Document Type and Number:
WIPO Patent Application WO/2023/210757
Kind Code:
A1
Abstract:
Provided is a resin composition or the like that is capable of achieving both low warpage and high reflectance after a reflow step. A resin composition containing (A) a carboxyl-group-containing urethane resin and (E) a colorant that yields a white color, the resin composition being characterized in that, in dynamic viscoelasticity measurement of a cured film thereof at a frequency of 1 Hz, the temperature (Tg) of the loss tangent peak is 100°C or lower, and the peak of the loss tangent is within the range of 0.5-1.5.
