RESIN COMPOSITION, RESIN VARNISH, PREPREG, METAL-CLAD LAMINATED BOARD AND PRINTED WIRING BOARD |
| 摘要 |
The present invention relates to a resin composition that becomes a cured product that exhibits force response behavior such that an area surrounded by a tensile stress-strain curve f1(x), when an amount of strain is increased from 0% to 0.3% by pulling at 999 μm/min while plotting the amount of strain on the x axis and tensile stress on the y axis, and also surrounded by the x axis, is greater than an area surrounded by a stress-strain curve f2(x), when the amount of strain is decreased from 0.3%, and also surrounded by the x axis, and the amount of change in the amount of strain when tensile stress is 0, before and after applying tensile stress, is 0.05% or less. |

1. A resin composition that becomes a cured product that exhibits force response behavior such that an area surrounded by a tensile stress-strain curve f1(x), when an amount of strain is increased from 0% to 0.3% by pulling at 999 μm/min while plotting the amount of strain on the x axis and tensile stress on the y axis, and also surrounded by the x axis, is greater than an area surrounded by a stress-strain curve f2(x), when the amount of strain is decreased from 0.3%, and also surrounded by the x axis, and the amount of change in the amount of strain when tensile stress is 0, before and after applying tensile stress, is 0.05% or less. |
