Title:
ULTRAVIOLET-CURABLE COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/021891
Kind Code:
A1
Abstract:
An ultraviolet-curable composition which contains a component (A) which is a polymerizable compound and a component (B) which is a filler, wherein: the average value of the parallel light transmittance at a wavelength of 380-780nm through a cured film (thickness of 100μm) of the ultraviolet-curable composition is at least 40%; the thermal conductivity obtained from formula (100) of a cured film (thickness of 100μm) of the ultraviolet-curable composition is 0.25W/m·K or higher; and the viscosity of the ultraviolet-curable composition measured at 25°C by using an E-type viscometer is 0.1-1,000 Pa·s, inclusive. (100): thermal conductivity=density×specific heat×thermal diffusivity
