COMPOSITION FOR TEMPORARY FIXATION
Document Type and Number:
WIPO Patent Application WO/2023/181609
Kind Code:
A1
Abstract:
A composition for temporary fixation, characterized by comprising the following (A) to (C) and having a viscosity, as measured with a rotational rheometer at 23°C and a shear rate of 1 s-1, in the range of 500-10,000 mPa·s at the atmospheric pressure. (A) A monofunctional (meth)acrylate having a surface tension, as determined by the pendant drop ds/de method at 23°C, in the range of 20-30 mN/m. (B) A polyfunctional (meth)acrylate which has a viscosity, as measured with a rotational rheometer at 23°C and a shear rate of 1 s-1, of 1,000 mPa·s or higher at the atmospheric pressure, or is solid at 23°C, or has a molecular weight of 500 or higher and a viscosity, as measured with a rotational rheometer at 23°C and a shear rate of 1 s-1, of 100-1,000 mPa·s, excluding 1,000 mPa·s, at the atmospheric pressure. (C) A free-radical polymerization photoinitiator.
