECTED DRAWING: Figure 3
