Title:
蛍光樹脂粒子及びその用途
Document Type and Number:
Japanese Patent JP6831849
Kind Code:
B2
Abstract:
When applied to fluid visualization, the fluorescent resin particles can follow a fluid flow better and can facilitate observation of the fluid flow. The fluorescent resin particles contain a water-soluble fluorescent dye and a polymer made from a monomer mixture. The monomer mixture is a mixture of 20% to 80% by mass of a first vinyl-based monomer and 80% to 20% by mass of a second vinyl-based monomer. The first vinyl-based monomer is at least one monofunctional vinyl-based monomer selected from the group consisting of a styrene derivative having an alkyl group with 3 to 30 carbon atoms, a (meth)acrylic acid ester and a vinyl ester each having an alkyl group with 10 to 30 carbon atoms. The second vinyl-based monomer contains at least one monofunctional vinyl-based monomer selected from the group consisting of styrene, a styrene derivative having an alkyl group with two carbon atoms or less, a (meth)acrylic acid ester and a vinyl ester each having an alkyl group with nine carbon atoms or less.
