Vinyl chloride-based resin emulsion, method for producing same, water-based ink, and recording paper

摘要

A vinyl chloride-based resin emulsion obtained by using a vinyl chloride-based polymer emulsion, which is obtained by subjecting a vinyl chloride monomer (B) or a monomer mixture comprising a vinyl chloride monomer (B) and an ethylenically unsaturated group-containing monomer (C) to emulsion polymerization in the presence of (A) a styrene-acrylic acid ester oligomer and/or an acrylic acid ester oligomer, as a seed (D), and subjecting a vinyl chloride monomer (E) or a monomer mixture comprising a vinyl chloride monomer (E) and an ethylenically unsaturated group-containing monomer (F) to emulsion polymerization using the seed (D). This vinyl chloride-based resin emulsion exhibits excellent water resistance, moisture resistance, high gloss and alcohol resistance if used in a water-based ink and exhibits excellent color development properties, water resistance, moisture resistance, color visibility, high gloss and release properties if used in a recording paper.

1. A vinyl chloride resin emulsion which is obtained by
emulsion polymerizing 100 parts by weight of a vinyl chloride monomer (B) or a monomer mixture of a vinyl chloride monomer (B) and an ethylenically unsaturated group-containing monomer (C) copolymerizable therewith in the presence of 40 to 500 parts by weight of (A) a styrene-acrylic acid ester oligomer and/or an acrylic acid ester oligomer, to form a vinyl chloride polymer emulsion as a seed (D), and emulsion polymerizing 100 parts by weight of a vinyl chloride monomer (E) or a monomer mixture of a vinyl chloride monomer (E) and an ethylenically unsaturated group-containing monomer (F) copolymerizable therewith, using 3 to 50 parts by weight as solids of the seed (D).
