Document Type and Number:
WIPO Patent Application WO/2016/159147
Kind Code:
A1
Abstract:
The present invention provides an epoxy resin composition comprising at least the following component [A], component [B] and component [C], the epoxy resin composition being characterized in that: the mixture of component [A] and component [B] is a mixture that, when temperature is increased at 2°C/min, begins to thicken at temperature (T1) and completes thickening at temperature (T2), temperature (T1) being 80-110°C and temperature (T1) and temperature (T2) satisfying the relationship of expression (1) 5°C ≤ (T2−T1) ≤ 20°C expression (1); and the mixture of component [A] and component [C] is a mixture that, when temperature is increased at 2°C/min, begins to cure at temperature (T3), temperature (T1) and temperature (T3) satisfying the relationship of expression (2) 5°C ≤ (T3−T1) ≤ 80°C expression (2). Component [A]: epoxy resin Component [B]: thickening particle Component [C]: curing agent
