Title:
RESIN FINE PARTICLE AND USE OF THE SAME
Document Type and Number:
Japanese Patent JP2022094770
Kind Code:
A
Abstract:
To provide resin fine particles useful as an antiblocking agent or the like which have sufficient resistance to thermal load in resin compounding, in which a residual amount of an unreacted monomer can sufficiently be reduced, and further which have a color tone imparting no influence to an optical property (colorless transparency) even when used for an optical member or the like requiring an extremely high optical property.SOLUTION: Resin fine particles comprise a copolymer including: one or more monofunctional vinyl-based monomer (A) units having a cyclic structure; one or more monofunctional alkyl (meth)acrylate-based monomer (B) units; one or more multifunctional (meth)acrylate-based monomer (C) units; and one or more multifunctional thiol (D) units in the molecular structure, in which a glass-transition temperature of a polymer formed of the monofunctional alkyl (meth)acrylate-based monomer (B) only is 50°C or less.SELECTED DRAWING: None
